Make Your Own Filtration Test Kit - Any Jar Will Do!

Posted by Lakos Marketing on Wednesday, January 27, 2016

When you've got sand in your water, all it takes is a clear jar to decide if a LAKOS Sand Separator can solve that problem.

Use any clear jar. And all it takes is about 3-4 minutes. Here's how:

  1. Get a sample of the sand coming through the water system. From the hot water heater. From the toilet tank. From a plugged cartridge or screen filter. Whatever you can get your hands on from within your water system.

  2. Add the sand to a jar of clean water and shake the jar to mix the sand & water.

  3. Let the mixture stand and watch what happens:

    • • Particles that settle to the bottom within 2-3 minutes   can be removed with a LAKOS Pump Protection         Sand Separator.

    • • Particles that settle to the bottom within 3-4 minutes   can be removed with a LAKOS Sand Separator           installed after the pump.

To Filter or Not to Filter

Posted by Lakos Marketing on Sunday, December 20, 2015

Very often, the first thing people think about when they have something in their water is, “I need a filter.” The next thing people think about is the downside of using a filter. Filters get dirty, create pressure loss, and often need to be taken apart and cleaned. As quickly as someone thinks they need a filter, they just as quickly talk themselves out of it.

It is important to understand that the LAKOS Sand Separator is and is not a filter. The LAKOS separator is a particle separator and, by definition, not a filter. There is a need for all types of products in filtration, from particle removal to water treatment. The LAKOS separator is most typically a prefilter, installed after a pump and before finer filters or water treatment. The LAKOS system removes larger particles so that finer filtration systems can take over after the removal of those heavier sediments or solids—the ones that would settle out in three to four minutes in still water or fluid. With larger particles removed, finer filters and water treatment can do their job better with less maintenance and servicing and fewer replacements.

A separator’s role as a first-stage filter is critical. For example, a number of traditional filtration devices are meant to change the taste, color, and odor of water or fluid by using extremely fine membranes, screens,and treatment media; the problem is that they are very vulnerable to the bulk of the sand, sediment, grit, and precipitated minerals—all the different types of harmful particles that can clog and abrade the various components of the system. Fine filtration systems are typically not designed to filter larger particles.

The problem can be resolved by recognizing that it is more efficient to use two or more filters when faced with two or more types of contaminants in the water. After the LAKOS separator does its job, the finer traditional filters can efficiently remove the finer particles. Users often do not realize that common 2- to 5-micron filters will need to be cleaned or replaced far more often if relied on to remove heavier, larger particles. Debris will accumulate quickly and shut a fine filter system down. The LAKOS system addresses all these concerns. It does not create the same loss in pressure and does not need to be cleaned as a standard filter. The product purges just the dirt and very little water and, therefore, wastes little water. Many other types of filters use a large amount of water to backwash or flush the debris from filter screens. Using the LAKOS separator as a prefilter allows the finer filtration systems to run longer and more efficiently. LAKOS helps to eliminate the larger particle problem instead of just moving it around.

Separators

LAKOS Sand Separators remove sand and other solids from pumped water and other fluids. There are no screens, cartridges, or filter elements. The key to removing solids is centrifugal action.

As water enters the sand separator, it immediately transfers from the outer chamber to the inner chamber through tangential slots. Those slots maintain the centrifugal action in the same direction and accelerate the water into a smaller diameter chamber. That allows centrifugal action to do what gravity would do over time. So, the performance of a separator is predicated on the weight of a particle, and not on its size.

A rule of thumb is that if the particle matter or sediment would settle within three to four minutes in still water, then those particles are separable in a LAKOS separator. Once those particles get pushed to the outside, they will gradually fall down the perimeter, past the deflector plate, and into the collection chamber. While the centrifugal action creates an outward pressure, there is also a low pressure at the center. Water follows the lowest pressure, the vortex of that tornado, and migrates upward to the center of the separator to a smaller diameter pipe—the vortex outlet. So all the water goes in, dirt is spun to the bottom, clean water spirals up the operative separator, and the particles fall to the collection chamber, where they are either periodically or continually purged from the separator to evacuate the unit.

History of the Separator

Claude Laval Jr. invented the original technology, a device called a borehole camera, which would go down into water wells and inspect for damage in order for wells to be repaired and rehabilitated. Laval’s borehole camera showed the industry that there was a lot of sand infiltration in water wells and that a product design that removed sand to protect the pumps from premature wear would be innovative. The first device to use such technology was the downhole sand separator, which protected turbine pumps in the big agricultural regions of central California. Irrigators were skeptical at first. Laval responded by inventing an above-ground version of the downhole separator to prove the theory. Suddenly, applications emerged across a wide range of activities and markets all over the world.

LAKOS Systems Have Many Applications

Since the sand separator’s introduction in central California, LAKOS has moved the separator beyond agriculture and irrigation into processing applications. Today, separators are used in municipal water systems, power plants, steel mills, oil and gas operations, HVAC, cooling tower filtration, and mining.

LAKOS systems bring filtration improvements to many activities for many entities, including individuals who use residential water well systems; landscaping businesses that need to protect sprinklers from the abrasion of sand and grit; municipal water providers that recycle water; and factories that aim to keep water losses to a minimum.

The drought in the West has increased demand for the sand separator. As irrigators adopt more efficient irrigation systems, the nozzles and orifices used to broadcast the water are becoming finer and requiring filtration sufficient to keep the flow from clogging.

Cities often come to LAKOS seeking to change their filtration systems because the current ones are so maintenance intensive. They are astonished at the improvement our systems can make. Cities can be very cautious and very conservative, but our approach to reliability can give them confidence. For example, the City of Phoenix, Arizona, equipped most of its water wells with sand separators, extending the life of water meters and reducing operating costs associated with meter repair and replacement.

Life Cycle Costs Are Competitive With Other Technologies

In comparison to LAKOS, traditional filters will be less expensive on the front end. It is important to keep in mind, however, that the cost of a separator is not just in the purchase of the unit, but in the manpower and replacements that accompany the system. The long-term costs of a LAKOS system are comparable to a traditional filtration system.

The price of the product drops with every consideration of a traditional filter. You do not have to pay to have someone clean the system or to replace the parts, and there is no worry about water loss. Most filters have ongoing replacement cycles that shut down overall services and use a large volume of water to flush the filter components, leading to water loss, increased wastewater fees, and increased energy costs.

In terms of service life, separators have roughly the same life cycle as the pipes used in a water transmission system. The sand separator does not succumb to abrasive wear as it does to corrosive wear. It is the nature of the fluid that dictates the life of the product, not the particles. There are LAKOS units that were installed 50 years ago that are still in service today. In one case, a steel mill took a 25-year-old separator system offline because it thought the service life had ended. When the system was opened up, we discovered it was in great working order and looked like a new unit.

A LAKOS separator, acting as a prefilter, can significantly change and enhance the entire filtration process for municipal water suppliers and irrigators. Our company’s approach is not just about removing particles from the water, but also removing them from the product and from the facility. I have been representing LAKOS products for 38 years. Every year, I meet people who have never heard of the sand separator. It is exciting to introduce this product to people for the first time because they are often surprised that filtration technology has become so advanced. The LAKOS system will allow many entities to adapt to a wide range of water-related challenges in the 21st century. Our goal is to continue advancing the technology to help them more effectively and efficiently meet those challenges every step of the way.

Premature Pump Failure From Sand: Symptoms & Solutions

Posted by Lakos Marketing on Monday, November 16, 2015

"I can't afford to keep replacing my pump. There's just got to be another way."
"I thought I was pumping gold ... but it was really my brass pump impellers."
"Pump wear is really costing me a lot of money in higher energy bills"


If a little sand is getting into a water system, most folks will start looking at filters. But when a pump starts to suffer from pumped sand, it gets expensive in a hurry. The pump, the plumbing & the equipment downstream all suffer.

No one likes replacing a pump. "It should have lasted longer", they all say. They start questioning the pump brand and the dealer who sold it. "Should I try another contractor?", they think to themselves.

Even the electricity bill starts looking a lot worse, because a worn pump works harder and longer to deliver the water demand.

But sand happens even in wells that started clean. Because of old well casings. Because of changing water tables. Because of all the new wells and pumps drawing from the same water table. Because the technology allows a bigger pump to fit into a smaller well and deliver more water at higher velocity ... and that velocity can bring even more sand.

How do you know if a Pump Protection Separator can help?

Diagnose the problem: Put a sample of the troublesome sand into a jar of water and shake it up. Whatever settles in 2-3 minutes or less is what's causing that pump to fail.

Get the facts: Know the pump's actual flow rate, the minimum well ID and the submergence of the pump (depth of the pump below water during operation). These facts will help us size the correct solution.

There is a solution: LAKOS is the only source for pump protection sand separators. Over 50 years of experience. Models for all submersible and turbine pumps. Call us.

Cooling Tower Basin Sweeping Offers Better Legionnaires Prevention Than Periodic Cleaning

Posted by Lakos Marketing on Wednesday, September 02, 2015


The recent outbreak o
f Legionnaire's Disease in New York City has proven once again that an ounce of prevention is worth a pound of cure. Legionella bacteria growing in cooling towers was the apparent cause of this outbreak. Once the disease was diagnosed, disinfection and testing immediately became the priority. For prevention, a cooling tower basin sweeping system, along with an effective water treatment program is an effective combination in reducing the risk of Legionella growth.

Rather than manually cleaning the tower basin at regular intervals, or (worse) when problems arise, basin sweeping filtration provides continuous removal of the particulates that provide a habitat to allow Legionella and other bacteria to grow. Cleaner cooling system water also makes water treatment more efficient, requiring less chemical use than a system without filtration. The American Society of Heating and Refrigerating Engineers (ASHRAE) has included cooling tower basin sweeping and centrifugal separators as possible aids in the prevention of Legionella.


ASHRAE Prevention Standards
Guideline 12 in the ASHRAE Handbook points out that..."Keeping the system clean reduces nutrients available for Legionella growth...(and) centrifugal gravity-type separators and bag-type filters can be used to assist in removal of debris.." Fighting Legionella is just one of the advantages of using a centrifugal separator to clean a cooling tower water system.

The newly published ASHRAE Standard 188 (Risk Management for Legionella) requires building owners to document a plan for regular inspections and maintenance of cooling towers. Section 7.2.3 b clearly states that this plan "shall include requirements and schedule for basin or remote sump cleaning." The three largest cooling manufacturers (BAC, Marley, and Evapco) all offer pre-installed basin sweeping piping configurations for their towers for ease of implementation.

The ASHRAE White Paper titled "Benefits of Cooling Water Filtration explains even more benefits of Cooling Water filtration.

Prevention Case Study
Saint John's Hospital in Indiana has heard all the horror stories. Concerned with both the risk of Legionnaires' Disease and employee injury common to manually-cleaning cooling towers, the staff at Saint John's installed continuous filtration cleaning on their cooling tower basins. The LAKOS system also made their water treatment more effective, requiring much less chemical use than before the filtration was installed.  Says their mechanical team leader, "LAKOS basin sweeping is working extremely well. I can't imagine not having it." Download the entire Case Study.

Obama Speaks Out on California Drought and Irrigation Water Savings

Posted by Lakos Marketing on Friday, February 14, 2014

The ongoing California drought has brought national attention to the Central Valley, where much of the country’s produce is grown. The situation has become so severe that even President Obama is visiting the region this Friday to bring attention to the crisis that has dried up the Valley. Analysts and journalists speculate that he will be in Fresno, CA to support legislation that will bring millions of dollars in aid to local farmers. If signed, this bill would provide hundreds of millions of dollars to farms for conservation efforts and upgrades to existing water systems.California Drought Dry Riverbed 2013 resized 600

3 Ways To Conserve During A Drought
The dry conditions mean everyone is looking for innovative ways to protect resources and equipment. Here are three ways you can do your part to help:

1. Farming communities are relying more and more on groundwater reserves, which are only getting lower. Many are drilling new wells or uncapping old ones that have sat idle for years. For these wells, sand damage can be a major problem to the pumping equipment. Installing a pump protect separator can protect pump impellers and allow the system to use less energy when extracting the water.

2. Proper irrigation filtration is key to successful water savings. Sand or other solids can plug up nozzles, sprinklers, or drip emitters leading to wasted water and energy. But without a good underdrain design, sand media filters can require extra backwashing, wasting even more precious water. Make sure you’re using effective media tanks in your irrigation system, and even consider a pre-filtration system for reduced backwashing.

3. Encourage your local schools and governments to institute water saving practices and educational programs. Municipal water systems can install separators like the PWC to save energy and water. Schools can educate the youngest members of our community so that the next generation of citizens continue to innovate new technology for saving our planet.

Filtration Is A Smart Choice For Smart Irrigation Month

Posted by Lakos Marketing on Monday, July 29, 2013

Every July is Smart Irrigation Month sponsored by the Irrigation Association, and this year, it’s more important than ever. With record-breaking heat across the United States and other regions, everyone is looking towards creative technology and solutions to conserve water. With the U.S. population projected to grow an amazing 42% between the years 2010 and 2050, water is becoming an increasingly rare resource. Fortunately, there’s a few ways everyone from the homeowner to the farmer that can do their part to conserve water with the latest filtration technology.


Residential Filtration Can Save Water, Energy, and AppliancesSmart Irrigation Month

Smart Irrigation Month doesn’t apply just to farmers. In single family homes, outdoor uses like landscaping and irrigation account for nearly one third of homes’ water use, (followed by toilets and washing machines).


If you’re on a private well, an excellent way to conserve water is by installing a filtration system to effectively remove solids from your supply. Even landscape and irrigation water should be free of solids. Dirt and debris can block a sprinkler valve, permanently forcing it into the open position, potentially flooding a yard and wasting water. And in many regions, water waste can lead to heavy fines or penalties. A SandMaster separator installed before the pressure tank, or a TwistIIClean installed after it, is a great way to prevent this unnecessary flooding in your yard or garden.


Proper filtration in the home will also keep your faucets and appliances working efficiently and prevent them from clogging. According to the EPA, “water-efficient household appliances and fixtures can yield significant water savings, and careful selection of construction materials can conserve natural resources and improve indoor air quality.”


On top of all these benefits, smart water use can save energy: “Water treatment and distribution are highly energy-intensive, as are many water uses that involve heating, chilling, softening, or pressurizing it for various needs.” So by utilizing filtration, other equipment (like pumps) don’t have to work as hard, preserving energy along with water savings.


Reduced Backwashing Is Smart Irrigation

The water saving concepts in residential filtration also apply to irrigating farmland; care should be taken to prevent clogging and wasted resources. Sprinklers and drip emitters can clog, causing excess watering and energy waste. Media tanks like the ProII or SST are ideal for removing unwanted solids in these applications.


But to save even more water, media tanks can be paired with an IHB centrifugal separator to create a Backwash Reduction System (BRS). By stopping excessive backwashing, water loss can be prevented even further - now that’s Smart Irrigation! This separator can be connected to all existing sand media filters, regardless of size, manufacturer, or date of installation.


Smart Technology for Smart Irrigation

Computers, technology, and filtration are constantly improving and evolving. Not only that, but they can help each other evolve. One company has been leading the charge for continuous filtration technology improvement for over 40 years. LAKOS Separators and Filtration Solutions has been improving their patented centrifugal filtration technology for decades, along with paving the way towards better community filtration education.

Retrofit Cooling Systems Operate Efficiently Thanks To Filtration

Posted by Lakos Marketing on Thursday, July 11, 2013

Energy-saving technology is constantly evolving and improving to be more efficient than ever before. Every year researchers, engineers, and scientists conduct research studies and products to improve energy efficiency in our hotels, schools, hospitals, office buildings, and more.

Cooling tower filtration in large buildings like those in New York City is essential to energy and water savingsA recent 2013 energy report this year found that some new energy efficient buildings were actually less energy efficient than older buildings that were retrofitted with the latest energy saving equipment.

According to these reports, newer buildings in Manhattan, like 7 WorldFacilities like the world famous Empire State Building retrofit their equipment to energy saving technologyTrade Center, received a lower energy efficiency score than much older buildings like the Empire State Building, which has been retrofitted in recent years. The historic Empire State building has already cut energy use by 20%, and will save the owners an estimated $4.4 million a year!

Updating older buildings with energy efficient equipment is a proven way to conserve energy resources. In fact, an NBI study found that retrofitting older buildings with energy saving equipment "resulted in energy use 50% less than the national average." These results show that new, energy efficient equipment installed in new or old buildings plays a vital role in improving energy efficiency around the world.

HVAC Efficiency Is A Global Concern

Retrofit energy solutions aren’t exclusive to the United States. Countries around the world are taking advantage of upgrading older facilities to meet modern day energy standards. In China, the government is implementing a five year plan to retrofit a remarkable 4 million square meters of building space. That’s equivalent to 16 Empire State Buildings!

Tucked away in the lush foliage of the Costa Rican Peninsula Papagayo coastline, a luxury resort had a unique problem. In addition to maintaining energy and water savings, they had to deal with beach sand and debris entering their cooling system. This debris was entering their cooling tower, preventing it from operating at optimum efficiency. The ideal tropical location wasn’t so ideal for hotel’s the cooling tower. They found their solution in a LAKOS TowerClean Separator. The patented HydroBooster water nozzles easily swept the basin debris into the separator where it was efficiently removed from the system with zero water loss or maintenance, all while using minimal amounts of energy.

New eSolutions Products Designed for Energy Efficiency

One big way these large buildings can improve their energy efficiency is through water filtration. A filter or separator can clean and protect cooling tower basinsheat exchangersspray nozzles, and chiller tubes from unwanted solids build up and fouling. Centrifugal separators have been proven to reduce maintenance costs,energy use, and water loss, all while effectively keeping cooling systems clean and protected.

One company is leading the charge in energy efficient filtration for these large buildings. Just this year, LAKOS Separators and Filtration Solutions launched their third generation of unique filtration solutions: a line of eSolutionseparators and filters that offer finer filtration using less energy. This new product line has been specially engineered with strict energy compliance guidelines in mind.

On a single pass with the new eHTX Separator, 98% of particulates down to 44 microns can be removed from a cooling system, all while using minimal amounts of energy, water, or maintenance. These separators use patented centrifugal technology to easily remove unwanted solids that can hinder system efficiency.

River Filtration Takes Center Stage During National Park Week

Posted by Lakos Marketing on Thursday, April 25, 2013

This past Monday was Earth Day, and this entire week is National Park Week -- a good time to think seriously about the natural world around us.

Water pollution causes problems in many areas of our lives, effecting our drinking supply, manufacturing processes, and irrigation methods. On almost every continent, polluted rivers, canals, aqueducts, and lakes are a growing concern. In addition to increased risks for disease, decaying vegetation, and harming regional animals, polluted source water also means clogged waterways that negatively impact our agricultural and industrial water systems.

River Water PollutionAn International Movement

The water pollution problem isn't just isolated to one country or continent; it's a global epidemic, effecting every corner of the Earth. Thankfully, several nations are leading the charge to find innovative ways to clean up the mess.

China has recently promised to spend $16 billion over the next three years to clean up the heavily polluted rivers. The Shanghai River provides water to 23 million residents, but has recently suffered from severe pollution, including thousands of dead animals infiltrating the waterways. In India, residents of Nagpur have joined forces to put an end to the Nag River pollution problem. Sewage and garbage has taken over the river making the water unusable, but a clean-up campaign has gained momentum, calling for the river’s clean up. And according to a new government report, the United States isn’t a stranger to river pollution, either. The study shows that more than half of the U.S.’s rivers can only be classified as “poor” due to pollution. Government agencies and environmentalists have used this week's Earth Day to vow action to save our waterways.

National Park Week Highlights River Pollution Problems

With this week being National Park Week in the United States, nature advocates are taking the opportunity to highlight our serious river pollution problem. They point out that a recent government study on U.S. rivers warns that our future water demands will mostly come from municipal and industrial needs, as the population continues to grow. That means the need for proper source water filtration will continue grow as well.

The Source Water Pollution Solution

Fortunately, there is an easy solution for cleaning water taken from these dirty rivers. A self-cleaning pump intake screen is a low maintenance solution that stops larger debris like fish, organics, and garbage from entering the water system. The entire screen rotates so that debris is pushed away, instead of clogging the screen, wasting time and energy. With large debris stopped before entering the water treatment system, there’s less wear and tear on pumps and finer filtration systems. With a pump intake screen, water is much easier to treat for irrigationindustrial processes, consumption, or other uses.

Download a FREE Pump Intake Screen Informational Brochure

A new and exclusive source water filtration brochure is available for the first time HERE. The informational sheet highlights all the benefits of pump intake screens, including full color drawings and pictures. Find out how these self-cleaning screens are the right choice to protect your water systems.

New Irrigation White Paper Explains the Importance of Filtration

Filtration Puts the Freeze on Winter Crop Damage
Freezing temperatures have an 
impact on agricultural regions, causing damage to fruits and vegetable crops and forcing farmers to devise ways to protect their crops from frost damage. During these harsh winter months, many farmers turn to filtration to help protect their harvest. Using micro sprinkler systems, along with a properfiltration system, water can be sprinkled on to the produce, which then freezes, releasing heated energy onto the crops. The warmth from the liquid-to-solid-state transformation keeps the produce warm enough to avoid frost damage.

Irrigation Filtration LAKOSIn order for these micro sprinkler systems to work most effectively, filtration must be used to prevent the spray nozzles from cloggingSand media filtersare the perfect filtration solution for this situation, and for extra protection, a centrifugal sand separator can be installed before the sand media tanks in the water line to remove the larger dirt and solids before it reaches the tanks and other system parts.

Irrigation Filtration Showcased at World Ag Expo Last Week

The World Ag Exposition took place last week in the heart of the agriculturally rich Central California. The Expo --the world’s largest agriculture trade show -- prominently features irrigation and groundwater filtration solutions from around the globe.

At the heart of this ag filtration show every year is the premiere brand in irrigation filtration: LAKOS Separators and Filtration Solutions. LAKOS sand media filters have been protecting irrigation systems, sprinklers, and drip emitters  for decades. Their unique underdrain system provides an optimum, even flow, while providing longer operating cycles and the best backwash results in the industry.

New White Paper Explains The Importance of Irrigation Filtration
A new, recently published white paper explains in detail the importance of irrigation filtration and how to choose the right filter for each irrigation application. Written by an industry expert, this paper was presented at the annual Irrigation Association trade show and clearly illustrates the features and benefits of each option for irrigation and groundwater applications.
