Filtration Is A Smart Choice For Smart Irrigation Month

  
  
  
  
  
  

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.

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 proper filtration 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 clogging. Sand media filters are 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.

Two-Stage Filtration Is A Best Practice In Many Situations

  
  
  
  
  
  

Selecting the best tool and technique for a job is often a simple task. No one wants to waste time or be forced to "fix" something once it's been fixed already. As carpenters like to say "Measure twice, cut once." We always want to DO IT RIGHT THE FIRST TIME.

However, when it comes to filtering solids from water or other liquids, the wisest and most efficient method is sometimes a 2-step approach in which: 

  1. Large particles or debris are removed in the "first pass" by one method or tool (the pre-filtration step)
  2. Smaller particles are removed in a "2nd pass"

For small particle removal (Step 2), some type of barrier filter that catches tiny particles is often the tool of choice, such as bag filters and Cartridge Filtercartridge filters. But barrier filters get clogged and fill quickly when too many large particles are present -- thus the need for a pre-filter.

The pre-filter will:

(a) extend the life of the barrier filter, reducing usage and overall costs of purchasing filters and
(b) minimize labor time spent changing bags and cartridges

This is true in a wide variety of situations and applications, from turf and agriculture, to industry and more.

Example: Source Water From A River

Take, for example, a situation in which river water or sea water is used as the main source for an industrial water process. Quite often, debris of many shapes and sizes are present in the water, and no single type of filtration would remove large AND small solids very efficiently. Using a two or three-step process by taking out the larger debris and solids first with a low-maintenance solution is often used. This Step 1 can be some sort of large strainer or screen to keep large debris from entering the system, followed in Step 2 by a centrifugal separator to remove the other solids. If additional particle removal is required, some type of barrier filter could be used.

Agricultural and Irrigation Uses
There are similar applications in agricultural settings. Centrifugal separators can be used as pre-filtration to a drip irrigation system. In this situation the primary filtration concern is to keep the drip emitters from getting plugged, and sand media tank filters are most commonly used. However, a pre-filter can be used before the source water reaches the media tanks, reducing the number of backwash cycles the tanks must go through to keep operating efficiently. This backwash reduction system saves energy, water, and equipment.

Getting Tired Changing Barrier Filters?

Sometimes the original design of a filtration system consists solely of barrier filters, but maintenance staff grow tired of the constant bag and cartridge changes. When barrier filters are not changed as needed, pressure drops and other negative effects occur, and the system no longer operates within design parameters. Adding a centrifugal separator upstream of the bag filters is a perfect solution.

Sand Media Filter Efficiency Determined By Underdrain

  
  
  
  
  
  

Sand media filters may look the same, but they don't all operate the same. Some claim to use a "magical media" sand of one sort or another that has some mystical power that lends itself to finer filtration. But under a microscope, those particles appear no different than many others.

Independent testing by 3rd party agencies, however, has determined there is ONE measurable trait of a sand media filter which actually DOES make one filter more efficient than the next. That trait is "available surface area" of the underdrain. That is, the total area in square inches and mm that are available to take the flush of the filtered liquid as it passes through the sand/media/gravel pack. efficient underdrain

It makes sense when you stop and think about it. Water passes through the media tank, carrying debris which are caught in the media/sand as the water migrates towards the holes in the underdrain and out of the tank. What if there are only a FEW holes, spaced closely together? The debris "bumps" into other debris, as does the water, and the debris starts to pile up in certain places. The media sand does too. This leads to the "channeling effect" as the once level and flat bed of sand/media is turned into one that is uneven due to uneven flow through the underdrain. Watch this animation showing exactly how channeling takes place and how water flows through different styles of underdrains.

Now think of the opposite situation. Water passing through a sand filter carrying debris and leaving through a LARGE number of holes in an expansive underdrain, where the holes are further apart. The water is more evenly dispersed as it passes through the sand/media and underdrain, and no channeling takes place. The bed of sand remains relatively level and uniform because the water has more holes on the greater surface area of the underdrain to pass through the entire media filter.

Why Should You Care?

The reasons you should care about the efficiency of the sand media filter are:

  1. Greater efficiency and no "channeling" means fewer backwash cycles are required, which reduces wear and tear on ALL components of the system. This translates to longer equipment life.
  2. Water Savings.
  3. Lower pressure loss through the sand filter and reduced energy usage.
