Questions frequently asked by clients.

Can I filter irrigation water?
Regardless of how clean your water may seem to be, one must filter water for irrigation. Every irrigation system needs to have a filter. A filter ensures that there are no impurities getting into the water that may clog your drip kit emitters and cause losses.
What is the use of filter to irrigation?
Filters prolongs the life span of a sprinkler system. Especially for drip kits, they are a necessity as they prevent blockage of emitters.
Which filter is best for drip irrigation system?
In the case of drip irrigation you should always add a backup disc filter when using a centrifugal filter(sand separator) as a safety precaution. A sand separator filter (hydro-cyclone) is used in combination with a filter media after it has an excellent combination. Disc filters are commonly used to filter water from creeks, ponds, reservoirs, water catchment tanks and other sources that contain algae. Sand media filters are designed to remove organic material from large irrigation systems. The level of filtration depends on the sand used in the filter.
Should filter go before or after pump?
Filters should be placed on the pump outlet. If you put the filter on the inlet it may cause pump cavitation but on the output side the pressure will push the water through with no problem. 
NB: Filters serve a critical role in many common applications. Such applications include power supplies, audio electronics, and radio communications. Filters can be active or passive, and the four main types of filters are low-pass, high-pass, band-pass, and notch/band-reject (though there are also all-pass filters)

Irrigation filters definition-During irrigation it is easy for the water system to clog due to the impurities found in the water. water. In order to prevent this from happening, one requires to purify the water before letting it into the water system. This can be achieved by the use of a filter. A filter separates clean water from sediments that may clog the pipes and only lets clean water to pass through thus preventing blockages.

What is the procedure for cleaning irrigation filters?
When cleaning an irrigation filters in Kenya ensure that the water source is closed, and proceed to disconnect the filter from the pipes and connectors that it is attached to. Detach the top and the bottom of the filter by unscrewing it gently. Once separated, remove the disc from the body of the filter. Proceed to clean all parts of the filter using a wire brush. Once done, let them dry and put the parts back together for use.

There are three stages of filtration namely: Mechanical, chemical and biological.
However some irrigation filters that are capable of cleaning themselves after use. Here,through the outlet, once the pressure differential reaches a preset level the system activates its self-cleaning cycle by opening the flushing. Valve A self-cleaning strainer (or self-cleaning filter) is a type of water filter which utilizes system pressure to clean itself.

Irrigation filters flow rate.

Velocity is the speed of the flow, which is how fast the water runs in the pipe. Velocity is measured in feet per second (fps). It is often recommended that one does not exceed 5 fps in irrigation. This is where pipe size comes into view during planning. A simple  design flow rate for a trickle irrigation system is about 25 gallons per minute per square foot (gpm/sq. ft.). Most systems are designed to allow more than one filter at a time in order to increase the filtering capacity.

How does a disc filter work?
A disk filter is constructed from several flat, grooved disks arranged tightly on top of each other and enclosed inside a casing. Water flows into the filter casing, surrounds the stacked disks, and is forced through the grooves by water pressure, removing the impure materials.
