Hydro-cyclone [Centrifugal Filters]: Also known as "sand separators, centrifugal filters are mainly for the removal of particles such as sand, and other solids from the irrigation water. They are ideal for situations where a pile of sand, is present in water.How it works? Dirty water enters the filter where swirl around the inside of a cylinder. The centrifugal force causes the sand particles to move towards the outer edge of the bottle, which slide slowly down the side of a reservoir below. Hydro-cyclone centrifugal filters are reasonably cheap, very simple and very effective to remove the sand from the water. Since many wells pump water with sand, It is not uncommon for a small amount of sand to pass through a centrifugal filter. 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. The hydro-cyclone removes the sand filter media and removes the material organic. It should be noted that selection of hydro-cyclone sand separator filter must be closely combined the Flow rate [m3/h or gph] of the system or the filter will not work properly. Always check with the vendor working flow-rate/pressure head loss curve guidelines on the design of a hydro-cyclone filtration system for your irrigation system, remember, a minimum pressure head-loss is necessary to achieve effective sand separation.Next Blog will be about "How to choose a filter?"
