What is Drip Irrigation?

The drip Irrigation is the artificial application of water as per the daily need of the plant directly to the plant root zone. Here drip irrigation is a low pressure operation usually having operating pressure of 1 Kg/cm2.

Need of Filter

For the drip system, dripper is the vital part usually having zigzag pathway for discharging of water. The zigzag pathway creates turbulent flow for throwing out any physical particle entered in drip system. But the particles bigger than the pathway size can choke the dripper or can hamper the performance of the drip system. Hence the Filter is used to avoid those foreign particles from entering the drip system. In view of this it is necessary to look for reliable drip irrigation filters manufacturers & suppliers in India.

Types of Impurities

There are 3 types of impurities Physical, Chemical & Biological impurities present in water. Drip Filters are designed to separate physical & biological impurities while chemical impurities get percolated in the drip system.Physical impurities include Soil Particles while biological impurities include zooplankton, Bacteria, Algae & Fungus etc.

Use of Filter as per the type of impurity in Water
Sr.no Type of Water Source Type of Impurity Type of Filter Recommended
1 River Water Contains silt, sand and various kinds of organic matter including tree trunks, leaves etc. Screen or Disc + Sand Filter
2 Bore well Water Often contains high level of sand or soil particles Screen or Disc + Hydro cyclone Filter
3 Lake & Reservoir Water Rich in organic matter such as Bacteria , green algae and one celled organisms Screen or Disc + Sand Filter
4 Well Water Usually contains a high percentage of fine sand. Sometimes contains Iron, Sulfur , Magnesium bacteria , floating minerals (like mica) etc. Usually Screen+ Disc, If high Algae then recommended Sand Filter
5 Effluent Water(after sec. tre.ment) Rich in organic matter and solid particles (algae and zooplankton) Screen or Disc + Sand Filter
