Drip Irrigation Filters Manufacturers & Suppliers in India
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.
Types of Kothari Filters Available-
Kothari, one of the most reliable drip irrigation manufacturers & suppliers in India, offer wide range of Primary & secondary filtration. Here Secondary filtration is compulsory in Drip Irrigation, Fogging, Micro sprinklers, and mini-sprinklers & in Pop-up Irrigation.
The secondary filtration is provided to block the particles of hole size many times lesser than the pathway width of the dripper so that the particle passing through the secondary filter, should easily pass through the dripper pathway.
- Screen Filter: Kothari is having different types of screen filters ranging from 20m3/Hr to 50m3/Hr. Those are available in manual, semi-automatic & fully automatic filters depending on their type of cleaning system. The fully automatic filters are also available in higher capacity ranging up to 280m3/Hr.
- Disc Filter: Here element is made of different discs.Are available in sizes ranging from 20m3/Hr to 60m3/Hr
The Primary Filtration is optional & is used as per the water quality. It includes Hydro cyclone & Sand Filter.
- Sand Filter: It is used for eliminating biological elements from water. The layer of three dimensional quality sand is used for the same. Kothari Sand Filters are available from 20m3/Hr to 50m3/Hrcapacity. Kothari also provide auto backwash assembly along with the same.
- Hydro cyclone Filter: It is used to separate sand particles from water. Here Centrifugal action separates sand particle from water. Those filters are also available from 20m3/Hr to 50m3/Hr capacity. For using the above filters for the higher capacities the battery system is adapted. Also the maintenance of the above filters is easier one & use & maintenance of the same increases the life of the system tremendously.
|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|
