Water Filters

How to choose your irrigation filter

1. Screen filter

   This is the most commonly used filter by farmers whose water is supplied by gravitational means. It filters water under low pressure with a cloth like screen made of plastic or steel gauze. Screen filters are easy to clean by wiping the screen within every so often to rid it off accumulated dirt and other particle material. They are the cheapest, and cannot work on very dirty water because they clog easily

2. Disc filter

Is for farmers whose water is under high pressure. Inside, it has a series of round discs vertically compressed together. Dirt particles under high pressure cannot pass on to block emitters. So, clean water drips to the crop. Disc filters reduce water pressure to the farm, so a grower must work out the irrigation water pressure requirement against the pressure loss to expect once the disc filter is in place

3. Sand filters

They filter water under very high pressure through a column of sand particles. Grekkon Limited will install sand filters in large irrigation projects. Here huge volumes of water are pumped under very high pressure. They are the most effective filters because sand catches all debris and the water out is always clean. They are used on very dirty water
