Sand Filters

1. Vertical Sand Filters

Vertical Sand Filters
Water from open wells, canals or reservoirs can be muddy, contaminated and may contain algae/weeds and other suspended matter. These can clog the screen/disc filters instantly. Hence a sand filter is used as primary filtration before the screen/disc filter to get rid of these huge amount of suspended matter.
Sand filter uses Silica Quartz sand with Mushroom for effective filtration.
Sand filters are powder coated from the outside and painted from inside with corrosion resistant paint.
These come with flange type polypropylene heavy duty ball valves.
Back flush arrangement is also provided which enables easy flushing and cleaning.

2. Hydro Cyclone Sand Filters

Hydro Cyclone Sand Filters
A Hydro Cyclone Filter  is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance. This ratio is high for dense and coarse particles, and low for light and fine particles. Hydro cyclones also find application in the separation of liquids of different densities. A Hydro Cyclone Filter will normally have a cylindrical section at the top where liquid is being fed tangentially, and a conical base. The angle, and hence length of the conical section, plays a role in determining operating characteristics.
