VARSHA a Rapid Sand filter Developed by Green Technologies to filter rainwater from the rooftop, |
|
| |
|
|
| |
VARSHA is made from a High Density Poly Ethylene (HDPE) drum. Rainwater enters through the inlet into a perforated PVC pipe which is the first sieve that keeps out large leaves, twigs etc. Rainwater coming out of the pipe passes through series of filter media, and finally to the outlet which can be conncected to the stroage system for non potable usage or for recharging open well/borewell. |

How does Varsha work |
|
| |
|
|
| |
Rapid sand filtration is the flow of water through a bed of granular media, The purpose of this filtration is to remove any particulate matter. |
|
| |
|
|
| |
Sand filtration is a "physical-chemical process" for separating suspended and colloidal impurities from water by passage through a bed of granular material. |
|
| |
|
|
| |
| Water fills the pores of the filter medium, and the impurities are adsorbed on the surface of the grains or trapped in the openings. The key to this process is the relative grain size of the filter medium. |
