Brief Description

Description :

Salient features of the technology: Multi-stage gravitational based community defluoridation plant . Cartridges are comprised of naturally available sand, gravels along with R D modified multifunctional natural adsorbents . Flow rate ~ 700L/ hour Storage capacity ~ 1000 L . Attachable to Mark-II hand pump ( non-electricity based) [Optional] . Simple in design-operation and maintenance . It can reduce F- concentration from ~ 8 ppm to below 1.5 ppm . Defluoridation plant comprising of naturally abundant adsorbents materials in the market is unavailable till now. So the developed filtration plant will be very much effective in commercialization. The developed prototype may be deployed in several govt. sectors like school, colleges, hospitals etc in the fluoride affected areas in West Bengal through different Govt. /NGOs. The technology has been transferred to 5 Indian Industries in non-excl. basis. Application:Environmental (Clean Tech.) - Water treatment.
