DESALINATION OF BRACKISH WATER BY REVERSE OSMOSIS

DESALINATION OF BRACKISH WATER BY REVERSE OSMOSIS
Detail:
Product: Reverse osmosis equipment.
Application: Desalination of brackish water (upto 10,000 ppm total dissolved solids) to get safe drinking water.
Feature: The equipment employs improved thin film composite membranes placed in a spiral configuration inside cylindrical vessel operating at 30 kg/cm2 pressure. The hardness and fluoride contents are reduced by 85% and bacterial load by 99%. The technology is modular; providing scope to enhance capacity by adding membrane elements. There is no problem of scale or corrosion. It requires electrical power, which also can be generated through solar panels.
Commercialisation: Earlier RO technology based on cellulose acetate membranes has been Commercialised. The improved version using thin film composite membranes is Ready for commercialisation.
Economy 30,000 L/day for a unit.
Investment: Rs. 40 lakh.
Equipment: RO plant available from CSIR licensee.
Raw materials: --------
Institute: Central Salt & Marine Chemicals Research Institute.
