Application/use:
Desalination of brackish water (upto 10,000 pm total dissolved
solids) to get safe drinking water.
Salient Features
of Process/Technology: The equipment employs improved
thin film composite membranes placed in a spiral configuration
inside cylindrical vessel operating at 30 kg./sq.cm pressure.
Thc 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.
Status of Commercialisation:Earlier RO technology based on cellulose acetate membranes
has been commercialised. The improved version using thin film
composite membranes is ready for commercialisation.
Minimum Economic
Unit Size: 30,000 L/day for a unit
Indicative cost/unit:
Rs. 40 lakh
Equipment and Machinery:
RO plant available from CSIR licensee.
