Proposal submitted for reverse osmosis plant

By Our Staff Reporter

COIMBATORE, SEPT. 27. The Perundurai Common Effluent Treatment Plant (CETP) for the textile processing units at the State Industries Promotion Corporation of Tamil Nadu (SIPCOT) Industrial Growth Centre, Perundurai, has submitted a proposal for installation of a Reverse Osmosis (RO) system.

The CETP officials said that the proposal had been submitted to the Tamil Nadu Industrial Development Corporation (TIDCO) for assistance under the Assistance to States in Infrastructure Development for Exports (ASIDE) scheme of the Centre. "It is planned to install an RO facility of 10 lakh litre capacity at the CETP." Tenders would be floated shortly.

At least 85 per cent of the treated effluent passed through it could be reused. Primary treated effluent would be sent to the RO system.

Pilot project

This would be a pilot project at a total cost of about Rs. 5 crores and the CETP members would contribute nearly Rs. 2.4 crores. Depending on its success, a large-scale RO plant could be set up, they added.

The CETP was formed by 14 textile processing units at the centre out of which 10 were operational now. The effluent generated in these units was segregated at the unit level mainly according to the level of the Totally Dissolved Solids (TDS).

While the effluent with less than 2,000 ppm of TDS was sent to the "wash water treatment plant" at the CETP, the "concentrated dye bath" was treated using the multiple effect evaporator. The installed capacity of the wash water treatment plant was 36 lakh litres a day, they added.
