The Hindu Business Line : Renuga Tex unveils in-house effluent treatment model

THENI-BASED composite textile company Sri Renuga Textiles Ltd has unveiled a total effluent treatment solution aimed at zero discharge norm for the textile wet-processing industries.

Developed in-house, the `Flash-tech enviro systems', an improvised treatment process of evaporation technique module, will offer less breakdown ratio compared to similar evaporator-based treatment plants present in the market.

In addition, the technology offers higher effluent treatment efficiency by consuming less power and steam and ensures recovery of 90 per cent of effluent water for reuse and 99 per cent of the salt used in recycling process, says Mr N.R. Manivannan, Director of Sri Renuga Textiles.

He said that one of the key stumbling blocks in efficient operation of the evaporator technology treatment models was the frequent salt deposition and consequent scale formation in evaporation tubes which declined performance. Further, these techniques were predominantly mechanical treatment-centric and hence missed on the process of preventive technology. But the new technology concept evolved by Flashtech Enviro Systems, a division of the Sri Renuga Textiles, has introduced additional controls and improved heat transfer system which eliminate salt deposition. The new technique also eliminates the problem of sludge collection.

The Director of the Rs 150-crore Renuga Textiles said that his unit had put in operation its in-house technology effluent treatment plant six months before.

Flashtech Enviro Systems seeks to sell the new solution to wet-processing industries catering to Tirupur/Erode and Karur textile manufacturing zones which together account for Rs 10,000-crore business.

Apparel/made-up exports also have environmental problems from textile effluent discharges and face penal action for non-adherence to the effluent discharge norms of the State Pollution Control Board.

Renuga Textiles is eyeing small and medium-sized process houses with a daily processing capacity of up to five tonnes as potential buyers of its technology solution.

As for the pricing, a plant that is capable of handling 1,00,000 litres water for processing (with a 10,000 litre load of dye bath) would cost anywhere between Rs 35 lakh and Rs 45 lakh, depending upon the layers of evaporators and technology options, said Mr Manivannan.
