KARUR: The Cauvery Delta Farmers Welfare Association has urged the textile industry to experiment with use of potassium chloride and potassium sulphate instead of sodium chloride for textile dyeing process to reduce damage to water sources, agricultural land and crops.
Dyers of textile related industries mostly use sodium chloride (common salt) for colouring and bleaching purposes. In the Tirupur and Karur belt that has more than a thousand dyeing and bleaching units around 800 tonnes of sodium chloride is being dumped and washed off in an estimated seven crore lakh litres of water that mostly finds its way to the water sources and bodies, including the Noyyal, Amaravathy and Cauvery rivers.
Even if they all were to be treated and then let out, the effluent mixed water spoils the ecology irreversibly altering the nature of the land, its users and water and its consumers, including human beings and livestock. Agriculture suffered at the hands of polluters and farmers were put to great hardship.
