Sustainable Water Recovery from Cold Roll Mill of Integrated Steel Plant of JSW Steel Limited

Water management plays a vital role in steel industry. The present work is carried out in cold rolling mill aiming to recovery maximum water. In CRM process the acid waste, alkaline waste and oil and grease wastewater generated. This wastewater is treated in effluent treatment plant and then it is desalinized to avoid the salt concentration in water circulation system by implementing ultra-filtration and RO system. It is found there is membrane fouling in RO3 system due to increase in hardness at the inlet it is reduced by adding lime and soda ash. Results shows that most salts are removed by UF and RO treatment and high quality of water is obtained. It is found that reusing the desalinated wastewater found more economical then discharging.
