A pilot project developed with German collaboration to treat textile effluents was inaugurated at Kunnankalpalayam Common Effluent Treatment Plant (CETP) in Tiruppur on December 1.

Funding for the three-year project is from the Indo German Science and Technology Centre and is taken up under the Indo German collaboration. After lab tests, a pilot-scale electrochemical ozone oxidation process (ECOOP) reactor and CDI are installed at Kunnankalpalayam CETP and it can treat 350 litres of effluent an hour.

The technology removes colour and Chemical Oxygen Demand (COD), does not produce sludge, skips two processes deployed now in effluent treatment, and gives savings in cost, manpower and space, according to one of the principal investigators, Indumathi M Nambi of IIT Madras. The project was launched in 2020 and trials at the field level will go on for about six months. “The technology can reduce the large land requirements, high aeration, skill and time taken of a biological waste water treatment,” said a press release.

IIT Madras, RWTH Aachen University, Goeth Universitat, Tamil Nadu Water Investment Company, Ibacon and Eurofins are the partners for the project.

T. Christuraj, Ditrict Collector of Tiruppur, inaugurated the pilot plant. Details of the project are available on efectro.org
