TNPCB directives to CETP

September 19, 2014 12:00 am | Updated 05:38 am IST - Tirupur:

Tamil Nadu Pollution Control Board (TNPCB) officials have issued written directives to the Park Common Effluent Treatment Plant (CETP) in the city to immediately upgrade the pollution control measures after some lacunae were noticed in the plant’s operations during an inspection conducted following public complaints.

“We have found that steps taken to control dust/suspended particulate matter emissions and odour during the treatment of dyeing effluents was insufficient,” TNPCB District Environmental Engineer (Tirupur North) M. Malayandi told The Hindu .

People residing near the Park CETP had resorted to black flag agitation on Friday last alleging that different types of pollution caused by the CETP was unbearable.

Mr. Malayandi said the CETP had now been asked to instantly install a wet scrubber in the boiler to control the suspended particulate matter to avoid the particles from getting emitted through the boiler stack. “The plant should also set up wind barriers above the compound wall near the equilisation tank, constructed as part of the systems to ensure zero liquid discharge in the effluent treatment process.

“The barriers are necessitated to control the bad smell coming from the plant whenever the atmosphere humidity was low. The odour was mainly due to the presence of volatile organic compounds in the effluents,” he added.

In addition, the three-member dyeing units of the Park CETP had been asked to send the dyeing effluents generated to the CETP only after bringing down the temperature, he said.
