Erode:
Twenty one textile dyeing and processing units in the city were sealed today by Pollution Control Board and revenue officials for alleged violation of pollution norms and their power supply disconnected.
One of the major violations was non installation of Reverse Osmosis plants (zero discharge unit), officials said.
The Board had a few months back issued show cause notices to 95 textile dyeing units in and around Erode for non compliance of norms.
Already 74 such textile processing and dyeing units have been sealed and power supply has been disconnected.
