The dyeing plants located in tirpur have remained closed due do non implementation of zero discharge effluent treatment method. several attempts were carried and finally a treatment method/technology seems to be practical and achievable. The pollution board has given approval for a common plant located in southern part of tirupur, the arulpuram common effluent treatment plant. The Approval is for trail period of 3 month to test a new technology which seems to the solution for the zero discharge. If this trail is successful soon more common plant would start to run and tirupur will be back in full swing.
