A special monitoring team completed the collection of effluent treatment data for three months from the Common Effluent Treatment Plants on Saturday to ascertain whether the ‘zero liquid discharge’ norms were followed at the plant.
The data obtaining, carried out in two phases, was necessitated after one of the member units of the CETP moved the National Green Tribunal (NGT) alleging that the plant was not following the ZLD norms as per the directions of the Madras High Court.
The NGT had asked the same monitoring committee constituted by the Madras High Court to supervise the effluent treatment and pollution issues in Tirupur, to find out whether the Murugampalayam CETP committed violations of pollution control norms and submit a report to Tamil Nadu Pollution Control Board head office.
During the second and final phase of the data collection on Saturday, the monitoring team members comprising three TNPCB officials and a representative from legal community, collected the last three months’ effluent treatment data from the plant.
“Data pertaining to inflow of effluents from member units and the quantum of water coming after the reverse osmosis process that been sent back to the members units, were analysed.
“Besides these, the amount of sodium sulphate, extracted from the concentrated brine solution coming from the mechanical vapour re-compressor, which too was sent back to the member units for reuse, too have been computed,” TNPCB officials told The Hindu . The compilation and analysis of these data would give the clear picture of whether the plant violated the ZLD norms or not, the officials explained.
