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.

“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.
