9. As per analysis report from Board’s lab for sample collected from outlet of STP of capacity 100 KLD on 19.02.2024, in which, pH is reported as 7.3 against prescribed standard of 5.5-9.0, TSS as 32 mg/ltr against prescribed standard of 200 mg/ltr, TDS as 606 mg/ltr against prescribed standard of 2100 mg/ltr, COD as 112 mg/ltr against prescribed standard of 250 mg/ltr, BOD as 23 mg/ltr against prescribed standard of 100 mg/ltr, O&G is BDL against prescribed standard of 10 mg/ltr. All the parameters are within the prescribed standards laid down by the Board.
10. As per analysis report from Board’s lab for sample collected from outlet of STP of capacity 50 KLD on 19.02.2024, in which, pH is reported as 7.4 against prescribed standard of 5.5-9.0, TSS as 50 mg/ltr against prescribed standard of 200 mg/ltr, TDS as 1119 mg/ltr against prescribed standard of 2100 mg/ltr, COD as 148 mg/ltr against prescribed standard of 250 mg/ltr, BOD as 32 mg/ltr against prescribed standard of 100 mg/ltr, O&G is BDL against prescribed standard of 10 mg/ltr.
