Judgement of the Supreme Court of India in the matter of Paryavaran Suraksha Samiti Vs Union of India & Others dated 22/02/2017. The Applicant seeks that the Apex Court issues direction to the Union Government, all the State Governments and the Union Territories that no industry which requires “consent to operate” from the concerned Pollution Control Board, is permitted to function, unless it has a functional effluent treatment plant, which is capable to meet the prescribed norms for removing the pollutants from the effluent, before it is discharged.

To understand the diversity and abundance of antibiotic resistance genes (ARGs) in pharmaceutical wastewater treatment bioreactors, the ARGs in sludge from two full-scale pharmaceutical wastewater treatment plants (PWWTPs) were investigated and compared with sludge samples from three sewage treatment plants (STPs) using metagenomic approach. The results showed that the ARG abundances in PWWTP sludge ranged from 54.7 to 585.0 ppm, which were higher than those in STP sludge (27.2 to 86.4 ppm).

Discharge of untreated textile effluents containing heavy metals is a serious environmental issue. Biosorption is a promising method for the removal of heavy metals. The present study analyses the biosorption of Cr(VI) from synthetic textile effluent onto tamarind bark biomass as a function of initial metal ion concentration, contact time, pH, sorbent dosage, shaking speed and temperature.
