Conventional treatment plants can be upgraded with post treatment alternatively the removal of pharmaceuticals could be achieved directly at point sources.
The pharmaceutical and personal care products PPCPs are emerging pollutants which might pose potential hazards to environment and health. These pollutants are becoming ubiquitous in the environments because they cannot be effectively removed by the conventional wastewater treatment plants due to t .Cited by: 742
Research on the removal of micropollutants i.e. pharmaceuticals has received a lot of attention in the last few decades. Wastewater treatment plants WWTPs act as the final checkpoint in controlling the quality of wastewater before discharge into receiving water.
