Treatability of emerging contaminants in wastewater treatment plants during wet weather flows
… However, many synthetic pollutants, such as pharmaceuticals and personal care products (PPCPs), also enter the wastewater stream. Some of these nontraditional contaminants are not efficiently removed by the treatment process at the wastewater treatment plant. Emerging contaminants (ECs) have …
-
Enzymes : the new water/wastewater treatment chemical
Pharmaceuticals and personal care products (PPCPs) are detected routinely in raw and treated municipal wastewater. Conventional wastewater treatment processes are not effective in removing PPCP; therefore, treated wastewater discharges are one of the main entry points for PPCPs into the aquatic …
