Enzymatic treatment of pharmaceuticals and personal care products (PPCPs) in municipal wastewater
Conventional wastewater treatment plants do not effectively remove pharmaceuticals and personal care products (PPCPs). As a result, PPCPs enter the environment via treated wastewater discharge. Enzymatic treatment, using the laccasemediator system, is a novel biochemical process that has been shown …
