Description
Pharmaceuticals and Personal Care Products (PPCP) represent an emerging subject of concern in thedrinking water industry. Surface waters influenced by wastewater effluent discharges receive increasedattention when they are used as drinking water resources, due to the persistence of some of thosecompounds in the environment. One key component of risk identification and management is to know thefate of those compounds during drinking water treatment. With that knowledge, treatment processescould be optimized according to PPCP removal objectives.The objective of this study is to evaluate activated carbon adsorption and membranes as candidateprocesses for PPCP removal. The results conducted on 8 different compounds from different types showthe efficiency of those polishing processes. In Europe, most surface water treatment plants have multibarriertreatment targeting at the removal of micropollutants like pesticides. They include one or severalof the following processes: granular activated carbon (GAC) filtration, ozonation + GAC filtration, ultrafiltration membranes + powdered activated carbon (PAC)adsorption (Cristal® process), nanofiltration. Therefore, a PPCP contamination of tap water producedfrom surface water is quite unlikely. Only X-ray contrast media could be the exception, with pooradsorption to GAC and poor sensitivity to ozone. Includes 12 references, tables, figures.
