Pharmaceuticals and Personal Care Products (PPCP) represent an emerging subject of concern in the
drinking water industry. Surface waters influenced by wastewater effluent discharges receive increased
attention when they are used as drinking water resources, due to the persistence of some of those
compounds in the environment. One key component of risk identification and management is to know the
fate of those compounds during drinking water treatment. With that knowledge, treatment processes
could be optimized according to PPCP removal objectives.
The objective of this study is to evaluate activated carbon adsorption and membranes as candidate
processes for PPCP removal. The results conducted on 8 different compounds from different types show
the efficiency of those polishing processes. In Europe, most surface water treatment plants have multibarrier
treatment targeting at the removal of micropollutants like pesticides. They include one or several
of 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 produced
from surface water is quite unlikely. Only X-ray contrast media could be the exception, with poor
adsorption to GAC and poor sensitivity to ozone. Includes 12 references, tables, figures.
