Abstract

This paper presents a study of the application of nanofiltration for pesticide removal. Four different membranes were compared for their rejection of six important pesticides (simazine, atrazine, bentazone, diuron, DNOC and dinoseb). The results showed that the membrane material has a large influence on the rejection. It was found that the Hydranautics PVD1 membrane had the best performance with rejections between 85% and 100% for the six tested pesticides. The worst performance, considering the pesticide rejection, was found for the Fluid Systems 4 x 21 PZ membrane. The rejections of this membrane ranged from 25% for diuron and DNOC to 95% for bentazone. In addition to the pesticide removal, the rejection of natural organic matter, calcium and chloride was monitored. The four membranes showed similar rejections of UV-absorbing compounds (> 97%) and DOC (± 90%). For the rejection of calcium and chloride the membranes showed typically the performance of nanofiltration membranes: high calcium rejection and low chloride rejection.
