Contamination of soil and groundwater with pesticides is mainly caused by old ecological burdens. This study focuses on the treatment of groundwater contaminated with chlorinated pesticides. The contaminants mainly include α-HCH, β-HCH, γ-HCH, HCB, DDE, DDD and DDT. Reverse osmosis technology using RO98pHt polyamide membranes was used to remove the pollutants under batch process conditions. The observed rate of removal ranged from 98.4% to 99.7%. Total dissolved content solids decreased from 1.35 g/dm3 to below 0.05 g/dm3.
