摘要：

A hybrid membrane separation technique was investigated for the selective removal of metals from ground waters. This two-step process included the addition of a water-soluble polymer to bind the metals which was followed by microfiltration. This method was used for the extraction of hazardous components of ground water and for reduction of hardness. The influence of several process parameters on the efficiency of the membrane separation was studied. This paper describes results of the experiments carried out on a bench-scale level.
