Abstract
In this study, an aqueous solution containing a mixture of heavy metal ion Cr(III) were treated by polymer enhanced Nanofiltration using polyethylene glycol as a binding agent polymer. The performance of PEG in removing heavy metal ion Cr (III) was compared with PEG and without PEG addition using polyamide Nano filtrationmembrane. The percentage rejection of heavy metal ions was studied under the different value of pH, metal ion concentration and flow rate. AtpH 10,percentage rejection of heavy metal ion was highest at around 99.2%,whereas,at 200ppm concentration and at 3(l/hm2)flow rate percentage rejection of heavy metal ion with PEG was highest 99.5%,it was found that PEG gave higher percentage rejection of Cr(III) ion than without the addition of PEG.
