This study is to investigate the effect of mixing time on the rejection of magnesium in polyelectrolyte enhanced ultrafiltration with PSS[poly(sodium-4-styrenesulfonate)] and PDDA [poly(diallyldimethylammonium chloride)]. The removal ratio of magnesium, the rejection ratio of polyelectrolyte, and the permeate flux were stable within 10 min of mixing. PSS is more effective than PDDA in the removal of magnesium. When PSS of 2,000 mg/L was used, the removal ratio of magnesium was 78 %. The rejection ratios of PSS and PDDA in Mg solution were up to 95.9 % and 95.7 %, respectively. |
