Treatment of Raw Water with Ultrafiltration Membrane/PAC
Raw water of Yellow River was treated by ultrafiltration process (UF) combined with powdered activated carbon (PAC) in this study. Experimental results showed that UF is a perfect physical sieving barrier to remove turbidity and algae from water, which is far superior to conventional filter bed. UF is inefficient to dissolved organic matter removal because of its large molecular weight cut-off. Combination of PAC with ultrafiltration membrane can effectively increase the removal rate of CODMn, TOC and UV254.
