Abstract
In this research, composite polyvinyl chloride ultrafiltration (PVC-UF) membrane was used for peat water treatment. The UF membrane was prepared by mixing polyvinyl chloride (PVC), polyethylene glycol (PEG400), ZnO, acetone, and DMAC. The concentration of PVC was varied from 10 to 14 wt.%, while the PEG400 was varied from 0 to 10 wt.%. The concentration of acetone and ZnO was fixed at four (4) wt.% and two (2) wt.%, respectively. Immersion precipitation method was used to form the membrane structure. The experimental results showed that higher humic substance rejection (>50%) was achieved when 12 wt.% PVC and 10% wt.% PEG was added into the polymer solution. The permeate flux of the membrane was above 100 L/m-2h-1
