Description

Membrane filtration of ground water, which included high concentration of Fe, Mn and dissolved-SiO2, was investigated using 5 kinds of membrane. In the case of air oxidation, particle size of oxide was 0.03-0.1μm, and its coagulation state was poor. So, perfect removal of Fe by MF membrane was difficult without Alum dose.<BR>In the case of chlorine oxidation, particle size of oxide was 0.01-0.03μm, and the removal of Fe by membrane (pore size below 0.1μm) is perfect because of high coagulation state of oxide. The removal of Mn by MF and UF membrane after chlorine oxidation was 80-90% but concentration of Mn was not below 0.01mg/l. The concentration of Mn by the combination of Mn-sand filtration after membrane filtration reaches below 0.01mg/l. The increase of filtration resistance of UF and MF membrane depends on the pore size and the coagulation state of oxide by the difference of oxidation method.
