Effect of Different Organic Fraction on Membrane Flux Declines
|
Abstract:
Organic matter in the tap water was isolated into strongly hydrophobic acids,weakly hydrophobic acids,charged hydrophilic and neutral hydrophilic by DAX-8,XAD-4 and IRA-958 synthetic resins.Filtration tests using polyvinylidene fluoride(PVDF),polyethersulphone(PES)and cellulose acetate(CA)membranes were conducted to investigate the contribution of different organic fractions to membrane fouling.The results show that in filtration of raw water,flux declines with PES,PVDF and CA membrane are 67%,59% and 19% o...
