DAX-8 resin was used for isolating hydrophilic and hydrophobicNOM compounds and GFC was for fractionating various NOM molecular weight size. UF of humic acid containing water has shown to be greatly dependent on the hydrophobic and hydrophilic components of NOM. UF perneate flux was significant affected by the hydrophilic compounds. This flux decline was primary due to the irreversible fouling resulted from the gel layer on the membrane surface. Molecular size seems to play a very important role on the UF permeate flux. Larger NOM molecules causes severe flux decline probably due to the size blocking effect. Use of PAC in conjunction with UF provide an efficient way in enhancing TOC removal from water treatment process. However, the UF-PAC hybrid system does cause even severe flux decline. we can assure that PAC is preferable to remove the non-fouling compounds from feedwater.application/pdf43847 bytesapplication/pdfzh-TW國立臺灣大學環境工程學研究所超滲透薄膜DAX-8活性碳GFC親水性疏水性滲流率積垢濃度極化NOMfoulingPAChydrophobicityultrafiltration humic acidreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/22021/1/882211E002015.pdf
