抄録: A new type inorganic membrane-porous glass is applied for both cross-flow filtration modes. The laboratory results show that permeation of Albumin passing through 30 nm porous glass filter can be negligible (<0.015%). The filtration behavior of natural DOC consistently shows a decreasing concentration in the permeate with increasing CFs. Thus, the permeation of HMW molecules is minimal during CFF using porous glass filter, even under high CFS (CF>50). During filtration of Bora Bay seawater, OC concentration of permeate (C_p) first is at very beginning (i.e. in the first liter of permeate) higher than the OC concentration of pre-filter sample, and then lower and lower with permeate volume and concentration factor increasing. The speed of OC concentration decreasing is very rapid at beginning. After the CF>4 using regular concentration mode and after CF>12 using diafiltration mode, the variation of Cp becomes slightly as CF continuously increased. Thus, the organic matter of Bora Bay seawater can easily pass through 30 nm porous glass filter, in another word, a large amount of organic matters of Bora Bay seawater can not be retained by 30 nm porous glass filter. The results show that major organic matters of Bora Bay seawater are smaller than 30 KDa.
