Abstract:We do UF experiment of PEG20000、PEG10000、PEG4000 solution by polysulfone hollow fiber ultrafiltration membrane ,whose molecular weight with retention is 6000. And determine the concentration of polyethylene glycol
through the method of Spectrophotometric.Discuss the effect to PEG of different molecular weight by ultrafiltration. Study the feed concertration,flow rates,ultrafiltration time to place the effect of PEG.And we determine the optimal solution peration flow of 2.0 LPM,the PEG molecular weight of 10000,liquid concerntaion of 20mg/L.
Key words EG;ultrafiltration;rejectio |
