초록
두부순물에 함유된 가용성 고형물의 제거를 위해 두부순물을 각 역삼투막의 최대 허용압력(CA 930 : 20bar, HR95, HR98 : 60bar)하에서 역삼투처리시 HR형막의 액투과속도는 CA형막에 비해 거의 유사한 수준 이상을 유지하였으며 HR98막의 경우 역삼투 처리온도가
The effects of membrane type, temperature and pH on the permeate flux and removal of soluble solids from soybean curd whey by reverse osmosis were studied at recommended pressures for optimum performance of the membranes. The fluxes obtained with HR 95 and HR 98 membranes at 60 bar were not lower than that with CA 930 membrane at 20 bar. Soluble solid content in the permeate increased to 1.5 Brix after 90 min by CA 930 membrane, as opposed to 0 Brix with the HR 95 and HR 98 membranes. Permeate flux was increased by 28.4% as operation temperature increased from
