 note = {ケーンジュースを種々の操作条件下で,また種々の前処理を施して逆浸透濃縮し,次の結果を得た.1.透過流束は濃度が低い程,温度が高い程,圧力が高い程,攪拌速度が速い程大きかった.2.石灰清浄は逆浸透法の前処理としてあまり効果がなかった.3.PM-10膜による限外濾過は逆浸透法の前処理として有効であった.4.ダイナセラムを用いる自己排除膜法はPM-10膜を用いる方法より優れた前処理法とみなすことができた., In the present cane sugar factory cane juice is concentrated by vaporization through application of heat in a vacuum pan. This process expends a great deal of energy. Some experiments for concentration of cane juice using reverse osmosis technique which has an advantage for energy balance have been tried. The present study was carried out to obtain additional information for application of reverse osmosis process to concentration of cane juice. Direct application of the technique to cane juice was infeasible. After several pretreatments cane juice was concentrated under different operating conditions by the reverse osmosis technique. The permeation flux was increased with lowering sugar concentration, rising operating pressure, elevating temperature and rising stirring speed. So -called "hot liming was undesirable for the pretreatment of the reverse osmosis technique. Ultrafiltration through PM-10 membrane (cut-off molecular weight of 10,000) resulted in improvement of the flux of the reverse osmosis process. Ultrafiltration through a self-rejecting membrane formed on a porous ceramic tube was more recommendable for the pretreatment because the flux through the self-rejecting membrane was larger than that through PM-10 membrane and when the permeate resulted through each ultrafiltration technique was concentrated by the reverse osmosis process, the flux of permeate through the selfrejecting membrane was practically the same as that through PM-10 membrane., 論文},
