摘要
本文简述了从不同型号的纳滤膜元件中选出一种用于卡那霉素浓缩,将卡那霉素浓缩近20倍,纳滤膜对无机盐的截留率约50%,对卡那霉素的截留率均在98%以上。为生产节约了大量的能源,同时提高了产品收率和纯度。由于有较高的截留率,减少了废水和其它污染物的排放量,保护了环境,带来显著经济和社会效益。
A nonofiltration membrane-DK4040 was used to concentrating kanamycin, which was selected from several nanofiltration membrane types on the base of pilot test. The feed may be concentrated by about 20 times. The salt rejection membrane was about 50%, and the rejection of kanamycin is more than 98%. The nanofiltration technology saves lots of energy, and also heightens the quality and production of kanamycin. Because of high rejection, it reduces the wastewater and other pollution, and thus improve the enviroment.
