超滤是一种以筛分为分离原理，以压力为推动力的膜分离过程，过滤精度在0.005-0.01 um范围内，可有效去除水中的微粒、胶体、细菌、热源及高分子有机物质。可广泛用于物质的分离、浓缩、提纯。超滤 过程无相转换，常温下操作，对热敏性物质的分离尤为适宜，并具有良好的耐温、耐酸碱和耐氧化性能 ，能在60℃以下，pH2-11的条件长期连续使用 。
Ultrafiltration is a separation process with separation as the driving force. The filtration precision is in the range of 0.005-0.01 um, which can effectively remove the microparticles, colloids, bacteria, heat and macromolecule organic substances in water. Can be widely used in the separation of substances, enrichment, purification. Ultrafiltration process without phase conversion, operating at room temperature, the separation of heat-sensitive substances is particularly appropriate, and has good temperature, acid and alkali and oxidation resistance, can be below 60 ℃, pH2-11 conditions for long-term continuous use.
