专家说需要对每种污染物进行测试,以查明对人类的长期影响。
High purity water systems are primarily composed of austenitic stainless steel (ss) materials due to their corrosion resistant and contaminant free properties.考虑到铬镍不锈钢(SS)的抗腐蚀和防污染性,高纯水系统基本上都是由铬镍不锈钢材料构成。
Each of the membrane technologies is essentially a filtration process in which contaminant ions are filtered from solution using a membrane with very small water passages.这些膜技术本质上都是一个过滤程序,就是用一个有非常细小水通道的膜片把污染物离子从溶液里过滤掉。
