Regulations

The US water quality requirements determine membrane selection. Many of the regulatory constraints for drinking water can be related to control of inorganic, organic or pathogenic solutes in the finished product. The specific application of membrane processes to drinking water applications is shown in simplified format in Table 2. The word Yes indicates the membrane process can remove significant amounts of contaminate specified by the rule, and No indicates the membrane process can not remove the regulated contaminate.
