Abstract

A reliable and rapid laboratory procedure was developed for rapid screening of reverse osmosis (RO) membrane anti-scalants and compared with existing laboratory methods. This laboratory procedure consists of two parts according to the characteristics of screening RO membrane anti-scalants: preliminary screening of anti-scalants by static method and further by dynamic methods based on the result of static method. Conductivity method, critical pH method and turbidity method were selected as the methods for preliminary screening of RO anti-scalants, and drainage gradient method and dose gradient method were chosen as the dynamic methods for further screening RO anti-scalants.
