Abstract

This paper utilizes the conductivity method, critical pH method and turbidity measurement to select RO scale inhibitors. Six kinds of RO scale inhibitors both at home and abroad are used to explore feasibility of the three methods. The results show that, all of them can be the rapid screening methods for scale inhibitors; test temperature and dosage of inhibitor affect screening results. The total weighted mean value is suggested to evaluate RO scale inhibitors. And the relative standard deviation (RSD) of the conductivity method, critical pH method and turbidity measurement are 1.92%, 0.57% and 55.23% respectively.
