Study of Selecting RO Scale Inhibitors Based on the Conductivity Titration Curves

Article Preview

Abstract:

This paper discusses a selecting method of Reserve Osmosis (RO) scale inhibitors, which is fast and convenient. Five kinds of RO scale inhibitors (A-E) are used to explore the feasibility of the method, drawing their conductivity titration curves to evaluate their properties. The results show that, using the rapidly-dropping point of the conductivity titration curves to select the RO scale inhibitors can illustrate the preferential order of the scale inhibiting properties is B≈E>D>C>A.
