Study of Screening Reverse Osmosis Menmbrane Anti-Scaltants by Drainage Gradient Method

Abstract:

The aim of this paper is to elucidate the drainage gradient method's feasibility in evaluating and screening anti-scaltants. Nine different anti-scalants were selected as research object, the results show that KCa、KJD、pH and Langelier's saturation index (LSI) can be used as indicators and KJD、pH are more sutible indicators.with the relative standard deviations (RSD) of repeated experiments were from 0.24% to 3.04%, the drainage gradient method has good repeatability.
