The optimized operating condition obtained at pH 11.1, and a ratio of [CO32-]:[Ca2+]=1.2:1 enabled to obtain 90% efficiency of calcium removal from real water. The efficiency of scaling potential removal was validated by comparing the scaling level on the membrane surface of two electrodialysis batches of a washing water, with and without pretreatment. For the latter, scalants were found at both sides of the cation exchange membrane (FKB), diluate and base sides, identified as calcium and magnesium precipitates. Furthermore, there was also a severe scaling effect at the base side of the bipolar membrane (FBM). However, a different observation was found for the pretreated water. SEM and elemental analysis for both FKB and FBM membranes demonstrated less scaling on both membrane surfaces. 2014-06-17T08:20:31Z 2014-06-17T08:20:31Z 2013-07 Article Journal of Colloid and Interface Science, vol. 401, 2013, pages 107-115 0021-9797 http://www.sciencedirect.com/science/article/pii/S0021979713002816 http://dspace.unimap.edu.my:80/dspace/handle/123456789/35605 en Elsevier Inc.
