Membrane Fouling Alleviation by Chemically Enhanced Backwashing in Treating Algae-Containing SurfaceWater: From Bench-Scale to Full-Scale Application Article

Xiaobin Tang, Tiecheng Guo, Haiqing Chang, Xiao Yue, Jinlong Wang, Haikuan Yu, Binghan Xie, Xuewu Zhu, Guibai Li, Heng Liang

Engineering 2022, Volume 19, Issue 12,   Pages 40-49 doi: 10.1016/j.eng.2021.01.013

Abstract:

Ultrafiltration (UF) has been increasingly implemented in drinking water treatment plants; however, algae and their secretions can cause severe membrane fouling and pose great challenges to UF in practiceof oxidization, thereby weakening the cohesive forces between the organic foulants and the membrane surfaceconsumption, and is proposed as an alternative to control membrane fouling in treating the algae-containingsurface water.
