Abstract:

Ultrafiltration of B reservoir(near Harbin in China) water has been investigated. Using coagulation before UF not only increases the permeate flux, but also retards the permeability decline. Membrane filtration offers lower coagulant needed and good quality of produced water, compared to conventional water treatment. As for B reservoir water, 0.1% citric acid is a proper cleaning solution.

Key words: reservoir water, ultrafiltration, tap water, backwashing

摘要：

超滤膜过滤哈尔滨附近B水库水研究显示,超滤膜通量下降受膜进水浊度影响很大。利用混凝作为超滤的预处理能提高膜通量,并且能减缓膜通量的下降,混凝/超滤工艺所需混凝剂量比自来水厂常规工艺少,并且出水水质好。对于B水库水质量分数0.1%的柠檬酸溶液是较好的膜清洗剂。
