Abstract The reuse of activated carbon filter backwash water was performed using an ultrafiltration (UF) system and the membrane fouling mechanism was investigated using a model involving XDLVO theory and hydrodynamic interaction. Pretreatment by micro-flocculation/sedimentation removed most particulate pollutants; thus, residual organic colloids determined the details of the UF membrane fouling. The membrane fouling was divided into two periods. Membrane fouling in the initial period was determined by interfacial forces between the membrane and colloids. The calculated interfacial forces showed that permeation drag (PD) force dominated the total interfacial force at long-range, while London-van der Waals and short-range Lewis acid-base (AB) forces governed membrane fouling at short-range (

利用超滤回收活性炭过滤器反冲洗水：不同主导界面力引起的膜污染

摘要 活性炭过滤器反冲洗水的再利用使用超滤（UF）系统进行，并使用涉及XDLVO理论和水动力相互作用的模型研究膜污染机理。微絮凝/沉淀预处理去除大部分颗粒污染物；因此，残留的有机胶体决定了超滤膜污染的细节。膜污染分为两个时期。初始阶段的膜污染是由膜和胶体之间的界面力决定的。计算的界面力表明，渗透阻力 (PD) 力在远距离控制总界面力，而伦敦范德华力和短距离路易斯酸碱 (AB) 力在短距离控制膜污染。
