Integrated membrane system

A pilot-scale ultrafiltration (UF)–nanofiltration (NF) integrated membrane system (IMS) which included a selfcleaning crossflow UF filtration process and a dual-stage NF process with a capacity of 100 m3·d−1 NF permeation water was established for seawater softening investigation. The separation perform

This study explored the effect of increasing nanofiltration (NF) permeate recovery (RNF) by recirculation and dosage of chemicals on NF separation performance, concentration polarization (CP) and accumulation of scalingprone ion concentration on NF membrane surface. The related coupling effect on sea
