Chemical cleaning

Ceramic ultrafiltration membranes were used to treat desizing wastewater for recycling. Both the fouling mechanisms and the regeneration of fouled membranes obtained from an industrial park were studied. The fouling was mainly caused by polymethyl acrylate (PMA) deposition on membrane surface and blo

Membrane separation technologies applied to protein purification is an interesting development that has seen growth in recent years. However, studies about the long-term effects of the cleaning stage, considering different chemical agents and operating conditions, on the performance of the membranes

Membrane technology has experienced an important development in the last years, being more and more employed as an alternative to conventional separation processes. However, the investment due to purchase and replacement of membranes in industrial plants is still a very significant cost. Therefore,

Fouling remains a major issue for all membrane applications. This study investigated anti-fouling applications for a side-stream membrane bioreactor (MBR) fed with glucose-based synthetic wastewater. Air sparging, backflushing and high cross flow velocity (CFV) were investigated as anti-fouling stra

Ultrafiltration of Binxian reservoir (near Harbin in China) water to produce drinking water was investigated in this study. Membrane flux declined with temperature coming down. Using coagulation before UF not only increases the permeate flux, but also retards the permeability decline. In comparison

In this paper the results obtained from investigations on a polyamide reverse osmosis membrane fouled by precipitation of materials which exist in water are presented. In these studies, the effect of different cleaning agents on recovery of the fouled membrane has been shown. Results show that a com
