Transmembrane pressure

Membrane fouling is universally accepted as one of the critical problems limiting the wider application of membranes in liquid–solid separation. The in-situ ultrasonic application is one of the promising methods for reducing the extent of concentration polarization and increasing permeate flux durin

Among the membrane processes, membrane bioreactor (MBR) technologies are becoming an innovative and promising option for wastewater treatment and reuse. In this study the performance of the submerged membrane bioreactor was studied with an addition of MPE50, and it was compared against a sponge subm

Concentration and purification of lignosulphonates (LS) present in spent sulfite liquor (SSL) obtained from the paper industry were carried out through ultrafiltration (UF). The salts of lignosulphonic acid, a product of acid hydrolysis of lignin, are a major component of technical LS. In respect of

This article deals with water removal from oil-in-water emulsion by an ultrafiltration membrane at different transmembrane pressures. The membrane intrinsic resistance and gel resistance are analyzed and determined based on the resistance-in-series theory. The experimental results show that the effe

Collaborative work between Thames Water Utilities and PCI–Leopold outlines how pilot trial work has been taken through to full-scale application of a 9 Ml/d, ultrafiltration plant on a “significant risk” Cryptosporidium groundwater source. The pilot plant was subjected to a wide range of feed water
