The Doran catchment (at an altitude of more than 1500 m) is the main resource of Sallanches. It is subject to wide variations in turbidity without a conjugate change in other parameters.
Direct treatment by Ultrafiltration membrane was used.

A power plant in Buenos Aires needed to increase its demineralized water production and save money on operating expenses, but the poor quality of the available raw water from a nearby river made it difficult to make the switch from ion exchange technology to reverse osmosis (RO).
This case study shows...
A novel thin film composite (TFC) polyamide reverse osmosis membrane was prepared via the interfacial polymerization of m-phenylene diamine (MPD) in aqueous phase and 1,3,5-trimesoyl chloride (TMC) in organic phase on a polysulfone ultrafiltration support by assisting with ethyl formate as a co-solvent added in the organic phase. The ethyl formate added in the organic phase is intended to form a narrow miscibility zone, which leads to the thicker reaction zone. The multi-layered loose polyamide structure with...
The aim of this study was to assess the efficacy and effluent quality of a pilot-scale intermittently aerated and fed, externally submerged membrane bioreactor (MBRes) treating municipal wastewater. The effluent quality of the MBRes was evaluated regarding system ability to comply with the Greek legislative limits for restricted and unrestricted wastewater reuse. The average permeate flux was 13.9 L m−2 h−1, while the transmembrane pressure remained above the level of −110 mbar. Experimental data showed that...
A novel material coating for water treatment membranes promises to improve the removal of water-borne viruses during treatment.This hydrogel coating, known as a zwitterionic polymer hydrogel, was created by scientists from Ben-Gurion University of the Negev and the University of Illinois at Urbana-Champaign.The virus-fighting membrane was created by grafting the new hydrogel coating onto the surface of commercial ultrafiltration membranes.The substance prevents viruses from both nearing and passing through the...
