Fouling control

This paper presents MBR performances observed under steady and unsteady state conditions where influent and permeate flow rates were punctually and simultaneously increased. Experiments were performed in a submerged membrane bioreactor presenting a 50 L working volume. Two capillary membrane modules

Silicon nitride microsieves are microfiltration membranes manufactured with techniques commonly used in the semi-conductor industry for wafer production. These membranes are characterised by the uniform pore size and the high porosity. Furthermore, due to their extremely thin selective layer and the

Membrane bioreactors (MBRs) have been used increasingly for municipal wastewater treatment. The current wastewater treatment plants are designed to treat three times the average flow in dry weather (DWF) which covers the expected range of incoming flow rates. If throughput in MBRs can be changed rea

A new process combination for the treatment of severely contaminated waste water has been developed: powdered adsorbent is injected into the feed of a nanofiltration unit and removed from the concentrate subsequently by a thickener. The powdered adsorbent in the feed has a positive effect on permeat
