... plant can be designed. Under varying throughput operation, a high aeration rate is required to generate a high crossflow velocity to minimize fouling. At low flow rates, a low aeration rate is used to minimize energy consumption. The aim of this work is to explore the feasibility of designing... consumption. The aim of this work is to explore the feasibility of designing smaller membrane plants by varying the throughput. This requires the control of membrane fouling, so that chemical cleaning is not compromised. Fouling is controlled by limiting the membrane flux and also by flushing th ...

Nanofiltration and adsorption on powdered adsorbent as process combination for the treatment of severely contaminated waste water
... from the concentrate subsequently by a thickener. The powdered adsorbent in the feed has a positive effect on permeate quality, permeate flux and fouling layer in the nanofiltration (NF) unit. Experiments with a semi-continuous pilot plant and biologically pre-treated landfill leachate have shown... still below the legal standards.

MBR functioning under steady and unsteady state conditions. Impact on performances and membrane fouling dynamics
Air was injected below each membrane module, ensuring vertical air lift circulation. To point out the role of the air membrane on membrane fouling control, different air flow rates were practised (1.36 m3.m–2.L–1 and 0.45 respectively for M1 and M2). Results confirm the high capacity o ...

... at least 100 times higher) than the conventional microfiltration. This extremely high fluxes causes the microsieves to be extremely susceptible to fouling and flux decline during filtration. As such, a new operating technique, i.e. high frequency backpulsing is introduced to keep the microsieve... from FluXXion B.V., to create backpulses at very high frequencies has been discussed. The impact of high frequency backpulsing on fouling control produced using the DCP technology has been studied with feed comprising only particulate foulants (latex suspensions), only nonparticulat ...
