  • Membrane foulants and fouling mechanisms in microfiltration and ultrafiltration of an activated sludge effluent

    Membrane fouling in microfiltration (MF) and ultrafiltration (UF) of an activated sludge (AS) effluent was investigated. It was found that the major membrane foulants were polysaccharides, proteins, polysaccharide-like and protein-like materials and humic substances. MF fouling by the raw effluent was governed by pore adsorption of particles smaller than the pores during the first 30 minutes of ...

  • Respirometric assays of two different MBR (microfiltration and ultrafiltration) to obtain kinetic and stoichiometric parameters

    A comparison of two different medium scale MBRs (ultrafiltration and microfiltration) using respirometric methods has been achieved. The ultrafiltration membrane plant (0.034 µm pore size) maintained recirculation sludge flow at seven times the influent flow, and membranes were backwashed every 5 min and chemically cleaned weekly. The microfiltration membrane plant (0.4 µm pore size) maintained ...

  • Analyzing the spatial and temporal characteristics of membrane fouling

    Fouling characteristics of crossflow flat-sheet membranes for two Nanofiltration (NF), one Ultrafiltration (UF), and one Microfiltration (MF) membranes were analyzed using 12.5 parts per million (mg/L) FeCl3 solution and 350 mg/L copper nanofluid. FeCl3 solution represents dissolved contaminant whereas copper nanofluid simulates particulate contaminant. The spatial and temporal fouling ...

  • Validation of the Goreangab Reclamation Plant in Windhoek, Namibia against the 2008 Australian Guidelines for Water Recycling

    Australia has had Guidelines in place for water recycling (for all uses other than the augmentation of drinking water supplies) since 2006. These Guidelines were extended to cover potable reuse in May 2008 and have been applied to two potable reuse projects in Australia – one a trial plant in Perth, Western Australia and the second for a large AUD$2.6 × 109 scheme in ...

  • Evaluating Spiral-wound Separator Performance

    Introduction The recent evolution of spiral-wound membrane element (sepralator) design brings an increased need to understand the intricacies of testing, operating and predicting performance of this most popular crossflow membrane design. After over a decade of stagnant development, the last five years have produced several innovations, which diversify and expand the applications as well as ...


  • Treating Industrial Water with Membrane Technology

    A variety of industries are finding that it makes sense to reevaluate the way they treat industrial process water, both to improve the quality of their products and increase the efficiency of their processes. Purification systems utilizing crossflow membrane filtration, such as reverse osmosis (RO), nanofiltration (NF) or ultrafiltration (UF) can be a good alternative to traditional filtration ...


  • Using Nanofiltration in Beverage Production

    The following article is based on a paper presented in August, 1990 at the 21st Annual Meeting of the Fine Particle Society in San Diego. Soft drink manufacturers, not to mention manufacturers of other beverage products, have always had a keen interest in the water that goes into their products. After all, it is the water that typically makes up 80%-90% of the product. In the past the water has ...
