  • A history of chemically resistant membranes

    The use of polymeric membranes for filtration of non-aqueous solutions started around 1960 and has been developed significantly since then [1]. Today, non-aqueous membrane filtration applications in chemical and pharmaceutical processing account for more than 25% of the global total polymeric membrane market [2]. ...

  • Focus on Microfiltration Part 3: Extending Service Life Using Prefiltration

    Last month we examined filter selection strategies for maximizing service life in continuous use applications.  In this 3rd installment, we will examine the use of prefilters to extend service life. Clarifying liquids with high levels of suspended solids is challenging, especially for applications requiring submicron filtration.  In these applications, filter users who experience ...

  • CSM fouling resistant reverse osmosis membranes

    This paper particularly deals with new fouling resistant RO membranes which are made more hydrophilic and less changed or charged with the same charge as the foulants to reduce hydrophobic interaction and charge attraction or to increase charge repulsion, respectively. The fouling resistant membranes manufactured by Woongjin Chemical in Korea are coated with hydrophilic monomers followed by ...

  • Fast-Set Polyurea HT 100F: Concrete Waterproofing for Foundations and Walls

    POLYSHIELD HT 100F is a fast-set, high performance, spray-applied, plural component, pure polyurea elastomer. This system is based on amine-terminated polyether resins, amine chain extenders, and prepolymers. It provides a cost effective flexible, tough, resilient monolithic membrane with water and chemical resistance. For more information about POLYSHIELD HT 100F, ...

  • Degreasing Liquid Treatment

    Degreasing is a necessary step before any other processing in mechanical industry, in the steel industry and generally speaking in the transformation of raw materials.  Degreasing is performed with aid of an aqueous solution containing detergents. The detergents emulsify oil present on the material to be treated; for this reason, oil concentration tends to increase in  ...

  • Effect of membrane characteristics on the performance of membrane bioreactors for oily wastewater treatment

    Influence of membrane material and pore size on the performance of a submerged membrane bioreactor (sMBR) for oily wastewater treatment was investigated. The sMBR had a working volume of about 19 L with flat sheet modules at the same hydrodynamic conditions. Five types of micro- and ultra-polymeric membranes containing cellulose acetate (CA), cellulose nitrate (CN), polyamide (PA), polyvinylidene ...
