  • Self-Cleaning Filters for Pretreatment of Membrane and UV Water Treatment Systems

    The removal of suspended solids is necessary to protect membrane systems and prevent the “shadow effect” in ultraviolet (UV) treatment systems. Recent field data has shown the effectiveness of automatic self-cleaning filters in removing suspended solids down to less than 3 microns in size without flocculants, pre-coats or granulated media. Tests have demonstrated the complete removal of particles ...

  • Self-Cleaning Pre-Filtration for RO Membrane Systems

    ABSTRACT A few years ago physical processes could only remove suspended solids from a water stream. Recent advances in technology now allow the removal of selected molecules and ions from a water stream by physical means using membranes. The membrane process has recently become very efficient and economically feasible for many industrial, commercial, municipal and even residential customers. ...

  • Removing Solids with Automatic Self-Cleaning Filters

    Introduction The “art” of filtration utilizes many methods for separating solid particles from fluids. There is often no right or wrong method. Water quality and customer requirements usually determine the “best” method for each unique situation. Ridged screens, pleated cartridges, string wound cartridges, melt blown cartridges, woven fabrics, non woven fabrics, sintered metals, granular ...

  • Self-Cleaning Pre-Filtration for RO and Other Membrane Systems

    Abstract A few years ago physical processes could only remove suspended solids from a water stream. Recent advances in technology now allow the removal of selected molecules and ions from a water stream by physical means using membranes. The membrane process has recently become very efficient and economically feasible for many industrial, commercial, municipal and even residential customers. ...

  • Self-Cleaning Filtration for Pretreatment of Membrane, UV and Ozone Water Treatment Systems

    Recent field data has shown the effectiveness of automatic self-cleaning filters in removing suspended solids down to less than 3 microns in size without flocculents, pre-coats or granulated media. Pre-treatment of ozone systems is often needed to remove organic solids that would utilize high amounts of ozone during oxidation leaving little for complete disinfection. Selfcleaning screen filters ...

  • A Membrane Pretreatment Technology

    Nearly all membrane systems, no matter what their raw water source, must utilize some form of pretreatment to remove unwanted organic and inorganic suspended solids. Bag and cartridge filters are efficient at removing suspended solids but must be replaced on a frequent and often costly basis. Some form of suspended solids removal system that cleans itself, maintains high flow rates and stays ...

  • Micro-90 Effective Filter Membrane Cleaner for Wastewater Treatment Operations

    The care and cleaning of filter membranes is essential to the success of many water treatment systems.  International Products Corporation (IPC) manufactures a line of membrane cleaners effective at restoring 100% flux at safe pH ranges.  One of IPC’s customers treats industrial wastewater generated by the engine plant of a major automotive ...

  • Air filtration applications for membranes

    Given their unique performance attributes membranes are finding use in a growing number of high efficiency air filtration applications. One example is in respirators and personal protective equipment. Applications where intense physical demands and risk of exposure to harmful contaminants are present demand the high efficiency / low pressure drop combination of expanded polytetrafluoroethylene ...

  • 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 ...


  • Comparison of NF membrane fouling and cleaning by two pretreatment strategies for the advanced treatment of antibiotic production wastewater

    The nanofiltration (NF) membrane fouling characteristics and cleaning strategies were investigated and compared for treating membrane bioreactor (MBR) effluent and MBR-granular activated carbon (GAC) effluent of an antibiotic production wastewater by DK membrane. Results showed that the fouling of treating MBR effluent was more severe than that of treating MBR-GAC effluent. After filtering for ...

  • Dynamic Mathematical Modeling of Membrane Fouling in Submerged Membrane Bioreactors

    ABSTRACTA mathematical model is developed that accounts for internal fouling of membranes due to soluble microbial products during subcritical flux operation, and for supercritical flux fouling due to cake formation and compression.. The model takes into account the filtration effect generated by the cake. A set of differential equations is derived and solved numerically to obtain a description ...

  • Indestructible Pumps for Clean Water

    Sulzer pumps are used in the production of drinking water in many cities around the world. The special qualities that these pumps possess can be seen at the Zurich Municipal Water Utility. There, the operators have to cope with rising land and energy prices and a challenging topography. A small water flea plays a major role in Zurich. It swims around in a container of drinking water with some of ...

  • Coming Clean with the Environment

    Long Island is a long, slender island located directly east of Manhattan in the southern tip of New York State. In the 20th century, the north shore of Long Island earned the nickname of “Gold Coast” and attracted large private estates of the likes of the Vanderbilts, Roosevelts, Whitneys, Charles Pratt, J. P. Morgan, F. W. Woolworth, and others. The western end of the island includes ...
