  • Case study - Rubber curing emissions

    Overview A rubber curing company was looking for a new, affordable abatement solution to treat their blue haze and low-level Volatile Organic Compounds (VOCs) in order to meet regulatory requirements. The large Electrostatic Precipitator (ESP) in use was extremely expensive to operate and maintain. The company began their search for a system that offered effective opacity control and ...

  • Building a filter defense against Zebra and Quagga mussles

    Tiny mussels can create massive problems for intake structures, vaLves, pumps, screens and other water infrastructure around the US. Some filtration systems can provide chemical-free protection against invasive zebra and quagga mussels, but it is vital to understand the problem and develop the right system to avoid being overrun by the alien species. Zebra mussels (Dreissena polymorpha) and their ...

  • Case study - Organic particulate filtration

    Overview A food products company that mixes various types of waxes and other components to make the base for chewing gums was faced with the issue of cleaning up a slightly odorous, visible emission being exhausted from two of their process lines. The components of the emission were hot particles of chewing gum and some volatile organic compounds (VOC's). The particles would quickly clog ...

  • Smoke Factory Chooses Automatic Self Cleaning Filter for Efficient and Effective Chiller Protection

    BACKGROUND Cooling towers dissipate both ambient and process heat in most large manufacturing facilities.  These structures facilitate the transfer of unwanted energy (heat) from a transport liquid (usually water) to the atmosphere.  Problems with efficient heat transfer, equipment protection and pathological risks to employees can most often be traced back to an issue with suspended ...

  • AMIAD’s Filtomat Microfiber for RO Pre-Treatment

    In this feature article, we outline the effectiveness of Amiad Filtomat Microfiber automatic self cleaning filter technology when used in reverse osmosis (RO) pretreatment for the production of potable water. The Filtomat provides effective prefiltration of various water sources prior to RO. We examine how the pre-filtration technology operates and how it can be integrated into a RO system. We ...

  • Amiad’s AMF² pre-treatment technology ensures efficient and reliable nanofiltration of Scottish Highland loch water

    In this feature article we report on the effectiveness of Amiad’s AMF² automatic self cleaning filter technology as a pre-treatment for membrane systems. We focus on high and variable suspended solids and colour removal applications where potable quality water is required from nanofiltration (NF) systems. We show how the AMF² units provideeffective pre-filtration of Scottish Highland loch water ...

  • Stormwater Solids Reduction for NPDES Permits

    Finally obtaining a National Pollution Discharge Elimination System (NPDES) Permit is often a relief but is by far not the end of the story. Meeting the requirements of that permit often proves to be quite difficult and stiff fines are freely doled out to those who fail to meet regulatory limits. For one Midwest jet propulsion manufacturing facility, the issue of total daily solids discharge ...

  • 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 ...

  • 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 ...

  • Efficient Removal of Organic and Inorganic Suspended Solids

    ABSTRACT The Romans used sand as a filter media to treat their drinking water 2000 years ago. Centuries ago water was poured through layers of cloth to remove visible impurities in drinking water with fabric bags and paper cartridges soon following. Darcy employed sand beds in Dijon, France over 200 years ago to conduct his experiments for developing his famous equation to describe fluid flow ...

  • 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 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. ...

  • Screen Filtration Technology as Applied to Pretreatment of Reverse Osmosis and Ultra-Filtration Systems

    Summary New developments in the manufacturing technology of stainless steel weavewire screens enable mechanical style self-cleaning filters to be utilized as the primary pretreatment device for R-O and U-F systems. These systems are more cost effective and feature lower O&M requirements, than multimedia ...
