  • Advanced treatment of WWTP effluent with filtration leading to a pretreatment technique for membrane filtration

    In 2000 the European Union introduced the Water Framework Directive (WFD). The aim of the WFD is having an ecological and chemical balance for all surface waters in Europe in 2015. The European Commission identified 33 priority substances and their maximum allowable concentrations, FHI-values (Fraunhofer Institute), which are specified in the Annex of the WFD. The objective of this research is to ...

  • A brief history of water filtration/sedimentation

    For millennia the search for ‘pure’ water has been pursued by humans. Criteria for purity have become more complex, more rigid, and more quantitative over time; however, the principles, methods, and material for purifying water have remained remarkably similar from the earliest recorded information of 2000 BC. The scope of this paper is to present a brief history of water ...

  • Use of Soil Filtration and UV Disinfection for Advanced Wastewater Treatment

    Abstract While guidelines exist, currently there are no federal regulations governing treatment requirements for reclaimed water. In their absence, many states have adopted California’s reclaimed water regulations, found under Title 22 of the California Code of Regulations (CCR) as well as the UV Disinfection Guidelines for Water and Water Reuse, published by the National Water Research ...

  • Treatment of leather industrial wastewater via combined advanced oxidation and membrane filtration

    The liming/unhairing operation is among the important processes of the leather industry. It generates large amounts of effluent that are highly loaded with organic hazard wastes. Such effluent is considered one of the most obnoxious materials in the leather industry, causing serious environmental pollution and health risks. The effluent is characterized by high concentrations of the pollution ...

  • Water filtration media: Talking about a revolution?

    Developments in any field of endeavour are nearly always evolutionary, not revolutionary. It is normal to expect advances in manufacturing equipment, process control and chemical science to facilitate product improvements. In the field of liquid filtration there is frustration at the seemingly unbreakable linkage that exists between increasing pressure drop and lower flow rates as gains are made ...

  • Advanced Water Treatment Solutions for the Food/Beverage Industry

    The agricultural/irrigation industry is one of the most demanding users of water for process applications. The availability of a sustainable supply of clean water is a necessity. Water shortages, reduction of water quality, and environmental issues, have led to an increased awareness of the use of both treated waste water as well as the ...

  • High-speed filtration using highly porous fiber media for advanced and compact particle removal

    Since its recent introduction to the filtration industry, one of the major concerns about the use of fiber in water treatment has been its applicability for high-rate filtration while minimizing the build-up of headloss. In this study, a compact, modular filter employing non-woven, highly porous polypropylene fiber as filter media was investigated for the treatment of turbid water under high ...

  • Advanced Water Treatment Technologies May Bring Purified Water to San Diego

    'In four years, half of San Diego may be filling its glasses with tap water that once ran through its toilets,' reported the San Diego Union-Tribune recently. A plan to mix 'repurified water' with the City's raw drinking water reservoir could become a reality, thanks to the wonders of water treatment technology. Such a possibility elicits various reactions including disgust, marvel and fear. ...

  • Micro Media Filtration Proving Effective in Produced Water Softening Systems

    Having an eff ective, durable pretreatment system in advance of ion exchange produced-water softening systems is the fi rst, most critical line of defense – ensuring smooth, more troublefree performance downstream. It’s especially true when dealing with today’s ion exchange technologies, which require TSS (total suspended solids) of 0.1-0.5 mg/L and turbidities of 0.1-1 NTU ...
