  • VSEP replaces crossflow membrane systems, filtering industrial wastewater at pulp and paper mills

    Technological advances in membrane filtration systems have created an opportunity for pulp and paper mills to treat effluent streams in order to meet stricter environmental constraints. “Vibratory Shear Enhanced Processing” or VSEPÔ, developed by New Logic International makes it possible to filter effluent streams without the fouling problems exhibited by conventional membrane systems. The VSEP ...

  • VSEP helps meet discharge guidelines, recycles water and improves mine economics

    Since their development as lab filters in the early 1960s, polymeric membranes have grown in the number of uses at exponential rates. Membrane architecture and process design itself has undergone significant advancement. A unique membrane filtration system, known as V✧SEP (Vibratory Shear Enhanced Process), was developed by New Logic of Emeryville California. The technology employs ...

  • Affinity adsorption for the removal of organic micropollutants in drinking water sources; proof of principle

    Sources for drinking water (DW) production contain increasing concentrations of organic micropollutants, such as pesticides and pharmaceuticals. Traditional purification processes are not suitable for their removal or conversion, but even sophisticated technologies, like advanced oxidation processes and membrane filtration, are not able to efficiently remove all compounds from DW. For ...

  • Cost comparison of full-scale water reclamation technologies with an emphasis on membrane bioreactors

    The paper assesses the costs of full-scale membrane bioreactors (MBRs). Capital expenditures (CAPEX) and operating expenses (OPEX) of Spanish MBR facilities have been verified and compared to activated sludge plants (CAS) using water reclamation treatment (both conventional and advanced). Spanish MBR facilities require a production of 0.6 to 1.2 kWh per m3, while extended aeration (EA) and ...

  • 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 ...

  • Pharmaceutical removal during managed aquifer recharge with pretreatment by advanced oxidation

    Organic micropollutants (OMPs) are detected in sources for drinking water and treatment possibilities are investigated. Innovative removal technologies are available such as membrane filtration and advanced oxidation, but also biological treatment should be considered. By combining an advanced oxidation process with managed aquifer recharge (MAR), two complementary processes are expected to ...

  • Pre-coagulation and ultrafiltration of effluent impaired surface water for phosphorus removal and fouling control

    The process combination of in-line coagulation and subsequent membrane filtration is a suitable advanced treatment stage to achieve higher quality standards regarding pathogens and phosphorus in biologically treated wastewater prior to its discharge into sensitive water bodies. In this study a membrane pilot installation (capacity of 6 m3/h) was operated in dead-end configuration to investigate ...

  • Sohar Refinery

    Project Background Orpic (Oman Oil Refineries and Petroleum Industries Company) required a thermal seawater desalination solution as part of its Sohar refinery improvement project to ensure an uninterrupted supply of fresh feed water to for its boilers. ...

  • Top 5 benefits of wastewater treatment for pharmaceutical industries

    Waste waters are generated as the outcomes of various processes like chemical synthesis, fermentation, etc in a pharmaceutical industry. Hence, wastewater treatment has become mandatory for these industries to maintain the optimum quality. Moreover, such treatments are inevitable for the companies to meet the desired legal standards in pharmaceutical production. Violating such requirements can ...

  • Why Current Water Treatment Technology Can`t Solve The Global Water Crisis

    Summary GE, Veolia, Dow and American Water Works are selling billions in water treatment technology. All their water treatment technologies work or they wouldn't be selling. In spite of effective water treatment technologies, the global water crisis persists. The problem is the high cost of current ...

  • Water Reuse Terminology

    All water on Earth is used and reused, over and over, in an elegant water cycle. Water reuse occurs in various ways on a daily basis. It happens when a community’s treated wastewater is discharged into rivers or other water bodies. If you live in a community downstream of another, chances are you are reusing water from an upstream town. Scientifically proven advances in water technology ...
