  • 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 ...

  • Rold Model Water Recycling Program

    ABSTRACTThe Viejas Band of Kumeyaay Indians, a federally recognized tribe, vested with authority by the U.S. Environmental Protection Agency (USEPA), form the Tribal Government to regulate all activities concerning water quality issues within the reservation boundaries. The Reservation has 400 non-transient residents and an average of 5,000 transient residents. The transient population visits the ...

  • Water Reuse Alternatives in Southern New Jersey

    Water reclamation and reuse can be a valuable resource in cities or towns that are challenged by population growth, contamination of surface water and groundwater, uneven distribution of water resources, and frequent droughts caused by extreme global weather patterns. In addition to easing the strain on limited freshwater supplies, the reuse of wastewater can improve the quality of streams and ...

  • Salinity Impacts to Water Recycling in Southern California

    ABSTRACTIn 2000, U.S. Bureau of Reclamation (Reclamation) and twelve cost sharing partners began the Southern California Water Recycling Projects Initiative (Initiative), which is a multiyear planning study. This study was established to assist local agencies in their recycled water planning for specific projects as well as addressing regional issues that may influence water recycling in southern ...

  • Utilizing unconventional water sources for industrial reuse

    Reclamation and reuse of unconventional wastewater sources for plant raw water, cooling water and process pre-treatment has increased substantially due to increases in the cost of drinking water, recurring water shortages that can impact business operations, and tightening government regulation. Water is required in almost every industrial sector for the processing and manufacture of products. ...

  • Design and assessment of urban drainage and water reuse systems for the reconstruction of formerly industrial areas: a case in Beijing

    The Shougang Group is an industrial steel enterprise occupying 800 ha in Beijing that will cease production by 2010. The area will be converted to a new financial and commercial zone. The rebuilding of the water infrastructure in this area should address water shortages in Beijing and retain the industrial landmark of a large cooling water tank. A design framework and an assessment system with ...

  • Application of Membrane Technology for the Recovery and Reuse of Water

    Abstract As water and sewer costs are expected to increase over the next decade, membrane technology will continue to be a viable and economical option in the recovery and reuse of water. This paper describes the mechanism of membrane effected separation (specifically reverse osmosis, ultrafiltration and microfiltration), membranes commercially available, membrane element configurations, and how ...


  • Spiral-Wound Elements for Potable Water Treatment

    Introduction Any new technology must overcome perceptions of the marketplace, which are not accurate. As a technology moves into new areas of application, new misconceptions also arise. Crossflow membrane technology is no exception. The first man-made, pressure-driven 'crossflow' membranes were made in flat sheet form. This membrane had to be configured in a device, and was first made in ...


  • Diamonds, gold and the value of water: The impacts of mining in South Africa

    Starting today, Nick Tandi and Anton Earle from SIWI’s African Regional Centre, the 2030 Water Resources Group (2030 WRG) and the South African Ministry for Water will host a week-long knowledge exchange trip to Pretoria, South Africa. The knowledge exchange places emphasis on private sector engagement in multi-stakeholder partnerships related to mining and to finding solutions for water ...

  • Oil and Water Don’t Mix – But Can They Co-Exist? - A GLOBE-Net Editorial

    Real progress is being made to reduce the environmental impacts of oil sands activities. But that message is being lost in the flood of bad press about contamination of adjacent waterways and the concerns about those ugly tailings ponds. Oil and water do not mix. But can they co-exist? GLOBE-Net, September 1, 2010 - August has not been a good month for the Alberta oil sands industry. The tidal ...

  • Evaluation of a bench-scale membrane fouling protocol to determine fouling propensities of membranes during full-scale water reuse applications

    There is increasing interest in recycling wastewater effluents for augmentation of existing water supplies. The treatment of wastewater effluents by an integrated membrane system, such as microfiltration pre-treatment followed by reverse osmosis, is the industry standard for groundwater recharge or reservoir augmentation projects. Membrane fouling, especially effluent organic matter fouling, is a ...

  • What do oil sands and shale gas have in common? Acute need for sustainable water management solutions

    The world’s appetite for fossil fuels is not abating anytime soon, and the alternatives fall short. Nuclear energy makes people uneasy, coal is perceived as not being that clean, hydroelectric requires massive capital outlays, solar is still improving and the wind just doesn’t always blow. For the foreseeable future, North Americans have embraced the idea that expanded production of ...

  • The MIEX® Technology for Municipal Wastewater Treatment

    The MIEX® Technology is designed for the removal of dissolved organic carbon (DOC). Until recently, the commercial application of the MIEX® Technology has been limited the treatment of potable water from surface or ground water bodies. The MIEX® Process is now being evaluated for application in municipal wastewater applications. An example of this is the use of the MIEX® Process for the treatment ...
