Drinking Water Filtration Case Studies and White Papers

  1. Desalinating Brackish Groundwater Eases Water Shortage
    4/23/2018

    The city of Limassol in Cyprus was experiencing an increasingly severe water shortage, with the growing population and expanding tourist industry placing extra pressure on existing supply. An aquifer in a residential neighborhood was seen as a potential water source, but had high levels of salts and nitrates. The Cyprus Water Development Department (WDD) awarded Fluence a Build-Own-Transfer (BOT) contract to implement a cost-effective solution.

  2. Addressing Fouling Challenges In Water Treatment With RO Membrane
    4/18/2018

    Reverse osmosis (RO) membranes are widely used in potable water, wastewater, and industrial applications. However, a major issue in the application of RO membrane technology for desalination and wastewater reclamation is membrane fouling. It limits operating flux, decreases water production, and increases power consumption. Membrane fouling also increases the need for RO plants to perform periodical membrane CIP procedure. These problems decrease process efficiency, increase operation cost, and raise environmental issues related to the CIP solutions disposal.

  3. Harmful Algae: How To Stay Ahead Of The Bloom
    3/20/2018

    It’s the call no water treatment plant superintendent wants to receive, especially not while on vacation. Andy McClure, Superintendent of Toledo, Ohio’s Collins Park Water Treatment Plant, answered his phone to hear his head of operations report that the level of microcystin in the finished water was high, caused by a large harmful algal bloom (HAB) that was impacting the plant’s Lake Erie intake.

  4. Membrane Module Pilot Test In North Dakota
    10/11/2017

    Toray UF membrane modules were piloted over a fifteen-week period to help service the growing demand for clean water in southwest North Dakota. The outcome, as part of the Southwest Pipeline Project (SWPP), would be construction of the Oliver-Mercer-North Dunn (OMND) Water Treatment Plant.

  5. Integrated Membrane Facility In The City Of Delaware, Ohio
    10/11/2017

    To better comply with the Long Term 2 Enhanced Surface Water Treatment Rule (LT2) the City of Delaware (Ohio) piloted Torayfil hollow-fiber PVDF membrane modules to treat surface water for their 7.2 mgd full-scale facility. After significant review of the data, cost, and other factors, the City and URS selected Toray to utilize in the full scale design. Read the full case study to learn more.

  6. Ecomuseum Zoo: High Efficiency Filtration Reduces Turbidity & Maintenance Costs
    9/12/2017

    ​The Ecomuseum Zoo is home to the most impressive ambassadors of Quebec’s wildlife. All residents of the Ecomuseum Zoo are there for a special reason: orphaned, injured or born under professional human care, each of them could not return to the wild. Hence, they have found a forever home at the zoo.

  7. Bubble Removal From Aqueous Streams Using 3M™ Liqui-Cel™ SP Series Membrane Contactors
    7/18/2017

    Many manufacturing processes, analytical measurements, and other industrial processes that involve aqueous solutions are adversely affected by bubbles in the fluid stream. 3M™ Liqui-Cel™ SP Series Membrane Contactors provide a very simple, cost effective solution to help eliminate bubbles from such processes.

  8. Degassing Boiler Feed Water in China with 3M™ Liqui-Cel™ Membrane Contactors
    7/6/2017

    ShenLan Environment Inc. located in Shanghai, China uses 3M™ Liqui-Cel™ Membrane Contactors in their boiler feed water treatment systems. These systems realize lower operating costs with the added benefit of reducing the chemicals added to the boiler feed water.

  9. Using ‘TransMembraneChemiSorption’ (TMCS) For Ammonia Removal From Industrial Waste Waters
    7/4/2017

    Dissolved gases like NH3, H2S or NOx in waste water lead to contamination in the sewage system and high treatment costs for municipal waste water treatment plants. 

  10. 3M™ Liqui-Cel™ Membrane Contactors Improve Water Quality and EDI Performance
    6/27/2017

    Electrodeionization (EDI) is a widely used water treatment process. EDI technology is an electrochemical process that uses ion selective membranes and an electrical current to continuously remove ions from water. The process uses ion exchange resin to remove the ions from the feed stream, producing pure water.
