Water Membranes White Papers and Case Studies

  1. Aqua MultiBore® C-Series Ceramic Membrane System Solves Disinfection By-Product (DPB) Challenge At Butte-Silver Bow, Montana 4/15/2019

    The Basin Creek Reservoir in Butte, MT served its community with pristine water from both sides of the Continental Divide for nearly 100 years. In 2010, a pine beetle infestation killed most of the trees surrounding the reservoir, many of which fell into the water, increasing the natural organic matter (NOM) level.

  2. Design And Care Of Reverse Osmosis Systems, Part 3: Operation And Monitoring 2/5/2019

    Reverse osmosis (RO) systems offer power plant owners and operators a reliable and well-proven water treatment solution. However, designing and caring for an RO system requires a thorough understanding of a plant’s water supply and the technology’s capabilities. The final article of this three-part series will address RO system operation and maintenance best practices.

  3. Is A Containerized Treatment System Right For You? 1/24/2019

    As industrial facilities continually look for ways to reduce capital costs and decrease installation timelines associated with water treatment and other systems, the practice of containerizing equipment has become more prevalent. A containerized system offers many benefits of lower costs than comparable field erected buildings, faster timelines, and lower field installation requirements. 

  4. Design And Care Of Reverse Osmosis Systems, Part 2: Upstream Equipment 1/14/2019

    The success of a new reverse osmosis (RO) membrane system is often directly related to its pretreatment. The previous section of this article discussed RO design issues and introduced how a pilot study should include a study of its probable pretreatment equipment since the pretreatment performance will directly affect the performance of the RO system. However, piloting the upstream processes can be challenging in sizing these components for the pilot RO unit’s low flow rate.

  5. Design And Care Of Reverse Osmosis Systems, Part 1: Design 12/20/2018

    Reverse osmosis (RO) systems offer power plant owners and operators a reliable and well-proven water treatment solution. However, designing and caring for an RO system requires a thorough understanding of a plant’s water supply and the technology’s capabilities. Part one of this series will review the importance of water samples and pilot studies as plant engineers begin to design an RO system to match their needs.

  6. Trouble In Paradise, And A Plan To Alleviate It 12/4/2018

    While San Diego has a reputation for beautiful weather in a sunny seaside setting, its growing population in the southernmost area of rain-starved California is a recipe for trouble in paradise. That challenge has spurred the creation of Pure Water San Diego — a multi-phase, multi-year program with the goal of using recycled water for up to one-third of San Diego’s water supply by the year 2035.

  7. Expansion And Upgrade Of WWTP Ozone Disinfection System Reduces Energy Cost By 69% 9/10/2018

    The financial cost to maintain their ozone equipment, and increasing scarcity of replacement parts for their ozone generator, motivated a utility in Springfield, MO, to upgrade their ozone system. Read the full case study to learn how the plant assessed the energy cost of a sidestream ozone injection system compared to that of a turbine mixing design and showed that the Mazzei retrofit design reduced the energy cost of ozone contacting by an average of 69.2% under all plant flow conditions.

  8. Largest Ozone Facility In North America Meets Regulatory Requirements And Remediates Taste & Odor Problems 9/5/2018

    The North Texas Metropolitan Water District began working to add ozone to its four interconnected water treatment facilities which operate as the Wylie Water Treatment Plant (WTP).

  9. Improving The Quality Of Tertiary Effluent For Indirect Potable Reuse With Geographic Constraints 9/5/2018

    The Mazzei Sidestream Venturi Injection – Pipeline Flash Reactor System provides a feasible alternative for dissolution of ozone at the Clark County Water Reclamation District (CCWRD) in Las Vegas, because it allowed for flexibility in basin design to meet geographic site constraints.

  10. Ozone Resolves Hydrogen Sulfide And Color Issues In Well Water 9/1/2018

    A potable water plant in Eastern Angelina County, Texas,  serves over 2,000 rural customers.
