Water Membranes White Papers and Case Studies

  1. China Power Plant Reduces Capital Costs, Energy Use With New Integrated Membrane System
    6/15/2017

    As engineers come under increasing pressure to reduce maintenance and operating costs, inefficient combination double-pass reverse osmosis and electrodeionization (RO/EDI) water treatment systems have begun to lose popularity as a means of providing ultra-pure water. Integrated membrane systems (IMS), on the other hand, combine multiple membrane-based water treatment processes into a single system. In this case study, find out how a heat and power plant in Northeast China lowered capital costs and energy use by adopting an IMS to replace its conventional water treatment system.

  2. IMEC UPW System Utilizes 3M™ Liqui-Cel™ Membrane Contactors For Oxygen Removal
    5/4/2017

    IMEC (Interuniversity Micro- Electronics Center) in Belgium is Europe's largest independent research center. It focuses on microelectronics, nanotechnology, and enabling design methods and technologies for ICT (Integrated Circuit Technology) systems. IMEC's research runs 3 to 10 years ahead of industrial needs.

  3. Ozone Resolves Hydrogen Sulfide And Color Issues In Well Water
    4/27/2017

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

  4. Evaluation And Optimization Of Clean-In-Place Using Ozone
    4/27/2017

    A chemical company which specializes in Clean-In-Place (CIP) systems, contacted Mazzei to discuss the use of ozone as an alternative to peracetic acid sanitation or heat sterilization at their customers’ plants.

  5. Basin Nozzle Manifold Contacting System Installation Remediates Taste And Odor Compounds, Meets Disinfection Goals
    4/27/2017

    A water quality audit revealed that two of the largest drinking water plants in the City of Montreal were out of compliance with Quebec’s latest water quality rules. Both drinking water facilities were located in heavily populated areas; consequently, plant modifications had to be accomplished within their existing infrastructure footprints.

  6. Largest Ozone Facility In North America Meets Regulatory Requirements And Remediates Taste & Odor Problems
    4/27/2017

    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).

  7. Expansion And Upgrade Of WWTP Ozone Disinfection System Reduces Energy Cost By 69%
    4/27/2017

    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. Maximum Ozone Transfer Efficiency Across Broad Range Of Water Flow
    4/25/2017

    The design team for the intermediate ozone system at Buckingham Water Treatment Plant, Quebec, had limited space available for ozone contacting for the plant’s 1.3 – 7.4 MGD flow, so a standard fine bubble diffusion basin for ozone disinfection was not an option.

  9. Improving The Quality Of Tertiary Effluent For Indirect Potable Reuse With Geographic Constraints
    4/24/2017

    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. City Validates Innovative Reuse Treatment Options Without RO
    3/13/2017

    Hollywood, Florida’s 55.5 MGD Southern Regional Wastewater Treatment Plant (SRWWTP) treats wastewater from Hollywood and six neighboring municipalities in the southern region of Broward County. Florida’s outfall rule requires the city to begin a process to largely eliminate the use of its ocean outfall and implement 20.4 MGD of additional reuse on an annual basis.
