Water Membranes White Papers and Case Studies

  1. 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).

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. Oxygen Removal From Feedwater Of A Central District Heating System Using 3M Liqui-Cel
    2/18/2017

    A Netherlands power station installed 3M Liqui-Cel membrane contractors for O2 removal. This case study explains how the membrane system exceeded expectations, achieving oxygen removal down to 5 ppb.

  7. Dual Membrane Plant System Audit
    2/6/2017

    How do you know if you are in control of microorganisms in your dual membrane plant? See how one water treatment plant performed a system audit using ATP technology to confirm microbiological treatment efficacy through each stage of the process.

  8. Global Pharmaceutical Company EnviQ Membrane Bioreactor (MBR)
    11/4/2016

    The Serum Institute is a global pharmaceutical company that is one of the world’s largest producers of vaccines. The Institute was planning an expansion to their manufacturing plant in Pune, India, that resulted in an additional water requirement for the plant’s needs.

  9. From Raw Lake Water To Excellent Filtrate Quality Suitable For Drinking Water
    7/12/2016

    CH2M contacted Toray Membrane USA with an invitation to pilot our pressurized TIPS hollow fiber UF membrane module for the City of Sherman Texas 10 MGD Expansion Project. This document summarizes the findings of this pilot study program.

  10. Fractional Electrodeionization (FEDI) Technology For RO Permeate Polishing And Demineralization
    5/5/2016

    Sabine Pass, a large LNG refinery in the U.S., required a membrane desalination solution to cater to its extensive process water needs in order to produce a large amount of liquefied natural gas for export.
