Drinking Water Filtration Case Studies and White Papers

  1. Iron, and Manganese Arsenic Pilot Study In The Golden State
    10/1/2018

    This report summarizes results and conclusions of a groundwater treatment pilot test program. This pilot test program was undertaken to demonstrate the effectiveness of water treatment products that employ oxidation and filtration to remove iron, manganese and arsenic to levels well below MCL’s. Operating data collected during the study will be used to confirm the design of fullscale facilities.

  2. Groundwater Treatment Pilot Test Program Proves Successful In California
    9/12/2018

    Iron, manganese, arsenic and hydrogen sulfide are indigenous to numerous groundwater aquifers. With the exception of arsenic, these constituents are more prevalent in deeper aquifers that are devoid of dissolved oxygen. This report summarizes the results and conclusions of a groundwater treatment pilot test program. This pilot test program was undertaken to determine the removal performance for arsenic, manganese and iron at the City of Merced’s Well 20 site. Chemical treatment processes required were also studied.

  3. 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.

  4. Harmful Algae: How To Stay Ahead Of The Bloom
    9/6/2018

    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.

  5. 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).

  6. 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.

  7. Basin Nozzle Manifold Contacting System Installation Remediates Taste And Odor Compounds, Meets Disinfection Goals
    9/1/2018

    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.

  8. 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.

  9. Maximum Ozone Transfer Efficiency Across Broad Range Of Water Flow
    8/25/2018

    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.

  10. Evaluation And Optimization Of Clean-In-Place Using Ozone
    8/15/2018

    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.
