Drinking Water Filtration Case Studies and White Papers

  1. 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. 

  2. 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.

  3. Town Of Kittery, Maine Relies On Lime Feeders For pH Control For More Than 25 years
    6/26/2017

    The Francis L. Hatch water filtration plant is in the coastal town in York county Maine and has an average capacity of 2.6 MGD. This is a surface water plant that utilizes hydrated or “slaked” lime (calcium hydroxide) to maintain the pH level around 7.0. For over 25 years, the district has used two of the UGSI Chemical Feed model 32‐055 Feeders to mix dry hydrated lime with water to create a lime slurry solution that can then be added to the finished water treatment.

  4. 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.

  5. Manufacturing Plants Based On The Lego Principle
    5/2/2017

    Small batches and multiple products in the same plant — these are the market demands to which more and more manufacturers need to adjust. The answer is based on the "Lego principle."

  6. 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.

  7. 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.

  8. 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.

  9. 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).

  10. 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.
