Contaminant Removal Case Studies and White Papers

  1. Bulk Hypochlorite Disinfection System Replaced With On-Site Hypochlorite Generation System Saving About $160,000 Per Year In Materials

    Originally built to treat 10 million gallons per day (MGD), the Quail Creek Water Treatment Plant in Washington County, Utah, now has an operational capacity of 60 MGD and a design capacity of 80 MGD.

  2. Utility Removes Burdensome Bulk Sodium Hypochlorite From Operations

    Historically, Lyon County Utilities, Nevada, applied 12.5% bulk sodium hypochlorite for disinfection at each of their well sites. Always looking to improve system efficiency, Lyon County staff reexamined on‐site hypochlorite generation to determine if the use of the 0.8% sodium hypochlorite solution could mitigate the challenges associated with dosing high strength sodium hypochlorite.

  3. Tank Shark® Active Tank Mixing Proven To Be Superior To Dedicated Tank Inlet/Outlet Design

    San Jose Water Company (SJWC) provides drinking water for over a million people in the greater San Jose Metropolitan region and is a recognized leader in drinking water treatment and distribution system water quality management. With over 90 water storage facilities in service, planned maintenance and rehabilitation of capital assets is a key component of SJWC’s CIP program.

  4. Unsafe Levels Of Toxic Chemicals Found In Drinking Water Of 33 States

    Levels of a widely used class of industrial chemicals linked with cancer and other health problems — polyfluoroalkyl and perfluoroalkyl substances (PFASs) — exceed federally recommended safety levels in public drinking-water supplies for 6 million people in the United States, according to a new study led by researchers from the Harvard T.H. Chan School of Public Health and the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS).

  5. Expansion And Upgrade Of WWTP Ozone Disinfection System Reduces Energy Cost By 69%

    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.

  6. Southern California Water District Reduces Polymer Usage 30% With PolyBlend® Polymer Activation System

    Santa Margarita Water District (SMWD), located in southern California’s Orange County, between Los Angeles and San Diego, provides drinking water and wastewater services to over 165,000 residents and businesses. SMWD approached UGSI Solutions about a PolyBlend® Polymer Activation System trial at their 3 A Water Reclamation Plant.

  7. Update And Upgrade Of Ozone Dissolution System At Southwest Water Treatment Plant

    The burden of the unavailability of replacement parts for the aging generators and the FBD basins' high maintenance motivated the Orlando Utilities Commission's Southwest Water Treatment Plant to update and upgrade the plant’s ozone system.

  8. Evaluation And Optimization Of Clean-In-Place Using Ozone

    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.

  9. Indirect Potable Reuse With UV-Oxidation - Big Spring, Texas (Case Study)

    In an effort to reduce reliance on dwindling surface and groundwater supplies in Texas, the Colorado River Municipal Water District (CRMWD) constructed a new Raw Water Production Facility (RWPF) in Big Spring. Big Spring is a 27,000-member community located in West Texas approximately 300 miles west of Dallas. This RWPF treats secondary wastewater to a standard that allows it to be re-introduced directly into the raw water supply for the water treatment plants of Big Spring, Odessa, and other communities in the region.

  10. Hendersonville Water Treatment Plant Features Innovative Disinfection System

    Hendersonville Utility District (HUD) serves one of the most populous suburbs of Nashville, Tennessee.
