Drinking Water Disinfection [Case Studies White Paper]

  1. Conversion To On-Site Sodium Hypochlorite Generation Improves The Safety And Resilience Of Two Wastewater Reuse Plants With A Three-Year Economic Payback
    7/10/2018

    Aqua Engineers is a local Hawaiian company founded almost 40 years ago which delivers operations, engineering, and construction management to the water and wastewater industry throughout Hawaii. Also, as an owner and operator, Aqua Engineers is keenly focused on the return on investment for process equipment decisions, but also on the safety of its operators and surrounding community. Read the full case study to learn why Aqua Engineers chose the Microclor OSHG system provided by UGSI Solutions for both their sites in 2016.

  2. Monitoring Chlorine Residuals For RO Membranes - ORP Versus Chlorine Analyzers
    7/14/2015

    In processes where disinfection is required chlorine is the most common and economic disinfectant followed by sodium hypochlorite (liquid bleach). It is important to disinfect the RO feedwater to avoid fouling of the membranes which results in poor performance and frequent cleaning.

  3. OSG- On-Site Sodium Hypochlorite (NaOCl) For Drinking Water Applications
    5/31/2011

    Drinking water treatment plants use various forms of chlorine to inactivate pathogens, oxidize metals or metalloids and provide disinfection residual for distribution systems. By Glen Smith, PEPCON Systems

  4. Degas Separator Selected For Wichita Aquifer Storage And Recovery Project
    4/26/2017

    In the 1990s, the City of Wichita, KS, developed a water supply plan that included creating a sustainable water supply through the year 2050. The key component of the plan is recharging the large aquifer that lies under the region with 100 MGD of water from the Little Arkansas River.

  5. A Pilot Study Involving Three Different Treatment Media
    10/8/2018

    As part of a feasibility study for arsenic treatment at an elementary school in California, a pilot study was conducted to test the performance of three different treatment media: (1) greensand and anthracite, (2) standard sand and anthracite, and (3) manganese dioxide.

  6. Indiana American Water Eliminates Gaseous Chlorine At Hidden Lake WTP In Warsaw, Indiana
    7/20/2018

    In 2000, Indiana American Water, a subsidiary of American Water Company, purchased the Warsaw Indiana system which serves a population of over 16,000. Indiana American then completed a Comprehensive Planning Study that included a number of upgrades and improvements to enhance the reliability, safety and water quality of the system.

  7. MEMCOR® Continuous Microfiltration System Maximizes Water Resources For The City Of Scottsdale, Arizona
    3/26/2013

    The desert community of Scottsdale, Arizona had no natural surface water sources and a decreasing groundwater supply. Scottsdale had historically treated and disposed of its wastewater.

  8. Encore® 700 Chemical Metering Pumps Provide SNWA With A Decade Of Flawless Service At River Mountains
    8/15/2016

    Built in 2002, Southern Nevada Water Authority’s (SNWA) River Mountains Water Treatment Facility is a state-of-the art  water treatment facility that delivers 300 million gallons per day and was designed to be expanded to deliver up to 600 million gallons per day of treated water in the future.

  9. San Jose Water Company Solves Chloramine Residual Problem With The Process Solutions, Inc. Monoclor® RCS Chloramine Management System
    7/10/2018

    A San Jose Water Quality Engineer said, "I wasn’t convinced that PSI’s Monoclor chloramine dosing system would solve our problems after several failed attempts to improve residual, but with PSI offering a trial including installation, operation, and troubleshooting for three months, San Jose Water decided to invest the necessary resources to pilot this system.

  10. Pilot Test For Manganese Removal Using Manganese Greensand
    10/11/2018

    Loprest has been designing and fabricating manganese removal systems using manganese greensand for over forty years. Drawing on that experience; filtration rates, run times, backwash procedures, chemical dosage rates, etc. are all established by theoretical calculations and history. Therefore, Loprest’s goal in this pilot study was to conduct uninterrupted operation per bid testing procedures and document the results.
