Drinking Water Filtration Case Studies and White Papers

  1. Mountain Regional Water District Deploys Next Generation On-Site Hypochlorite And Tank Mixing Technology To Meet Expanding Water Management Needs
    7/16/2018

    The Mountain Regional Water District is a Special Service District of the county that was established by the Summit County Commission in 2000 to regionalize water service by consolidating several public and private water companies.

  2. Water Wholesaler In Dallas Fort-Worth Metro Area Upgrades To New Generation Of On-Site Hypochlorite Generation To Improve Safety And Reliability
    7/12/2018

    The Upper Trinity Regional Water District (UTRWD) is a conservation district created by the State of Texas in 1989 to provide water, wastewater, solid waste and storm water services to numerous towns and cities approximately 50 miles northwest of Dallas. In 2010, the UTRWD installed three 2,000 pound per day (PPD) chlorine equivalent Microclor® OSHG systems. The systems continue to provide UTRWD with a reliable supply of hypochlorite for disinfection in a manner that is less expensive and less risky than gas chlorine or liquid bulk hypochlorite delivered via truck or rail through such a heavily populated area.

  3. San Jose Water Company Solves Chloramine Residual Problem With The Process Solutions, Inc. Monoclor™ 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.

  4. Biological Ammonia Removal From California Groundwater Source
    6/12/2018

    A novel biological oxidation filtration treatment process was evaluated for removal of ammonia from a California groundwater source. In addition to ammonia, this groundwater had other contaminants such as iron, manganese, methane, hydrogen sulfide odor, color, high organic carbon, etc. As such, more conventional treatment processes such as breakpoint chlorination were deemed infeasible, and biological treatment was the preferred treatment alternative.

  5. Evaluation Of Filtration Media For High Rate Surface Water Filtration
    6/12/2018

    The existing water filtration facility in Clinton MA is a high rate, direct filtration process that has been on-line since 2006. The water filtration plant draws it raw water from the Wachusett Reservoir. Chemical feed systems are provided for chemically assisted filtration, pre-oxidation (potassium permanganate), coagulation, pH and alkalinity adjustment (sodium bicarbonate and sodium hydroxide), and disinfection (sodium hypochlorite).

  6. Bringing An END™ To RO Brine And Difficult Brackish Water Treatment
    6/8/2018

    Access to clean, safe, fresh water is one of the greatest challenges facing humanity in the 21st century. By some estimates over 1.5 billion people face water scarcity issues that directly threaten their health or economic welfare on a daily basis. More concerning, the impacts of climate change and global population growth are expected to exacerbate these issues to impact over 2.3 billion people by the year 2050. These sobering facts are why six of the United Nations (UN) Sustainable Development Goals (SDGs) are focused on providing access to clean, safe water. Part of solving this challenge is reducing industrial water consumption to conserve water resources.

  7. Evaluation Of Ceraflow-50 As A Filtration Media For Hexavalent Chromium Treatment
    6/1/2018

    Pilot testing was conducted to evaluate the relative performance of 4 filter media, including Ceraflow-50, as part of a reduction coagulation filtration (RCF) treatment process for the removal of hexavalent chromium (Cr(VI)) from groundwater. This evaluation was conducted at multiple well sites for a water utility in California.

  8. Put An END™ To Silica Fouling
    5/25/2018

    Despite the tremendous advancements in water treatment technology over the past several decades, a handful of compounds remain significant challenges.  Among the most challenging for water treatment systems is silica which can lead to irreversible fouling in modern (RO) treatment systems.  Magna Imperio’s new Electrochemical Nano Diffusion (END™) process offers a simple and cost-effective solution for treatment of raw water and brine streams with high silica concentrations.

  9. Evaluation Of Ceralite-A As An Alternative To Anthracite Filter Media
    5/25/2018

    The Golden Heart WTP located in Fairbanks Alaska is a lime softened, ground water treatment plant with five filter basins, with a combined surface area of 1495 ft2 . Typical filter loading rates are in the 2.3 –to 3.1 gpm/ft2

  10. Santa Barbara, Curaçao Desalination Plant: Six Years Of Operation Of LG Chem Thin Film Nanocomposite (TFN) SWRO Membrane
    5/14/2018

    The Santa Barbara desalination plant located in the south-eastern part of Curaçao provides drinking water to about half of the population of this Caribbean island. With an average precipitation of approximately 500 mm, rainwater is the only natural source of freshwater in the island. Government efforts to address the water shortage problem date back to the 20s of the last century. Initially based on evaporation, the seawater desalination evolved into the reverse osmosis technology in the 90s. After several years of experimenting with RO, Aqualectra, the municipal supplier of potable water and electricity for Curaçao, took the decision to move forward with this technology and in 2003 started a project to build a SWRO desalination plant.
