Drinking Water Filtration Resources

  1. Treatment Plant Upgrade Eases Operations And Increases Safety 7/24/2018

    Now in operation for well over two years in the Malambo, Colombia, the Microclor® system has proven itself in terms of reliability and safety. According to management, the clear, vertically-oriented cells and the system’s open architecture allow for easy inspection and simplify any minor maintenance that might be required.

  2. Burnsville Becomes First Metro System With On-Site Hypochlorite Generation 7/24/2018

    When Linda Mullen took over as water superintendent in Burnsville in 2007, the city was in the process of adding surface‐water treatment to its existing plant. Burnsville began purchasing water from the nearby Kraemer Mining and Materials quarry, both to supplement its supply and to help the quarry meet discharge permits.

  3. Utility Enjoys More Than Seven Years of On‐Site Sodium Hypochlorite Production 7/16/2018

    “To me, Microclor® is the top of the line on‐site generation system on the market due to low maintenance and it being very user friendly.” Larry English, Water Quality Manager, Daphne Utilities. Read the full project profile to learn more.

  4. 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.

  5. 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.

  6. 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.

  7. 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

  8. 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.

  9. Addressing Fouling Challenges In Water Treatment With RO Membrane 4/18/2018

    Reverse osmosis (RO) membranes are widely used in potable water, wastewater, and industrial applications. However, a major issue in the application of RO membrane technology for desalination and wastewater reclamation is membrane fouling. It limits operating flux, decreases water production, and increases power consumption. Membrane fouling also increases the need for RO plants to perform periodical membrane CIP procedure. These problems decrease process efficiency, increase operation cost, and raise environmental issues related to the CIP solutions disposal.

  10. Exploring RO's Inner Net 3/14/2018

    A deep dive into reverse osmosis (RO) elements reveals the importance of feed channel spacers for optimal membrane filtration system performance.
