WASTEWATER FILTRATION RESOURCES

  • Filtering Out Failures: A Productive Conversion Experience For A Steel Mill

    Water filtration in steel manufacturing should be one of those things that mill owners never have to worry about. But when filter systems fail to perform as expected, it’s time to invest in a smarter design. That was the situation at a midwestern steel mill that embarked on a major, eight-year conversion of its water filtration infrastructure.

  • Anammox Sidestream Deammonification Process Allows Plant To Reduce Capital And Infrastructure Costs

    Pierce County’s main goal was to reduce the discharge of nitrogen to Puget Sound while also reducing plant operating costs while in nitrogen removal mode. After upgrading, the new system continues to remove greater than 80 percent of ammonia and 75 percent of total inorganic nitrogen, equating to a reduction of over 400 tons per year of nitrogen loading to Puget Sound.

  • MBBR Technology Helps Plant Maintain Discharge Compliance, Achieve Sustainable Growth

    A bacon processing plant in the Midwest was overloaded by more than 50%. Even though the system continued to maintain compliance, the plant proactively decided to expand its wastewater treatment facility to ensure they met their growing demand and maintained their standing as exemplary corporate citizens and environmental stewards.

  • Mobile Home Park Installs Modular MBR System To Save Valuable Space

    Bay Meadows is a year-round RV and mobile home park located along the shores of Lake Ontario. The facility had been reliant on subsurface treatment, however current regulatory requirements eliminated the option of continuing with that approach. In addition to high bedrock, the lack of available area due to design flow values meant a more sophisticated sewage treatment solution would be necessary.

  • Grundfos Solutions For Industrial Water Reuse

    Water is such a fundamental necessity for life that it is often taken for granted. In modern industrial societies, the water from every tap is expected to be so pure that we can drink it without a second thought. However, the reality is much more complicated. Mankind is becoming increasingly aware that fresh water is a rarity, and the process of water treatment is vitally importance to us all. This white paper is intended to introduce the reader to the many elements that constitute the water reuse process.

  • Low-Fouling RO Tech Keeps Replacement Costs Down At Wastewater Reuse Plants

    By using Toray's low-fouling polyamide composite membranes, the WTPs at the AMATA estates operated the RO systems for more than five years before requiring replacement of the RO elements. This low rate of replacement has considerably helped the end-user save operational and capital costs and is noted as one of the most successful wastewater reuse plants in Thailand.

  • Devastated Community Finds Innovative Wastewater Solution

    The community of Kinglake West was on a waiting list to receive government financing for a new sewer system when, in 2009, a disastrous fire swept through the area. The damage was so extensive that funding for a wastewater collection system was expedited. The new system needed to be up and running as soon as possible, without being an undue financial burden to homeowners.

  • AquaDiamond Cloth Media Filters Achieve 0.1 mg/L Total Phosphorus Limit

    With the current national emphasis on restoring the water quality of America’s urban waterways, the City of Brockton, Massachusetts, Advanced Water Reclamation Facility (AWRF) wanted to stay ahead of the regulatory cycle – in particular, phosphorus discharge limits set forth by the National Pollution Discharge Elimination System (NPDES) program of the United States Environmental Protection Agency (U.S. EPA). For this region of the country, the U.S. EPA has proposed total phosphorus (TP) discharge limits of 0.1 mg/L.

  • AquaDisk® Filters Reduce TSS And NTU For Power Plant Process Water

    Shepard Energy Centre (owned by Enmax and Capital Power Corporation) is located in Calgary, Alberta, Canada. It began operating in March 2015 and is capable of generating over 800 megawatts of electricity to Alberta residents using natural gas. The facility utilizes (2) combustion turbines featuring a combinedcycle technology to generate electricity, and in addition, processes waste heat through a steam turbine to produce even more electricity. This electricity generation process makes Shepard approximately 30% more efficient than traditional coal-fired plants, and reduces overall fuel costs. Not only is Shepard’s plant more efficient, but better for the environment by emitting less than half of the CO2 emmissions per megawatt hour compared to a coal generated facility. Sulphur dioxide and nitrogen dioxide emissions are also reduced.

  • Automotive Plant Wash Water Removes Cutting Fluid/Oil And Suspended Solids From Water

    An automotive parts manufacturer producing millions of parts per year was seeking to remove cutting fluid/oil and suspended solids from water used in its parts-washing process to enable water recycling and reuse in the parts washer. Successful lab testing and trials enabled the system integrator to win the project and install full-scale systems utilizing PPG’s UF membrane element. Read the full case study to learn more.

  • PhotonMaster™ Luminometer

    Reliable data starts with a reliable device. Generate your data from the PhotonMaster, a luminometer that is sensitive enough for the cleanest sample, robust enough for the toughest testing environment, and cost-friendly for any budget.

  • inDENSE™

    World Water Works’ inDENSE system increases process throughput and performance through the selection of dense sludge aggregates with improved settling rates and the promotion of enhanced biological phosphorus removal (EBPR).

  • DEMON®

    DEMON® is the continuous or SBR deammonification process utilizing granular anaerobic ammonium oxidizing bacteria (anammox) biomass for aiding in reduction of high strength ammonia from side stream solids dewatering facilities reject flows. World Water Works’ DEMON process can solve the problem of returning high concentrations of ammonia to the plant influent. The true key to the success of the technology is the patented advanced biological process controls and the physical separation used to facilitate the growth and retention of the anammox bacteria.

  • Pressure Filters

    WesTech granular activated carbon (GAC) contactors are an effective means for removal of low-molecular-weight contaminants from aqueous solutions.
