Wastewater Treatment Case Studies and White Papers

  1. The Often Overlooked Benefits And Versatility Of GRO And GR Systems For Existing Plants

    Schreiber has designed and installed several dual GR plants in which one unit serves as the aeration/clarification unit and other unit serves as the digester/thickener/clarification unit. At the Mirasol, MO plant, the GR digester was sized to allow digestion/clarification in the initial phase, thus satisfying the clarifier duality required in many states, and will be converted to a digester/thickener in a future plant expansion.

  2. Special Gas Chlorination System Replaces Tablet System At WWTP, Providing Enhanced Safety Needed For Gas Option, While Cutting Chemical Costs

    The district manager for the Pinetop-Lakeside Sanitary District (AZ) reports that a special gas chlorination system, featuring unique components and controls, and manufacturer-supplied service, has effectively replaced a chlorine tablet system.

  3. Boat Hull Cleaning

    A major U.S. waste management company provided a sample of wastewater generated by an underwater ship cleaning operation. The sample was to be tested in the KASELCO laboratory for removal of copper and zinc and for improvement of clarity (suspended solids removal). Customer is interested in treating 50GPM.

  4. New Septage Receiving Plant Results In Decreased Maintenance

    Previously to installing their new Septage Receiving Station 18-Mile Creek WWTP had very little protection from unknown debris entering their plant from haulers. The plant reports that in the time that the RoFAS Septage Drum and WAP Washpress have been operating, they’ve processed many septage loads without issue.

  5. Electroplating 1 (CrVI, Ni, Zn, Cu)

    XXXX Plating Company operates a decorative plating shop in Los Angeles, Ca., doing finishes in nickel, copper, and chromium.

  6. CleanFlo™ Monoscreen® Case Study

    When the polar bears at the Brookfield Zoo were introduced to their new habitats at the Great Bear Wilderness, they had no idea how much more fulfilling their life would become.

  7. Mine Process Waste - Several Metals

    An international mining company was looking at electrocoagulation for waste treatment at a copper mine in South America. A sample from ore processing was provided for bench-scale testing.

  8. Seven Tips To Cut Wastewater Aeration Energy Costs With Thermal Mass Flow Meters

    One of the biggest expenses in wastewater treatment operations is the cost of energy to run the blowers and compressors that produce air for the aeration basins.

  9. Application Note: The Ultrameter II™ In Municipal Wastewater Treatment

    Publicly Owned Treatment Works (POTWs) are faced with the challenge of processing the effluent wastes of multiple sources: residential, industrial, and environmental. Under laws governing pretreatment, the ultimate responsibility in determining whether or not industrial effluent meets criteria for treatment belongs to the POTW. Once the POTW has the effluent waste within the confines of its treatment facility, it is accountable to the federal, state, and local regulations governing the quality of the wastewater it discharges into lakes and streams or injects underground.

  10. Clogging Problem Solved; Maintenance Cost Reduced; 15 Percent Less Power Consumption Delivered

    A WWTP facility in Indiana serves a six-square-mile area, and has historically experienced pronounced peak flows caused by nearly one-fourth of its  collection system consisting of combined storm water and sanitary sewer lines.
