WASTEWATER TREATMENT CASE STUDIES AND WHITE PAPERS

  • KLa Slot Injector Aeration System For CFAS Process Touch Panel Manufacturing Plant Wastewater Treatment

    The plant manufactures touch panel and polarizer which are materials for LCD assemblies. Since the manufacturing process is a semiconductor process, the wastewater contains large quantities of organic solvent from developers, strippers and rinse liquid waste. By KLa Systems

  • Case Study: New Pumps Make Excess Water Removal More Efficient For Power Generation Facility The Progress Energy Lee Plant, a power generation facility located in Goldsboro, NC, originally enlisted nine vertical sump pumps to assist in yard drainage. The pumps removed excess water that accumulated from rainfall and storm drains, equipment wash down, and general water overflow, and redirected it to a retention settlement basin. They featured a vertical design, wherein the motor is located above the pump, and a line shafts extends down into the length of the sump. As the pumps aged, they became increasingly expensive to maintain. Plant management began to question the long-term feasibility of efficiently maintaining the pumps to meet the plant's operational expectations
  • Case Study: First Municipal-Industrial Water Reuse Project In Virginia! Hampton Roads Sanitation District was created in 1940 to reduce pollution in the Chesapeake Bay. It currently serves a population of approximately 1.6 million with nine regional wastewater treatment plants in Hampton Roads and four smaller plants on Virginia’s Middle Peninsula. HRSD set the goal to reuse its treated wastewater for nonpotable purposes in the 1980s. An oil refinery located next to their York River Treatment Plant approached HRSD in 1996 to supply reclaimed water for the refinery’s cooling and process water. Previously, the refinery utilized increasingly expensive potable water and upgrading its own treatment facilities was too large an investment. In December 2000, HRSD signed a 20-year agreement to provide the refinery with 0.5 MGD of reclaimed water

  • White Paper: Water Reuse Strategies: Steel Industry Case Studies

    The steel industry has historically presented challenges for effective water treatment because it is a high water user and the applications may involve high heat, critical noncontact cooling, direct contact cooling, high suspended solids waters, oil and grease contamination, and complicated cascading. By Dave Christophersen, Veolia Water Technologies

  • Indirect Potable Reuse With UV-Oxidation - Big Spring, Texas (Case Study)
    Indirect Potable Reuse With UV-Oxidation - Big Spring, Texas (Case Study)

    In an effort to reduce reliance on dwindling surface and groundwater supplies in Texas, the Colorado River Municipal Water District (CRMWD) constructed a new Raw Water Production Facility (RWPF) in Big Spring. Big Spring is a 27,000-member community located in West Texas approximately 300 miles west of Dallas.

    Trinity River Authority Increases Filtration Capacity And Decreases Backwash With AquaDiamond® Cloth Media Filters By Aqua-Aerobic Systems

    The Trinity River Authority (TRA) of Texas established its Central Regional Wastewater System (CRWS) in 1957 and began operations in December 1959.

  • Wastewater Energy Program Case Study: Scheid Vineyards
    Wastewater Energy Program Case Study: Scheid Vineyards

    Scheid Vineyards, located in Greenfield, California, captures wastewater influent from the winery in three aeration ponds to supply the needed biological oxygen demand (BOD) to treat the effluent prior to being used for irrigation. In 2009, the wastewater plant processed over 8 million gallons of wastewater. The existing aeration system was inefficient and maintenance intensive leading the facility to explore alternative solutions.

  • 31% Energy Savings For Skanderborg Waste Water Treatment Plant With New 55 kW Atlas Copco ZS Blower

    With a savings goal set at 25 % for the Danish waste water industry, optimizing all parts of the operation, so even the aeration, is of the highest importance. In 2011, The Skanderborg Waste Water Treatment Plant replaced one of its 75 kW lobe blowers with a new 55 kW Atlas Copco ZS screw blower and were able to reduce their energy consumption with 31%.
