Wastewater Contaminant Removal White Papers & Case Studies

  1. Design-Build Using Actiflo Technology
    3/6/2015

    A state-of-the-art 695-MW power generation facility was recently installed in the Northeastern U.S. to serve the country’s highest demand market. Its innovative power generation technologies, emissions control systems and process efficiencies make it one of the cleanest, most efficient and technologically advanced supercritical pulverized coal (SPC) power plants in the U.S.

  2. Coal Yard Runoff Compliance Using Actiflo® Technology
    3/6/2015

    Storm water runoff from a 37-acre coal storage yard utilized as part of daily operations at an industrial site in Southwestern Pennsylvania posed a problem when the Pennsylvania Department of Environmental Protection (DEP) updated the facility’s NPDES permit.

  3. Six-Effect Black Liquor Evaporation System
    3/4/2015

    The pulp mill at Veracel Celulose was commissioned in mid-2005. The HPD® black liquor evaporation system, designed by Veolia Water Technologies and installed by Confab Equipamentos S.A., was considered successful at start up.

  4. Black Liquor Evaporation And Chloride Removal System
    3/4/2015

    The Smurfit-Stone Hopewell mill needed to replace the existing three evaporator trains that were currently in place at this facility with one very highly integrated system.

  5. Design-Build Zero Liquid Discharge (ZLD) System — New Harquahala Generating Project
    3/3/2015

    The New Harquahala Generating Project serves as a power and electrical wholesaler in the Southwestern United States. To fill the need for growing energy consumption in the region, this facility was built to provide power to the area.

  6. Dissolved Air Flotation System Reduces Costs, Improves Process
    3/1/2015

    With the town of Johnstown, CO's, water treatment plant began operating its circular clarifier systems at maximum capacity to meet summer peak demand rates, consultants recommeded increasing plant capacity and using dissolved air flotation technology for their clarification process.

  7. Maximum Water Reuse, Zero Liquid Discharge — A Power Plant Case Study
    3/1/2015

    ELCOGAS, established in 1992 with the aim of building and operating a 335 MW Integrated Gasification Combined Cycle (IGCC) power plant as well as the commercialization of its technology.

  8. A Fairy Tale Ending At A Pump Station
    3/1/2015

    The Otay River Pump Station (ORPS) was upgraded in 2003, to feed effluent to the City of San Diego’s newly constructed South Bay Water Reclamation Plant. 

  9. Solving Foaming Problems At Your WWTP
    3/1/2015

    This project provides an unusual "before-and-after" comparison of how a high-solids loaded digester system with a Rotamix mixing system performed before and after the Foambuster was installed.

  10. Improving Influent Screen Washing For A Fraction Of The Estimated Cost
    3/1/2015

    The use of Vaughan's self-priming chopper pump and nozzles upstream of the influent screens is increasing the amount of fecal matter passing through the influent screens, which in turn improves plant efficiency and greatly increases the amount of cogenerated electricity from digester gas.
