Wastewater Treatment Case Studies and White Papers

  1. Successful Ammonia Removal From Wastewater Using 3M™ Liqui-Cel™ Membrane Contactors At A European Manufacturing Facility
    8/10/2017

    Ammonia is used as a cleaning and bleaching agent in the production of fertilizers, plastics, explosives, and many other products.

  2. Headworks Bio Commissions First IFAS System In Costa Rica
    1/2/2015

    In late 2013, Headworks Bio Inc. was awarded a contract with General Contractor Soluciones Tecnicas Ambientales, S.A. (SOLAMSA) to supply an IFAS system to upgrade the existing Ptar El Roble conventional activated sludge (CAS) treatment facility in Puntarenas, Costa Rica — the first IFAS installation in the country.

  3. New And Innovative Rare Earth Technology For Low-Level Phosphorus Removal
    9/18/2014

    With environmental regulations continuing to restrict the discharge of phosphorus from wastewater treatment facilities, traditional methods of phosphorus removal are proving inadequate.

  4. What You Didn't Expect: Aerators Offer More Benefits Than Just Clean Water And Aesthetics
    11/9/2010
    A natural, environmentally safe and cost-efficient way to ensure that your pond maintains a healthy, aerobic state is through the use of aeration systems. By Robin Bio, Marketing Coordinator
  5. Treatment Of Produced Water By Electrocoagulation
    2/10/2016

    Produced water (PW) is salty water trapped in the reservoir rock and brought up along with oil or gas during production. It subsists under high pressures and temperatures, and usually contains hydrocarbons and metals. Therefore, it must be treated before being discharged to surface water. Different techniques are being used to treat PW through phase separations, system control and design, and chemical treatments. In this paper, we discuss our experimental results on treating PW through electrocoagulation (EC).

  6. Pilot Studies In North Carolina With Hydrex™ Odor Solutions
    10/17/2014

    Two municipalities were faced with odor issues and required corrosion prevention in their collection systems. Monitoring in the sewer lines indicated peak H2S atmospheric concentrations of 300-500 ppm. Both clients desired H2S < 20 mg/L to prevent corrosion and preferably lower to prevent H2S odor.

  7. Z-92®/Z-33™ Uranium-Arsenic Treatment Process - Schurz Elementary School, Nevada Case Study
    8/9/2012

    This uranium, arsenic and gross alpha removal pilot study was conducted for the Schurz Elementary School treatment facility in Schurz, Nevada. The Schurz Elementary School well contains concentrations of uranium, arsenic and gross alpha in excess of the State regulated Maximum Contaminant Levels (MCL).

  8. Feature Installation: City Of LaGrange Wastewater Treatment Facility, KY
    11/9/2010
    LaGrange Utilities Commission operates a 775,000 gallon (2934m3) per day wastewater treatment facility located northeast of Louisville, near the I-71 and KY 53 interchange.
  9. The Role Of pH Measurement During Coagulation
    9/20/2018

    In the wastewater treatment industry, coagulation has become one of the most widespread processes for effectively separating contaminants and effluent. But coagulation is a complicated and sensitive process, one that alters the chemical balance of the wastewater in order to strip it of unwanted constituents. As in many such processes, pH plays a critical role, and treatment professionals must analyze it closely if they want to properly coagulate their product.

  10. Fine Bubble Aeration System Reduces Power Consumption, Saves Money
    4/23/2012

    With significant increases in production, the static tube aeration system at F&A Dairy was unable to deliver sufficient oxygen to the lagoon treatment system. By Environmental Dynamics International
