Wastewater Treatment Case Studies and White Papers

  1. AquaSBR® System Achieves 96% BOD Removal At Rutter's Dairy

    Rutter's Dairy, located in York, Pennsylvania is operated as a pretreatment system prior to discharge to the municipal sewers. Before the installation of an AquaSBR system, Rutter's Dairy was discharging its wastewater directly to the municipality. Like many other food processors throughout the United States, Rutter's Dairy was assessed high municipal surcharges when wastewater BOD5 and TSS exceeded 300 mg/l

  2. Ultrafiltration Stormwater Recovery System At Cincinnati Zoo Reaches Optimal Performance

    The Cincinnati Zoo uses an ultrafiltration system (UF) to treat stormwater. The reclaimed water is collected from 14 acres of the park, including parking lots, animal exhibit yards, rooftop drains, and walking path storm drains

  3. MABR Is The Big Cheese For This Dairy Farming WWTP

    Hayogev is a residential development in the rural area of Jezreel Valley, with 1000 homes, agricultural fields and dairy farms. Located in an open field next to small farms, the local treatment facility handles wastewater from HaYogev and Midrach Oz. The customer was looking for a localized wastewater treatment solution to replace the existing pond system, which faced difficulties in treating the wastewater due to high levels of nutrients. A new state-level regulation concerning reclaimed water required the wastewater treatment plant (WWTP) operator to reduce the nutrients in the effluent stream. The solution had to be odorless and quiet, have low power consumption, and use the existing pond and structure.

  4. Turbo Blower Replaces Surface Aerator In Industrial Waste Water Treatment Plant Biologically And Energetically More Efficient

    The biologically biodegradable waste water from the Leverkusen Chempark and the households of the lower drainage basin for the Wupperverband (Wupper association) is cleaned by Currenta in a community waste water treatment plant.

  5. Vortex Wastewater Pumps
    Vortex pumps are primary sewerage pumps used to transport are sewerage through the wastewater treatment plant process. Because these pumps are required to handle the raw sewerage including grit and associated storm water runoff debris the abrasion rate is quite high. In this plant the pumps were lasting less than 1 year before severe abrasion caused reduction in tolerances leading to re-circulation. As the sewerage was no longer being efficiently transported to treatment the plants capacity was effectively reduced. Plant was considering replacement after 1 year a t a cost of $8,500.00.
  6. The Fine Points Of Headworks Screening (Part 2 Of 3)

    Protecting wastewater treatment facilities requires operators to think strategically about their unique challenges and identify the best solution for their specific requirements. Specifying the appropriate headworks system for the plant’s needs is arguably one of the most important design decisions a public works engineer will make.

  7. Chloramination Monitoring And Control

    Since the EPA has established that, together with free chlorine, monochloramine is a primary disinfectant, it has been possible to implement the process more intensively. Water that is treated with monochloramine has, depending on the source of the water, fewer problems concerning taste and odor than water treated with free chlorine. In addition, the chemically more stable monochloramine remains longer in the water, thus allowing a long-term disinfecting effect.

  8. New Developments In Thermal Dispersion Mass Flow Meters

    This paper describes a newly developed microprocessor-based thermal dispersion mass flow meter that uses four temperature sensing elements in its flow sensor instead of the traditional two elements and automatically manages changes in gas selection, gas temperature, gas pressure, and outside temperature.

  9. Ultrapure Boiler Water Production From Municipal Wastewater

    The term wastewater can be applied to a wide range of water sources from municipal sewage to storm runoff to industrial discharge water. By Michael Sheedy, Vice President of Technology and George Di Falco, Marketing Communications, Eco-Tec Inc.

  10. Turbo Blower Technology Saves Money And Energy For City Of Adelanto WWTP

    The City of Adelanto, Calif., wastewater treatment plant (WWTP) receives an average flow of 2.2 million gallons per day (MGD), but had a permit that allowed treatment of only 1.5 MGD.
