Wastewater Treatment Case Studies and White Papers

  1. Brewery Reuses Water For Factory Wash-Down
    11/11/2013

    Looking to reduce its water footprint, Shepherd Neame Brewery invested in a complete membrane bioreactor (MBR) wastewater recovery and re-use plant. Learn how the new plant's aeration system has helped to reduce the brewery's water-to-beer ratio to an industry-leading value of 3:1.

  2. Chlorine vs. Chloramine: A Tale Of Two Chemistries
    4/17/2018

    In drinking water treatment’s ongoing battle between disinfection and disinfection byproducts (DBPs), most water utility customers are oblivious to the process. One thing they do notice, however, is when their water smells or tastes bad. Here are some insights that can help water treatment plant (WTP) operators deal with their internal concerns about DBPs and residual chlorine or ammonia levels, as well as their external concerns about customer perceptions of water quality.

  3. Flat-Sheet Membrane Units Increase WWTP Capacity
    12/18/2013

    Following several years of inadequate performance and intensive cleaning requirements, the owners of the Callao, VA, wastewater treatment plant looked for a solution. The installation of two flexible, flat-sheet membrane units provided an instant capacity increase and a decrease in sludge accumulation, resulting in streamlined plant operations.

  4. Monitor Your Pump For Process Efficiency
    12/3/2017

    Pumps are all too frequently one of the most overlooked and abused pieces of equipment in process automation, yet nothing moves without them and a process becomes inefficient when they don’t operate properly or completely shutdown. 

  5. Los Alamos WWTP Gains Turndown Capability And Saves Energy With Hybrid Blowers
    7/14/2015

    Los Alamos, NM, the former site of topsecret laboratories where government scientists developed the atomic bomb during World War II, is once again a town at the forefront of new technology.

  6. White Paper: Studies Of A Microbial Mixture With Useful Properties For The Treatment Of Organic Sewage
    8/17/2010

    The importance of bacteria in the treatment of raw sewage and water purification is well known. Here, we report on Sewper Rx, a unique mix of bacteria with powerful properties for treating sewage as well as other water cleaning applications. By Brian T. Butcher, PhD and Lisa Morici, PhD

  7. New Developments In Thermal Dispersion Mass Flow Meters
    9/15/2014

    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. By John G. Olin, Ph.D., Founder/Chairman, Sierra Instruments

  8. Treatment Plant Modernized To Meet EPA Turbidity Regulations
    6/25/2014

    GF Piping Systems technology and its unique approach to business are an integral part of Akron’s plant improvement plans.

  9. The Challenges Of Combined Heat And Power Generation From Biogas
    3/16/2018

    Driven by tight budgets and competing needs for limited CAPEX funds, wastewater treatment plants are increasingly looking to reduce their operating expenses. Many are now referring to themselves as water resource recovery facilities (WRRFs), reflecting a heightened focus on recovering nutrients, methane, and a host of other properties from their waste flows. The largest boon to date has come from thermal energy, but producing biogas comes with its own set of challenges, including accurate gas flow measurement.

  10. 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
