Wastewater Case Studies and Whitepapers

  1. How To Handle Unexpected Contaminants In Water 8/30/2022

    Read why temporary water treatment system may encounter new or unexpected contaminants that did not initially show up in samples, and what businesses can do in response.

  2. Minimizing Aerated Wastewater Treatment System Servicing 12/27/2024

    Reliability is especially important in the wastewater treatment sector. One is that the blowers have to dependably operate in conditions that are often very harsh.

  3. Clogging Problem Solved; Maintenance Cost Reduced; 15 Percent Less Power Consumption Delivered 3/6/2015

    A WWTP facility in Indiana serves a six-square-mile area, and has historically experienced pronounced peak flows caused by nearly one-fourth of its  collection system consisting of combined storm water and sanitary sewer lines.

  4. The Benefits Of Adaptive Control Systems 2/21/2019

    In municipal and industrial wastewater treatment, there has been a shift from manual to automatic process control in order to increase efficiency and improve effluent quality.

  5. CAGI Data Sheets: Blower Performance Comparison Technical White Paper 2/13/2018

    Comparing blower performances across different manufacturers and technologies has long been a difficult task. For many years, it was all too easy to present data that, although accurate, was potentially misleading. Manufacturers were selective about what information they published as well as what conditions they chose to specify performance. The result was a numbers game the buyer frequently lost. Fortunately, the Compressed Air and Gas Institute (CAGI), in cooperation with its members, has developed a tool for a fair comparison between blowers.

  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. Rental Blowers Provide Timely Solutions For Temporary Aeration Concerns 10/2/2019

    With a continuous flow of air required to maintain dissolved oxygen (DO) levels, the last thing a wastewater treatment plant (WWTP) operator wants is to come up short of the volume needed to sustain good microbial growth. With today’s ready availability of high-efficiency rental blowers, losing blowers to unplanned downtime or being unable to test new aeration systems before commissioning are no longer the threats they once were.

  8. Article: Floating Horizontal Aerators Enhance Eufaula, Alabama Activated Sludge Plant 1/18/2008
    The Eufaula, Alabama, wastewater treatment plant (WWTP) is an extended aeration activated sludge facility designed for an average daily flow rate of 2.7 million gallons per day (mgd). Prior to February, 2005 this WWTP used vertical aerators to provide oxygen and mixing in its aerator basins. The plant has two aeration basins, each 1.87 million gallons in volume, which had 160 horsepower (hp) of vertical aerators in each basin
  9. WTP Chooses A-758 Plus™ Lime Slaker Systems To Replace Existing Systems 12/6/2016

    The Albert R. Davis Water Treatment Plant (WTP) in Austin, Texas, is one of three water treatment plants supplying drinking water to the greater Austin metropolitan area. The plant was built in 1954 and has had multiple upgrades over the years, increasing its capacity to 118 million gallons per day (MGD).

  10. BOD Interceptors: Transforming Wastewater Treatment Plants Into Renewable Energy Resources 2/12/2014

    In communities across the United States, wastewater treatment plants are consuming vast amounts of energy to remove and dispose of energy rich organics. As any government comptroller can attest, the cost of the energy required to run a conventional activated-sludge treatment plant takes up a large portion – up to 40% – of a municipality’s budget.  Ironically, the very substance being treated could produce more than enough energy to run the treatment plant itself.
