Wastewater Case Studies and Whitepapers

  1. Understanding The PeriFilter Technology

    There is a newly-developed technology, the so-called PeriFilter® that will hit the market within the next few weeks. This offers many heretofore technological and economic advantages in the separation of solid phases from liquid phases with concomitant transformation of the solid phases into processable forms for further usage and/or products.  It may be used in the separation of solids from liquids in water purification and in wastewater treatment applications as well.

  2. Article: UV Light — A Brighter Disinfection Alternative
    Through many decades of research and development, UV (ultraviolet) disinfection technology has seen significant advances in the types of water that can be treated, the operation and maintenance of the UV equipment, and the overall cost effectiveness of a UV system. By: Rob Jansen, Kenny Khoo, and Regan Thompson, Trojan Technologies
  3. N-Pumps Resolve Clogging Problems, Reduce Energy Consumption

    In the past, a lift station operation in Ohio had to send crews out daily to unclog one or more pump stations in the county service area. Chronic blockages were attributed to pump design, byproduct grease from restaurants, and medical waste from assisted living and nursing homes along the lines.

  4. 3M™ Liqui-Cel™ Membrane Degassing Modules Improve Ice Production At The Ice Palace In Moscow

    An innovative approach to high quality ice production has been adopted by the new Ice Palace in Moscow.

  5. A Guide To Eliminating Pipe Breaks

    Call it what you want, but a busted pipe spells nothing but T-R-O-U-B-L-E.

  6. Reducing Odor & Corrosion

    Veolia faced the daunting challenge of managing two large WWTP’s as well as finding a better and more cost effective solution for odor and corrosion control.

  7. Why We Should Use Naturally Occurring Microbes To Save Our Waterways

    The most common technologies utilized in the treatment of natural bodies of water that become polluted, or begin to undergo eutrophication, involve primarily some form of physical or chemical treatment such as chemical oxidizers, flocculants, activated carbon and zeolites, and/or mechanical treatments such as dredging. The primary drawback to chemical treatments is that the treatments are based on stoichiometry or molecule to molecule interactions. As a result, they get very expensive when treating large volumes of water.

  8. Case Study: Optimizing Biological Phosphorus Removal From An AquaSBR® System
    Wastewater Treatment Plant located in Middlebury, Vermont treats domestic and industrial waste received from a local dairy and a brewery. Its original treatment system consisted of a flow-through activated sludge process with primary clarifiers, anaerobic digesters, and a four-train Rotating Biological Contactor system.
  9. Pumps Reduce Costs, Improve Reliability, And Deliver Outstanding Energy Efficiency For Ohio WWTP

    An aging lift station in Marietta, OH, was the first of 12 stations to be upgraded as part of a capital improvement plan at the city’s wastewater treatment plant (WWTP).

  10. Energy-Efficiency Showdown: A Comparison Of Aeration Technologies

    On paper and in practice, aeration options and their corresponding efficiencies are calculated and compared.
