  • A perfect pair: SBR designs & advanced aeration technology

    Conventional sequencing batch reactors (SBRs) that utilize diffused-air networks have existed in the U.S. for about three decades now. The reliability of controls and instrumentation has significantly improved in the last 10 to 15 years, and as a result, SBR plant designs are becoming more widely accepted. The attractiveness of their compact layout and ease of operation has also helped increase ...

  • Dynamic Draft Tube – Deep Oxidation Ditch Technology

    Deep oxidation ditches and aeration basins are beneficial, permitting more water to be processed on a given surface area. However, standard vertical shaft aeration rotors limit oxidation ditches and aeration basins to an operating depth of no more than 4.5 meters (15 feet). The Dynamic Draft Tube Aeration Rotor overcomes the shortcomings of existing aeration rotors permitting operation of ...

  • Case study - Built for generations

    When building a wastewater treatment facility in 1984 officials in a Wisconsin village decided on an oxidation ditch design and chose Aire-O2®Aspirator aerators based on their flexibility and energy efficiency. Today, several of those aerators are still in use and the treatment facility operates at even more ...

  • Case study - SBR keeps noise, energy & capital costs low

    Pennsylvania is home to one of the first Argos® SBR plants to utilize a surface mounted process aerator/mixer, which is a significant improvement over the traditional diffused air network designs. The new layout offers substantial capital investment savings as well as significant reductions in ...

  • Vibration – What is It? How does it Affect My Operation? What can I Do About It?

    ABSTRACTThis paper describes how pump vibration can create problems in conveyance systems. Potential sources of vibration are reviewed as well as factors that affect pump vibration. Examples are presented that demonstrate pump vibration problems: (1) when a wet well level was lowered to obtain system storage capacity, (2) in a new installation, and (3) when one pump in an installation functioned ...

  • SolarBee Technical Bulletin

    A. SOLARBEE OVERVIEW 1. Origin of the SolarBee. Pump Systems, Inc. (PSI) developed, built and installed its first solar powered mixer in Dickinson, ND, in the summer of 1998. It was installed into a 30 acre x 13 foot deep municipal wastewater reservoir which had a long history of toxicity associated with ammonia, odor, and stratification problems. In six weeks the entire reservoir cleared up to ...
