  • DAF Regnerative Turbine Aeration Technology

    Gas is dissolved into a fluid through pressure in any DAF application.  The regenerative turbine pump applies pressure through a triple action force (centrifugal, axial and friction) to the gas and fluid during a single pass through the pump head.  Whether disolving compressed or atmospheric air, nitrogen or other gases to the fluid, the regenerative turbine pump achieves the highest ...

  • Addressing digester foaming by fixing activated sludge system and gaining capacity in both

    The City of Richland Wastewater Treatment Facility digesters have experienced Nocardiainduced digester foaming problems from the time they went into operation in 1985. Because of the persistent foam, most or all of the thickened waste activated sludge (TWAS) was often not sent to the digesters but directly to the belt filter press to be dewatered separately from the digested sludge. It was ...

  • 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 ...

  • High-strength wastes boost biogas production

    Water and wastewater treatment plants (WWTP) are significant consumers of energy. The U.S. Environmental Protection Agency estimates the industry uses the equivalent of 56 billion kilowatt hours (kWh) of electricity, representing three percent of the nation’s energy consumption, and is responsible for creating 45 million tons of greenhouse gas emissions each year. Energy intensive processes, such ...
