  • Ethylene removal in domestic refrigerators

    Ethylene is a plant hormone produced naturally by fruit and other plant tissues. It is known as the ripening hormone because it regulates the series of processes associated with the ripening and senescence of fruit. Ethylene removal from the environment, both in storage chambers and transport containers, where it is stored in the form of gas, is a widespread practice designed to provide a ...

  • High speed municipal sewage treatment in microbial fuel cell integrated with anaerobic membrane filtration system

    A cylindrical two chambered microbial fuel cell (MFC) integrated with an anaerobic membrane filter was designed and constructed to evaluate bioelectricity generation and removal efficiency of organic substrate (glucose or domestic wastewater) depending on organic loading rates (OLRs). The MFC was continuously operated with OLRs 3.75, 5.0, 6.25, and 9.38 kg chemical oxygen demand ...

  • Primary Drinking Water from Wastewater Effluent: Pilot Test Experience at the Miami Dade South District WWTP

    ABSTRACTThe Miami-Dade Water and Sewer Department (MDWASD) owns and operates the South District wastewater Treatment Plant in Goulds, Florida. This is a 225 mgd peak flowrate secondary oxygen activated sludge treatment facility that discharges effluent via deep injection wells. Based upon the detection of nitrogen species in the monitoring wells for the deep injection well system, MDWASD entered ...

  • What is biological wastewater treatment?

    Biological wastewater treatment harnesses the action of bacteria and other microorganisms to clean water Biological wastewater treatment is a process that seems simple on the surface since it uses natural processes to help with the decomposition of organic substances, but in fact, it’s a complex, not completely understood process at the intersection of biology and ...

  • A Submerged Attached Growth Bioreactor for Decentralized Wastewater Treatment

    ABSTRACTThe Amphidrome® process is a submerged attached growth bioreactor (SAGB) that has been used in Massachusetts, Connecticut, Rhode Island and New Jersey for decentralized wastewater treatment systems ranging in size from 440 gpd to 150,000 gpd. The two primary advantages of a SAGB are the small volume requirement and the elimination of downstream clarification. Five years of data from four ...

  • Sustainable wastewater separation treatment systems coupled with nutrient and water reducing greywater reuse technologies

    Nationally and internationally, pressure is increasing to introduce nutrient reducing, water conserving and recycling measures for sustainable residential and small community water/wastewater systems. Reports of inadequate water quality and quantity are being reported daily. Over the past thirty years the federal government and State of Alaska have invested over 4 billion dollars installing piped ...


  • Process Alternative Comparisons Assisted with Biowin Modeling

    ABSTRACTPermitted at 6.4 mgd on an annual average day basis, the City of Avondale Wastewater Treatment Plant currently employs Nitrification/Denitrification process to produce effluent with maximum total nitrogen of 10 mg/L. The process consists of Aeration Basins followed by Secondary Clarifiers to treat the screened influent after the grit removal. On the solids handling side, the Wasted ...

  • Putting recycled water to use in Washington state

    The LOTT Alliance is the regional wastewater treatment system serving the cities of Lacey, Olympia, Tumwater and northern Thurston County (LOTT) in Washington State. The core of LOTT's long-range wastewater resource management plan is production of Class A Reclaimed Water, which is the highest quality of reclaimed water as designated by the Washington Departments of Health and Ecology. The ...
