  • Maximize Your Recycled Water Distribution through Technical Customer Service

    The Inland Empire Utilities Agency (IEUA), a municipal water district in southern California, provides high quality recycled water for landscape, agricultural, and industrial uses. Two industrial customers, an electrical power generating station and a textile dyeing company, required special efforts to address their recycled water quality needs. The electrical power generating station faced the ...

  • Producing green energy from post-consumer solid food wastes at a wastewater treatment plant using an innovative new process

    ABSTRACT More than 246 million tons of municipal solid waste (MSW) was generated in the United States in 2005, and this tonnage is expected to increase every year. The third highest component of MSW is food waste, but less than 3% of food waste is recycled. In an effort to meet the U.S. Environmental Protection Agency’s national 35% MSW recycling goal, and many states’ and local governments’ ...

  • Does the recycling of waste streams from drinking water treatment plants worsen the quality of finished water? A case assessment in China

    The overall purpose was to assess the feasibilities of recycling filter backwash water (FBWW) and combined filter backwash water (CFBWW) in a drinking water treatment plant in south China. The variations of regular water-quality indexes, metal indexes (Al, Mn and Cd), polyacrylamide and disinfection by-product indexes (trihalomethanes and their formation potentials) along with the treatment ...

  • A Comparison of Operating Strategies – Chlorine vs UV

    ABSTRACTCity of Scott’s Valley owns and operates a 1.5 mgd activated sludge wastewater treatment plant. Currently about 0.3 mgd of the secondary effluent is diverted to the recycled water facility. Two chlorine disinfection alternatives (both using liquid sodium hypochlorite) and UV disinfection were considered to all the facility to achieve high level (Title 22) disinfection requirements from ...

  • Probabilistic analysis of fluorescence signals for monitoring dual reticulation water recycling schemes

    Improved techniques are required for the detection of inadvertent cross-connections between recycled water and potable water systems in dual reticulation schemes. The aim of this research was to assess the potential for fluorescence spectroscopy to be developed as a tool to distinguish recycled water from potable water. Weekly grab samples of recycled and potable water were obtained over 12 weeks ...
