  • An Infrastructure Grows · Decentralized Treatment and Recycling Domestic Wastewater

    THE TERM, “decentralized waste-water management,” refers to the process of treating and discharging treated wastewater in the local vicinity where it is generated. Decentralized systems typically use the soil as the final receptor of the treated wastewater instead of discharging to surface waters, which are generally the receptors of treated wastewater from larger centralized treatment plants. ...


  • Advanced Enviro - Septic™ Wastewater Treatment System Septic Tank Effluent Filters and Charco al (Odor) Filters NOT Recommended

    Abstract: Effluent filters are installed in the outlet from the septic tank with the intended purpose of retaining solids inside the tank, preventing them from entering the treatment system and/or dispersal field. The concern is that if solids escape from the septic tank, they could cause clogging of the system components or the soil interface. While this may be a legitimate concern for some ...

    The Cheyenne Board of Public Utilities (BOPU) operates the water and wastewater systems for the capital of Wyoming which has a population of more than 63,000. Located in the fast growing Front Range Urban Corridor, BOPU is challenged by growth, periodic water scarcity and aging infrastructure. During high demand, Cheyenne disinfects approximately 2 million gallons from well fields at an ...

  • Innovative use of silvichemical biomass and its derivatives for heavy metal sorption from wastewater

    Biosorption is a process of metabolism-independent, passive, physico-chemical binding of metal ions involving non-living biomass, which offers advantages over conventional methods because of cost-effectiveness, especially for dilute metal solutions, and minimal environmental impact. This paper reviews heavy metal biosorption using silvichemical-based biomass materials. It discusses the use of a ...

  • Design, Construction, and Startup of Sustainable and Integrated Wetlands Treatment Process in Stockton, California

    ABSTRACTConstructed treatment wetlands have become an established technology for treatment of municipal and industrial wastewaters around the world. Wetland systems can provide treatment similar to conventional tertiary wastewater facilities if sufficient land is available but with lower energy and maintenance requirements. Ancillary benefits of treatment wetlands include wildlife habitat, ...

  • Sustainable, Low-maintenance Disinfection for Onsite Systems

    Most of the regulations applicable for onsite wastewater treatment system are based on the use of native soil for effluent dispersal. However, there are more and more situations where dispersal of effluent in native soil is impossible: repairs of existing systems on undersized lots for implementation of required dispersal fields: sites located in soils having low permeability: or where the ...
