  • How big is the distributed energy opportunity for water and wastewater utilities?

    Energy costs for water utilities are large, and growing Energy is a significant cost for many water utilities, and costs are growing as more energy-intensive forms of water supply, including desalination, are being used. Energy is typically the second-largest utility budget item in developed countries, after labour. In many developing countries, energy can account for 70% or even more, of ...

  • Alternatives for energy production in aerobic wastewater treatment facilities

    Using technologies such as anaerobic digestion for energy generation from wastewater demands a change in infrastructure that several treatment works are not prepared to immediately implement. This works explores the use of energy production technologies to increase the sustainability of conventional aerobic wastewater treatment plants. The first option considered sludge (a by-product from ...

  • Energy consumption model for wastewater treatment process control

    Wastewater treatment must satisfy discharge requirements under specified constraints and have minimal operating costs (OC). The operating results of wastewater treatment processes (WWTPs) have significantly focused on both the energy consumption (EC) and effluent quality (EQ). To reflect the relationship between the EC and EQ of WWTPs directly, an extended Elman neural network-based energy ...

  • Multiphase pumps for energy-efficient water and wastewater treatment

    Multiphase pumps are unique products with outstanding features compared to conventional centrifugal pumps. The approach consists of using the pumps not only for transport of liquids but also for partial gas supply and as dynamic mixer for gas enrichment. Therefore this novel pump conception barely has ...

  • Pumps for energy-efficient water and wastewater treatment

    Multiphase pumps are unique products with outstanding features compared to conventional centrifugal pumps. The approach consists of using the pumps not only for transport of liquids but also for partial gas supply and as dynamic mixer for gas enrichment. Therefore this novel pump conception barely has something in common with a standard pump. Even the mode of ...

  • Energy Recovery in Urban Wastewater Treatment on Global Scale

    ABSTRACT The lack of proper wastewater treatment results in production of CO2 and CH4 without the opportunity for carbon sequestration and energy recovery, with deleterious effects for global warming. Without extending wastewater treatment to all urban areas worldwide, CO2 and CH4 emissions associated with wastewater discharges could reach the equivalent of 3.13·105 tCO2·d-1 in 2025, with ...

  • Energy recovery from thermal treatment of dewatered sludge in wastewater treatment plants

    Sewage sludge is a by-product generated from municipal wastewater treatment (WWT) processes. This study examines the conversion of sludge via energy recovery from gasification/combustion for thermal treatment of dewatered sludge. The present analysis is based on a chemical equilibrium model of thermal conversion of previously dewatered sludge with moisture content of 60–80%. Prior to ...

  • Integrating anaerobic processes into wastewater treatment

    Over the past decade, the concept of anaerobic processes for the treatment of low temperature domestic wastewater has been introduced. This paper uses a developed wastewater flowsheet model and experimental data from several pilot scale studies to establish the impact of integrating anaerobic process into the wastewater flowsheet. The results demonstrate that, by integrating an expanded granular ...
