  • 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 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 ...

  • Biological Wastewater Treatment

    Untitled Document The use of microorganisms to remove contaminants from wastewater is effective and widespread. To choose the right system from the many options offered, ...


  • Picture Perfect Wastewater Treatment

    At first, Hollywood and wastewater treatment may seem like an unlikely pair. But the City of San Diego Metropolitan Wastewater Department’s (MWWD) Metro Biosolids Center (MBC) is an uncommon place. From serving as a two-time movie set to winning awards for striking architectural design, the MBC has been recognized as an industry leader in creative thinking, community involvement and ...

  • Wastewater Treatment in Turbo Mode

    Sulzer turbocompressors type ABS HST are successful in wastewater treatment. Today, 2000 units are installed around the world—for example, in municipal plants like in the city of Sögel, Germany. Here, the turbocompressors not only reduced the operating costs but also helped the plant to cope with load fluctuations. The secret behind this success is an advanced design with proven ...

  • Distillery Wastewater Treatment and Disposal

    Untitled Document ABSTRACT 1. One of the most important environmental problems faced by the world is management of wastes. Industrial processes create a variety ...


  • What Is Industrial Wastewater Treatment?

    Industrial progress has helped economic and social growth to a large extent, whereas, it has also created the major problem of environmental pollution at the same time as well. Industrial pollution is one of the major concerns of industries and environment protection agencies worldwide. The technical advantages have assisted the industries to reduce water pollution to a certain level. ...

  • 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 ...

  • Energetic flexibility on wastewater treatment plants

    In the future, an additional potential of control reserve as well as storage capacities will be required to compensate fluctuating renewable energy availability. The operation of energy systems will change and flexibility in energy generation and consumption will rise to a valuable asset. Wastewater treatment plants (WWTPs) are capable of providing the flexibility needed, not only with their ...

  • Metal treatment facility eliminates wastewater

    The Facility A specialty metals facility located in Euclid, Ohio rolls, forms, cuts and presses specialty metals for the aircraft and aerospace, auto and electrical industries. This plant specializes in high value molybdenum and tungsten, as well as copper parts. The Problem As a result of the metal rinsing processes in the facility discharged water into ...

  • Sustainability of decentralized wastewater treatment technologies

    In many Countries, small communities are required to treat wastewater discharges to increasing standards of lesser environmental impacts, but must achieve that goal at locally sustainable costs. While biological membrane treatment (membrane bio-reactors (MBRs)) is quickly becoming the industry standard for centralized wastewater treatment plants, and would also be ideally suited also for small ...
