  • Wastewater Treatment Works

    Margate and Broadstairs, two of the principal towns in northeastern Kent, attract thousands of visitors each summer to enjoy the beaches and countryside within easy reach of London. Such popularity comes with a cost. The infrastructure serving the area needs to be developed to keep pace with the rising population and the requirements of new UK and European Union legislation. With the ...

  • Milk Processing Wastewater Treatment

    A milk processing facility was using a 800 hp evaporator to dispose of their 0.75% solids concentrated milk waste stream. The staff was interested in evaluating the effect of using the Floccin products to capture the majority of the BOD and send this higher % solids/BOD sludge to the evaporator. The idea was to reduce the electric hp by reducing the volume of water going to the evaporator. Their ...

  • Decentralized wastewater treatment using a bioelectrochemical system to produce methane and electricity

    Biological electrochemical systems (BESs) have the potential for decentralized treatment in developing countries. A 46 L, two-chamber, hydraulically partitioned microbial fuel cell (MFC) was designed to replicate low-flow scenarios leaving a composting toilet. The co-evolution of electricity and methane in this MFC was evaluated by testing two distinct waste streams: synthetic feces (Case F) ...

  • 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 ...

  • Wastewater-Primary Treatment

    Primary Treatment is defined as a wastewater treatment process that takes place in a rectangular or circular tank and allows those substances in wastewater that readily settle or float to be separated from the water being treated. This process achieves solids separation. The solids readily available to settle to achieve sedimentation will do so in a settling tank referred as a clarifier. On the ...

  • Wastewater treatment and electricity generation by membrane less microbial fuel

    Membrane less microbial fuel cell (ML-MFC) is one of the attractive approaches for the simultaneous electricity generation and wastewater treatment. In this present paper, electricity generation by ML-MFC has been studied in continuous mode. Several experiments such as effect of aeration in cathode compartment, sludge concentration, initial substrate concentration and the COD removing capability ...

  • 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 ...

  • 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 ...

  • Application Focus: Biological Wastewater Treatment

    In knowing the size and health of the active biomass population in a wastewater treatment process, cause-and-effect relationships can then be established with process variables. If a change in the process is beneficial or detrimental to the population, ATP results will indicate to what degree the population is helped or harmed by the change. Since ATP measurements isolate the living population, ...

  • Treatment of wastewater from anaerobic digestion

    The Client The customer is power plant which produces biogas from biomass and sewage farm, through anaerobic digestion and thermal recovery, located nearby Munich in Germany. The Client’s needs Biogas is produced by the fermentation of organic substances of animal and vegetal origin in absence of oxygen (anaerobic process). This process produces a ...

  • Application of LEDs in Wastewater Treatment Plants

    Wastewater treatment plants are prone to explosive risks due to the presence of volatile, flammable compounds inside the building. The Occupational Safety and Health Administration (OSHA) has highlighted the dangers of such hazardous environments through a federal safety investigation of a Canastota wastewater plant. In 2014, a worker died from third-degree burns after a devastating ...

  • Microalgae as a sustainable alternative for wastewater treatment

    Thanks to the threats posed to human health and the environment, and the economic costs of its treatment, wastewater from domestic, industrial and agricultural processes has been considered a serious problem for a long time. However, a paradigm shift in the past few years has led to a new concept of wastewater, not as a problem but as a source of energy and other precious resources, including ...

  • Operating a two-stage microbial fuel cell–constructed wetland for fuller wastewater treatment and more efficient electricity generation

    By integrating microbial fuel cells (MFCs) into constructed wetlands (CWs) the need and cost of building a reactor are eliminated, while CWs provide the simultaneous redox conditions required for optimum MFC performance. Two single-stage MFC-CWs, with dewatered alum sludge cake as the main wetland medium for enhanced phosphorus removal, were operated to determine the effects of electrode ...

  • Performance of air-cathode stacked microbial fuel cells systems for wastewater treatment and electricity production

    Two different air-cathode stacked microbial fuel cell (MFC) configurations were evaluated under continuous flow during the treatment of municipal wastewater and electricity production at a hydraulic retention time (HRT) of 3, 1, and 0.5 d. Stacked MFC 1 was formed by 20 individual air-cathode MFC units. The second stacked MFC (stacked MFC 2) consisted of 40 air-cathode MFC units placed in a ...

  • Impact of the As Samra wastewater treatment plant upgrade on the water quality (COD, electrical conductivity, TP, TN) of the Zarqa River

    The impact of the As Samra wastewater treatment plant upgrade on the quality of the Zarqa River (ZR) water was investigated. Time series data that extend from October 2005 until December 2009 obtained by a state-of-the-art telemetric monitoring system were analyzed at two monitoring stations located 4 to 5 km downstream of the As Samra effluent confluence with the Zarqa River and about 25 km ...

  • Biogas production and potential from U.S. Wastewater Treatment

    How many wastewater treatment plants (WWTPs) have anaerobic digestion? How many are utilizing the biogas? What percentage of these facilities are feeding additional substrates into their digesters? How is the biogas being used — is it flared, used to drive process machinery, heat the digester, or injected into a natural gas pipeline? These are some of the questions asked of the ...

  • Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

    Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...
