  • Anaerobic digestion in the United Kingdom

    Anaerobic digestion (AD) has been used to treat sewage sludge by the United Kingdom’s (UK) water industry for over 100 years. More recent years have seen a revolution as AD has swiftly expanded into agricultural feedstocks and food waste. Data from the Waste Resource and Action Programme (WRAP) shows that in the past year alone, there has been a 46 percent growth in the size of the sector. ...

  • Winery and distillery wastewater treatment by anaerobic digestion

    ABSTRACTAnaerobic digestion is widely used for wastewater treatment, especially in the food industries. Generally after the anaerobic treatment there is an aerobic post-treatment in order to return the treated water to nature. Several technologies are applied for winery wastewater treatment. They are using free cells or flocs (anaerobic contact digesters, anaerobic sequencing batch reactors and ...

  • The Effect of the Microsludgetm Treatment Process on Anaerobic Digestion Performance

    ABSTRACT Thickened waste activated sludge (TWAS) from biological treatment processes is less amenable to anaerobic digestion than primary sludge. This is due to TWAS being composed mostly of cellular material and extracellular polymeric substances (EPS) instead of more easily digestible carbohydrates and fats that are typically found in primary sludge. In an attempt to improve TWAS digestion ...

  • Waste treatment Wernsing Anaerobic Digestion Plant (Germany)

    Wernsing biogas plant Addrup The Wernsing biogas plant was one of the first biogas weser-ems plants to treat waste from food industry since its commission in 2001. Up to 200 tonnes of white cabbage and potatoes waste are used as main input material per day. In addition to the biogas plant, the facilities owned by the Wernsing group include a waste water treatment plant to treat the sewage ...

  • Anaerobic digestion system for dairy farm wastes

    On of the critical problems in dairy farms is the management of animal wastes. The first negative impact of manure and other animal wastes is emission of malodor and air pollutants and furthermore attraction of insects that may correspond to spreading of pathogens and emerging epidemic diseases. The secondary impacts of un-controlled release of manure and animal wastes are pollution of soil and ...


  • Modelling anaerobic digestion of concentrated black water and faecal matter in accumulation system

    A dynamic mathematical model based on anaerobic digestion model no. 1 (ADM1) was developed for accumulation (AC) system treating concentrated black water and faecal matter at different temperatures. The AC system was investigated for the treatment of waste(water) produced from the following systems: vacuum toilet for black water (VBW), vacuum toilet for faeces with urine separation (VF), dry ...

  • Fate of phosphorus during anaerobic digestion of sludge from an EBPR plant

    As part of their ongoing commitment to produce safe sewage sludge for recycling to agricultural land, Anglian Water are expanding their enhanced sludge treatment operations at four key sites across the Eastern region. The project at Whitlingham STW uses thermal hydrolysis as a pre-treatment to anaerobic digestion as the main sludge treatment process. As well as producing an enhanced treated ...

  • Effect of Microsludge on Anaerobic Digester Performance and Residuals Dewatering at La County’s JWPCP

    MicroSludge™ is a patented chemical and pressure pretreatment process that liquefies waste activated sludge (WAS) to increase both the rate and extent that it is degraded in a conventional mesophilic anaerobic digester (CMAD). The process uses chemical pretreatment to weaken cell membranes and a high-pressure homogenizer, or “celldisrupter”, to provide an enormous and sudden pressure change to ...

  • Two-phase anaerobic digestion for class a biosolids at moccasin bend WWTP

    The Moccasin Bend Wastewater Treatment Plant (WWTP) provides treatment for the City of Chattanooga, Tennessee and the surrounding region. The City has completed upgrades to the solids handling facilities to treat and dewater the primary solids and waste activated sludge (WAS) from the WWTP. This paper summarizes the process to handle the primary solids and the start-up process. Primary solids ...

  • A modified anaerobic digestion process with chemical sludge pre-treatment and its modelling

    Activated Sludge Models (ASMs) assume an unbiodegradable organic particulate fraction in the activated sludge, which is derived from the decay of active microorganisms in the sludge and/or introduced from wastewater. In this study, a seasonal change of such activated sludge constituents in a municipal wastewater treatment plant was monitored for 1.5 years. The chemical oxygen demand ratio of the ...

  • Thermal hydrolysis pre-treatment for high solids anaerobic digestion

    The City and County of San Francisco completed a two-year pilot study of pre-treatment processes to mesophilic anaerobic digestion for improved biosolids stabilization and production of biosolids suitable for unrestricted reuse (class A biosolids). The results of this effort will help in the design of the new Solids Handling Facility (SHF) at the 11 m3/s Southeast Water Pollution Control Plant ...

  • Climate change impacts of food waste diversion to anaerobic digesters

    Treating food waste (FW) by anaerobic digestion to recover biogas and biofertiliser is a fantastic opportunity. The biogas is renewable, base-load, non-fossil energy. Using the digestate on land as biofertiliser completes nutrient cycles and conserves soil organic matter. The Part-503 rules protect health and the environment. Existing sludge digesters can be ‘turbo-charged’ by retrofitting ...

  • Implications of full-scale implementation of an anammox-based process as post-treatment of a municipal anaerobic sludge digester operated with co-digestion

    The feasibility of treating the supernatant of a municipal sludge digester supplemented with co-substrates by means of an anammox-based process (ELAN®) was tested in Guillarei (NW of Spain). Ammonia concentration measured in the supernatant of the sludge digester varied in the range 800–1,500 g N/m3 due to the fact that the sludge produced in the plant was co-digested with ...
