  • Addressing food waste through anaerobic digestion

    Food waste continues to be a problem worldwide, even with more and more attention being paid to reducing spoilage and to salvaging edible foods for redistribution or reuse. One approach to the problem is diverting inedible organic matter from landfills and treating it with anaerobic digestion, which has the side effect of capturing energy. The amount of food wasted worldwide was 2.3 billion ...

  • 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. ...

  • Anaerobic Digestion—What Are the Economics?

    Although solid waste AD facilities are just starting to emerge, haulers and their customers may see some benefits if the development trend continues. A Pro Forma Model objective can be constructed for strategic planning of an anaerobic digestion facility. Anaerobic digestion (AD) of food wastes in the U.S. is a developing market that is poised for continued growth in many regions. ...

  • 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 ...

  • 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 ...

  • 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 ...


  • Bintulu Anaerobic Digestion Plant Now Complete

    BIODOME® ASIA, part of KIRK GROUP, has recently completed a state-of-the-art anaerobic digestion plant in East Malaysia for our client Kubota Corporation, consisting of the largest digester tank ever built by KIRK to date which has a capacity in excess of ...

  • 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 ...

  • Implementation of the anaerobic digestion model (ADM1) in the PHREEQC chemistry engine

    Anaerobic digestion is state-of-the-art technology to treat sludge and effluents from various industries. Modelling and optimisation of digestion operations can be advantageously performed using the anaerobic digestion model (ADM1) from the International Water Association. The ADM1, however, lacks a proper physico-chemical framework, which makes it difficult to consider wastewater of complex ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...
