  • Financing an anaerobic digester

    LENDERS are generally well disposed to projects that diversify revenues while lowering costs and mitigating risks. Add a ready source of equity and you are well on the way toward financing a project that is a win-win proposition for the lender and the project developer. Such is the case with the anaerobic digester project at Geerlings Hillside Farm (GHF). The Geerlings's 8,000-head hog farm is ...

  • Anaerobic digestion of macroalgae: methane potentials, pre-treatment, inhibition and co-digestion

    In the present study we tested four macroalgae species – harvested in Denmark – for their suitability of bioconversion to methane. In batch experiments (53 °C) methane yields varied from 132 ml g volatile solids−1 (VS) for Gracillaria vermiculophylla, 152 ml g VS−1 for Ulva lactuca, 166 ml g VS−1 for Chaetomorpha linum and 340 ml g VS−1 for Saccharina ...

  • Peristaltic Pumps excel in Anaerobic Digestion & Biogas applications

    Biogas is a natural gas also known as biofuel or biomass and is produced by breaking down organic material such as household waste, manure and crops grown specifically for biofuel with temperature-sensitive microbes and capturing the by-products. In practice, it is difficult to find a pumping system for this application. Why? The pumps needs to handle fluid media as well as gas parts ...

  • Toronto moves forward with anaerobic digestion of residential SSO

    In June 2007, Toronto's City Council approved the “Target 70” plan to achieve 70 percent diversion by 2010. Target 70 includes construction of two, 55,000 metric tons/year anaerobic digestion plants to process residential source separated organics (SSO). City Council says that the digester facilities, along with adoption of single stream recycling and a pay-as-you-throw funding system, will ...

  • 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 ...

  • Enhanced anaerobic digestion of waste activated sludge of low organic content in a novel digester

    A novel digester, termed an internal circulation anaerobic digester (ICAD), was developed to intensify sludge digestion. It consists of reaction zone, settling zone, thickening zone, riser and downcomer. Internal circulation in the digester is intensified by backflow biogas. The mesophilic ICAD treating thermal pretreated waste activated sludge with volatile suspended solids (VSS)/suspended ...

  • Low energy mixing to optimize anaerobic digestion at the Kitchener WWTP

    The existing Kitchener Wastewater Treatment Plant (WWTP) is a conventional secondary treatment facility, with a rated capacity of 122,745 mVd. The plant is comprised of two separate secondary treatment plants (Plant 1 and Plant 2) served by a common headworks facilities and primary clarifier facilities. Plant 1 was constructed in the early 1960s and Plant 2 was constructed in the mid-1970s. Both ...
