  • National brewery benefits from biogas

    Anheuser-Busch has installed anaerobic digestion systems at 10 of its 12 large breweries in the U.S., with an 11th system in design. Primary drivers are cost-avoidance for wastewater treatment fees and fossil fuel purchases. ANHEUSER-BUSCH, owner of 12 large breweries in the U.S., has committed to reduce its greenhouse gas emissions 5 percent from 2005 levels by 2010. The company is well ...

  • Increasing biogas yield through addition of food waste

    1. Introduction The Moosburg wastewater treatment plant has one 634,008 gallons anaerobic digester, which was designed to process a maximum 23,775 gallons/day of activated sludge at 3.5% solids. The AD is currently processing 17,170 gallons/day of sludge and producing 39decatherms/day of energy from biogas. The operators would like to better utilize their anaerobic ...

  • The feasibility of trace element supplementation for stable operation of wheat stillage-fed biogas tank reactors

    The aim of this study was to investigate the effect of trace element supplementation on operation of wheat stillage-fed biogas tank reactors. The stillage used was a residue from bio-ethanol production, containing high levels of sulfate. In biogas production, high sulfate content has been associated with poor process stability in terms of low methane production and accumulation of process ...

  • Enhancement of hydrogen production from Kitchen Waste using heat treated anaerobic biogas plant slurry with pH control

    Hydrogen is found to be a clean energy source; biohydrogen has been researched in recent years. Anaerobic Digestion of Kitchen Waste (KW) for hydrogen production was performed in lab scale reactors, using heat-treated anaerobically digested biogas plant slurry. The biogas plant slurry was given heat treatment at varying temperatures ranging from 70 to 100 ° C for 15 min. Enhancement of hydrogen ...

  • Anaerobic co-digestion of surplus yeast and wastewater to increase energy recovery in breweries

    Surplus yeast is a residue produced during brewery process, which presents high contents of organic matter. Biogas production from yeast could significantly contribute to bioenergy production in breweries, via biogas generation. Co-digestion of surplus yeast and brewery wastewater in a single treatment step would simplify the technical and economical requirements for the transformation of both ...

  • Bio hydrogen production from kitchen waste

    The hydrogen producing organisms such as Escherichia coli (E.Coli), Enterobacter cloacae, Hafnia alvei, Citrobacter freundii, Serratia marcescens and Clostridium acetobutylicum strains were isolated from the sludge of biogas plant. The hydrogen producing efficiency of isolated organisms from kitchen waste were examined under anaerobic conditions. Lab scale studies were conducted under controlled ...

  • Biomineralisation of dye waste in a two-phase hybrid UASB reactor using starch effluent as a co-substrate

    Starch and dye wastes have wide variation in their characteristics were treated on combination; this new technology supports the effective utilisation of starch waste in destruction of dyes. In this investigation, a lab-scale two-phase HUASBR was used at ambient temperature. After start-up, the dye and starch effluent were mixed at different proportions and fed into the reactor. The reactor was ...

  • Waterschapsbedrijf Limburg (WBL) - case study

    Along with WBL Sustec has tested and lab researched  the continuous thermal hydrolysis of the surplusslib of the wastewater treatment plants Hoensbroek and Venlo. On this basis is determined the most optimal hydrolysis method. Then for nine months on pilot scale tests were carried out to the thermal hydrolysis and fermentation of the surplusslib. The tests confirmed that by thermal ...

  • Full-stream and part-stream ultrasound treatment effect on sludge anaerobic digestion

    The use of ultrasound as pre-treatment to improve anaerobic digestion of secondary sludge has been established as a promising technology. There are great differences between lab scale and full-scale devices, regarding the relationship between the disintegration achieved and the energy supplied. Based on economic aspects, most of the full-scale plants use partial-stream instead of the full-stream ...

  • Sulfide removal from industrial wastewaters by lithotrophic denitrification using nitrate as an electron acceptor

    Sulfide is present in wastewaters as well as in biogas and can be removed by several physicochemical and biotechnological processes. Nitrate is a potential electron acceptor, readily available in most wastewater treatment plants and it can replace oxygen under anoxic conditions. A lab-scale reactor was operated for treatment of sulfide containing wastewater with nitrate as an electron acceptor ...

  • Low temperature microwave and conventional heating pre-treatments to improve sludge anaerobic biodegradability

    This paper presents the results of lab-scale experiments on low temperature thermal pre-treatment (less than 100 °C) prior to anaerobic digestion of sewage sludge. Two heating ways, microwave heating (MH) and conventional heating (CH), and two types of sludge, primary and waste activated sludge, were compared under the same experimental conditions. The degree of solubilisation produced by ...

  • 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 ...
