  • High performance biogas plants for organics waste diversion

    Wild fluctuations in prices for agricultural products and mushrooming prices for energy can greatly influence the economics of biogas plants. Long term reliable profitability calculations are becoming increasingly difficult. Generally speaking, however, rising energy prices have a positive effect on the economics of well designed biogas projects. By selecting low cost feedstock, the profitability ...

  • Allweiler Peristaltic Pumps: an ingenious solution for biogas plants

    Installations and plants used to process biomass for the production of biofuels must be capable of handling difficult conditions. For example, intermediate products in the production of biodiesel exhibit a high level of chemical aggressiveness. Accordingly, pumps, pipe connections, and fittings must be capable of resisting these demanding conditions. In addition, waste products usually contain a ...

  • Comparison of different conditions, substrates and operation modes by dynamic simulation of a full-scale anaerobic SBR plant

    Simulation studies for a full-scale anaerobic unit of a wastewater treatment plant (WWTP) were performed using the anaerobic digestion model no. 1 (ADM1). The anaerobic full-scale plant consists of one mesophilic and one thermophilic digester, operated in an anaerobic sequential batch reactor (ASBR) mode, and sludge enrichment reactors (SER) for each digester. The digesters are fed with a mixture ...

  • Latest analytical technology ensures biogas efficiency

    Anaerobic Digestion (AD) relies on the ability of specific micro-organisms to convert organic material into a gas that can be used to generate electricity. However, these bacteria require specific conditions if they are to function effectively and instrumentation specialist company HACH LANGE has developed a range of online, portable and laboratory instruments that have enabled a large number of ...


  • 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 ...

  • Kickoff for Biogas - South America Opts for Green Energy Made by WELTEC

    Currently, the world is locked on to the FIFA World Cup in Brazil. Though they have already reached a high technical level as far as football is concerned, the South American countries still have development potential in the fields of biogas technology and renewable energies. In the interview, Aguinaldo Ramalho of the German biogas plant manufacturer WELTEC BIOPOWER talks about the potential, ...

  • 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 ...

  • Spatial diffusion of biogas technology in Switzerland: a GIS-based multi-agent simulation approach

    In this paper, we study the viability and spatial diffusion of agricultural biogas technology in Switzerland by means of a multi-agent simulation model. The simulation process displays the estimated dissemination of biogas technology in the different regions of Switzerland over the period from 2006 to 2025, taking the varying circumstances for biogas use in each region explicitly into account. ...

  • Anaerobic Digestion of Semi-Solid Organic Waste Under Identical Technical Setting but Different Bacteria Inoculums and Purification of the Biogas Produced

    Abstract The main objective of the present research paper is to compare the amount of biogas produced from a set of experiments conducted under identical technical setting (loading rate, temperature, means of stirring, kind of substrate fed, hydraulic retention time, etc.), using orthofruit waste but different bacteria inoculums. Methane concentration in the biogas, total COD and volatile solids ...


  • Anaerobic co-digestion of sewage sludge and primary clarifier skimmings for increased biogas production

    The objective of the study was to identify the impact of co-digesting clarifier skimmings on the overall methane generation from the treatment plant and additional energy value of the increased methane production. Biogas production from co-digesting clarifier skimmings and sewage sludge in pilot-scale fed-batch mesophilic anaerobic digesters has been evaluated. The digester was fed with ...

  • Energy self-sufficient sewage wastewater treatment plants: is optimized anaerobic sludge digestion the key?

    The anaerobic digestion of primary and waste activated sludge generates biogas that can be converted into energy to power the operation of a sewage wastewater treatment plant (WWTP). But can the biogas generated by anaerobic sludge digestion ever completely satisfy the electricity requirements of a WWTP with ‘standard’ energy consumption (i.e. industrial pollution not treated, no ...

  • From fermentation residues to nutrient concentrate

    Treatment of fermentation residue substrates from biogas plants by means of ceramic membranes The growing number of biogas plants makes it increasingly difficult to return the fermentation residue substrates to green spaces or arable land. Especially large-scale plants are often unable to find sufficient disposal possibilities in acceptable distances. Therefore it is sensible to treat ...

  • From fermentation residues to nutrient concentrate

    The growing number of bio-gas plants makes it in-creasingly difficult to return the fermentation residue substrates to green spaces or arable land. Especially large-scale plants are often unable to find sufficient disposal possibilities in acceptable distances. Therefore it is sensible to treat fermentation residue substrates by suitable screening processes in such a way that they can be ...
