  • What`s New? Biogas Power

    Technologies that connect the biogas line to the power line include cooling and clean up components, microturbines and reciprocating gas engines and control systems. TOP BILLING on the biogas to electricity stage typically goes to the microturbines and reciprocating gas engines. But in the theater of renewable energy from organics recycling, the show can’t go on without the supporting cast of gas ...

  • High-strength wastes boost biogas production

    Water and wastewater treatment plants (WWTP) are significant consumers of energy. The U.S. Environmental Protection Agency estimates the industry uses the equivalent of 56 billion kilowatt hours (kWh) of electricity, representing three percent of the nation’s energy consumption, and is responsible for creating 45 million tons of greenhouse gas emissions each year. Energy intensive processes, such ...

  • Three stages MBR (methanogenic, aerobic biofilm and membrane filtration) for the treatment of low-strength wastewaters

    The use of a new three stages MBR process with a first methanogenic UASB stage, a second stage with aerobic biofilm growing on small carrier elements maintained in suspension and third stage with membrane filtration module is presented. The objective of the first methanogenic chamber is to diminish COD of the raw wastewater, producing a biogas rich in methane, and decrease the sludge production. ...

  • Performance results of the treatment of stillage using two-stage anaerobic digestion coupled to membrane filtration at different operating conditions

    The production of ethanol is results in generation of large amounts of liquid residue (stillage). Anaerobic membrane bioreactors (AnMBRs) are a promising technology primarily for the treatment of high strength wastewater, having lower energy requirements as compared to aerobic ones and higher effluent quality as compared to conventional anaerobic reactors. AnMBR applied to stillage treatment ...

  • Odour control on waste water treatment plants and pumping stations using DMT biotrickling filtration

    Lengthy detention times and warm weather / climate leads to septic waste water producing copious amounts of not only hydrogen sulphide, but also ammonia, organic sulphides, mercaptans, bringing numerous odour complaints on waste water treatment plants ( WWTP’s ) and pumping stations. An odour abatement unit therefore will have to treat not only hydrogen sulphide, but also other pollutants ...

  • Evaluation of sanitation and wastewater treatment technologies: case studies from India

    This paper reports about the results of an evaluation of selected sanitation systems in India. The following sanitation systems were evaluated: septic tanks, communal Ecosan systems, biogas toilets, solid immobilized biofilters, multiple stage filtration and decentralized wastewater treatment systems (DEWATS). The evaluation has been based on an initial assessment looking at whether the systems ...

  • 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 ...

  • Sewage pre-concentration for maximum recovery and reuse at decentralized level

    Pre-concentration of municipal wastewater by chemically enhanced primary treatment (CEPT) was studied under controlled laboratory conditions. Both iron and aluminium-based coagulants were examined at gradually increasing concentrations (0.23, 0.35, 0.70 and 1.05 mmol/L). The CEPT sludge generated from different coagulation experiments was digested in batch anaerobic reactors, while the ...

  • Pollutant removal and membrane fouling in an anaerobic submerged membrane bioreactor for real sewage treatment

    Real sewage was continuously treated by a laboratory-scale anaerobic submerged membrane bioreactor (AnSMBR) for over 160 days. Results showed that around 90% of chemical oxygen demand, and 99% of turbidity and total suspended solids in the sewage could be removed by the AnSMBR system. Membrane flux sustained at 11 L/(m2 h) was realized with biogas sparging. Small flocs from sludge ...

  • 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 ...

  • Laboratory-scale membrane up-concentration and co-anaerobic digestion for energy recovery from sewage and kitchen waste

    This study assessed an alternative concept for co-treatment of sewage and organic kitchen waste in Vietnam. The goal was to apply direct membrane filtration for sewage treatment to generate a permeate that is suitable for discharge. The obtained chemical oxygen demand (COD) concentrations in the permeate of ultrafiltration tests were indeed under the limit value (50 mg/L) of the local ...

  • Wastewater treatment in an anaerobic filter using small lava stones as filter media without temperature control

    For their simplicity and using cheap support materials, biological filtration of municipal wastewater can be adequate for developing countries where the legislation is not as strict as in other countries, like the members of the European Union. Biological filters are fixed biomass reactors where the suspended pollutants can easily be retained and the dissolved substances can be transformed by ...

  • Energy from wastewater How breweries can tap undiscovered energy resources

    The fact that beer is a nourishing energy supplier was known to beer-brewing monks as early as the Middle Ages. After all, it also had to act as food during the hard times of Lent. However, the fact that this beverage, which is popular throughout the world, could become an energy supplier for the brewery and the environment in the course of the manufacturing process – to be exact, during ...
