Treatment of wastewater from anaerobic digestion
The Client The customer is power plant which produces biogas from biomass and sewage farm, through anaerobic digestion and thermal recovery, located nearby Munich in Germany. The Client’s needs Biogas is produced by the fermentation of organic substances of animal and vegetal origin in absence of oxygen (anaerobic process). This process produces a stream called digestate which is an ...

The MBR for biological desulfurization of biogas the BioReactor with the DMT BioSulfurex HCP process
Abstract DMT has developed a process for biological desulfurization at low pH for the treatment of biogas. This process (BioSulfurex®) is pH, temperature, nutrient and oxygen controlled. During an intensive research period the elimination capacity (EC) and removal efficiencies (RE) at different process conditions were determined. The effect of variations in H2S loading, cleaning procedures ...

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 The ...

Biogas desulfurization and biogas upgrading using a hybrid membrane system – modeling study
Membrane gas permeation using glassy membranes proved to be a suitable method for biogas upgrading and natural gas substitute production on account of low energy consumption and high compactness. Glassy membranes are very effective in the separation of bulk carbon dioxide and water from a methane-containing stream. However, the content of hydrogen sulfide can be lowered only partially. This ...

The hydrolysis and biogas production of complex cellulosic substrates using three anaerobic biomass sources
In this study, the ability of various sludges to digest a diverse range of cellulose and cellulose-derived substrates was assessed at different temperatures to elucidate the factors affecting hydrolysis. For this purpose, the biogas production was monitored and the specific biogas activity (SBA) of the sludges was employed to compare the performance of three anaerobic sludges on the degradation ...

Biomethane enters the gas grid article for energy world
The Carbon Plan, published in 2011, aims to reduce UK carbon emissions by a quarter from 1990 levels. With the current policies in place, the UK is on target to reduce emissions by over a third by 2020 and with the introduction of new technologies this should increase to an 80% reduction by 2050. However, currently around half the UK’s carbon emissions result from heat related processes and ...

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 digester to achieve energy ...

Biogas as an option for industrial applications
Biogas is typically burned to produce electricity or used as vehicle fuel. This case study analyses possibilities to utilise biogas directly in industrial applications to replace current fossil raw materials. True industrial cases are analysed by considering economic impacts of using either landfill gas or gas produced from biomass. Utilisation of biogas is economically viable and technically ...

Cleaning biogas with bacteria
Organic materials added to an anaerobic digester commonly contain sulphur components. During the anaerobic digestion process, the sulphur is converted into hydrogen sulphide (H2S), which is absorbed by the biogas. When the biogas produced in an AD plant goes on to be combusted in a gas engine or boiler, the H2S will give off sulphur dioxide (SO2) and sulphuric acid (H2SO4). It is for this reason ...

Bio-SNG featured in energy world in February 2011
The use of bio-fuels for heating and lighting pre-dates the use of fossil fuels by thousands of years. However, unlike with fossil fuels, a systematic knowledge of the challenges posed by solid bio-fuels is not as widely understood, a fact attributable to the exponential acceleration of fossil fuel usage as global demand increased during the industrial revolution. In the wake of this, producers ...
