Anaerobic Digester for Biogas Plant

by Center Enamel Co,.Ltd     based in Guangzhou, CHINA

Glass fused to steel tank is made by a special process, called vitreous enamel coating ,which is an advanced technology for anti-corrosion purpose of steel plate. Tanks are coated both inside and outside with enamel .Today, glass fused to steel tank is widely used in wastewater treatment projects as aerobic and anaerobic reactors of UASB,EGSB,SBR,BAF,USR,CSTR, and equalization tank, clarifier, and sludge holding tank. It has proven its superior resistance to thermal and chemical when facing water with extremes in pH and temperature.

Wastewater treatment solutions for anaerobic sludge digestion sector

by QM Environmental Services Ltd.     based in The Hague, NETHERLANDS

Anaerobic digestion is a series of processes in which microorganisms break down biodegradable material in the absence of oxygen, used for industrial or domestic purposes to manage waste and/or to release energy. It is widely used as part of the process to treat wastewater, like Upflow Anaerobic Sludge Blanket (UASB) reactors. As part of an integrated waste management system, anaerobic digestion reduces the emission of landfill gas into the atmosphere. Anaerobic digestion is widely used as a renewable energy source because the process produces a methane and carbon dioxide rich biogas suitable for energy production, helping to replace fossil fuels. The nutrient-rich digestate which is also produced can be used as fertilizer. The digestion process begins with bacterial hydrolysis of the input materials in order to break down insoluble organic polymers such as carbohydrates and make them available for other bacteria. Acidogenic bacteria then convert the sugars and amino acids into carbon dioxide, hydrogen, ammonia, and organic acids. Acetogenic bacteria then convert these resulting organic acids into acetic acid, along with additional ammonia, hydrogen, and carbon dioxide. Finally, methanogens convert these products to methane and carbon dioxide.

Biogas recovery

by Geomembrane Technologies Inc. (GTI)     based in Fredericton, NEW BRUNSWICK (CANADA)

Collect valuable biogas from anaerobic digestion systems with a GTI gas collection cover. In waste-to-energy projects, the collected biogas can be used as a renewable fuel to generate process heat or electricity, helping to offset energy costs.

Biogas Monitoring for the Renewable Energy Industry

by AppliTek NV - Environmental Analysis Division     based in Nazareth, BELGIUM

AppliTek`s solutions in this field concentrate on the process efficiency of anaerobic digesters. Many existing digesters give unnecessary problems, which arise due to inadequacies in the process or process control system. AppliTek has developed a unique instrument to measure and control the key processes in the anaerobic fermentation. Compact gas analyzers with proprietary technology can be implemented to check the biogas yield.

Sensor for Biogas

by Edinburgh Instruments Ltd     based in Livingston, UNITED KINGDOM

Anaerobic Digestion plants produce various gas components from a source material (or feedstock) that can be composed either solely or as a mixture of slurries, purpose-grown crops, food and organic waste material. The composition of the gas produced varies depending upon the feedstock and the Anaerobic digestion process itself. As a consequence, it is normal to measure various components of the resultant gas produced to evaluate the efficiency of the Anaerobic Digestion process. Furthermore, due to the flammable nature of Methane (CH4), and the risk of asphyxiation, most plants feature ambient air monitoring to protect personnel from any unplanned accumulation of leaked gas. CH4 is the gas component fuel, which is the intended end product of the anaerobic digestion process. In biogas plants, the concentration of CH4 in a working plant varies between 50%-75%, which is well above the Upper Explosive Limit (UEL).
