FRP Roof 3,450N/Cm Anaerobic Digester Tank 18000m3

Anaerobic Digester Tanks

Anaerobic digesters are widely used as a renewable energy source, and the biogas produced by the process consists of methane, carbon dioxide, hydrogen sulfide, and trace amounts of other "polluted" gases. This biogas can be used directly in cogeneration gas engines or upgraded to natural gas-grade biomethane. The resulting nutrient-rich digestate can also be used as fertilizer.

Center Enamel can provide anaerobic digestion tanks to meet different anaerobic digestion processes. The feedstock for an anaerobic digester can come from sources such as animal manure, food processing waste, industrial wastewater treatment processes, and municipal wastewater treatment processes, almost any source that contains digestible organic waste.

The use of anaerobic digestion (AD) to treat food waste and other materials is now a mature technology used in China and many other countries around the world. Center Enamel has been in the AD field for over 30 years; we design, manufacture and install AD tanks for our customers, supporting the global challenge of reducing waste and generating more renewable green energy.
