Anaerobic processes of wastewater treatment are increasingly used to improve efficiency and reduce operational costs for food industry wastewater purification.
In closed anaerobic systems organic compounds undergo decomposition in the absence of oxygen and transformation into biogas with no oxidation. The general value of COD (chemical oxygen demand) in wastewater containing organic compounds that are transformed into biogas within methane anaerobic fermentation is reduced due to COD - methane formed during purification extracted from wastewater.
Different types of biogas plants are used depending on wastewater qualitative composition (suspended solids and COD).
Detailed monitoring of wastewater composition and competent intensive engineering analysis contribute to selecting the most beneficial solution for each Customer.
