Types of Anaerobic Digesters

Types of Anaerobic Digesters Biogas Plant Anaerobic digesters are capable of treating insoluble wastes and soluble waste-waters. Insoluble wastes such as particulate and colloidal organics are considered to be high-strength wastes and require lengthy digestion periods for hydrolysis and solubilization. Digester retention times of at least 10–20 days are typical for high-strength wastes. High-rate anaerobic digesters are used for the treatment of soluble wastewaters. Because these wastewaters do not require hydrolysis and solubilization...
