ANAEROBIC DIGESTER W8

Industrial Test Capabilities

• Effluent treatability studies, including solids, carbon and biogas balances to determine purification (COD-BOD)
• Determining optimum operating temperatures, feed rates and ratios
• Observing effect of pH and influent nutrient concentration
• Process stability studies
• Determination of controlling kinetics
• 100% scale-up to industrial requirement

Practical Training Exercises

• Preparation, warming and acclimation of a anaerobic reactor
• Demonstration of the multistage nature of anaerobic digestion
• Undertaking carbon balances
• Studying effects on purification performance of Hydraulic loading, Feed ratios, Temperature, Nutrient deficiency, Influent 

Technical Details
