Anaerobic Digestion Treatment
A proven and energy-efficient method to treat industrial wastewater.
What is anaerobic digestion?
Anaerobic treatment is a proven and energy-efficient method for treating industrial wastewater. It uses anaerobic bacteria (biomass) to convert organic pollutants or COD (chemical oxygen demand) into biogas in an oxygen-free environment. Anaerobic micro-organisms (specific to oxygen-free conditions) are selected for their ability to degrade organic matter present in industrial effluents, converting organic pollutants into biogas (methane + carbon dioxide) and a small amount of biosolids. The energy-rich biogas can then be used for boiler feed and/or combined heat and power (CHP) to produce ‘green’ electricity and heat.
Anaerobic treatment offers several advantages over aerobic alternatives:
- Low energy use
- Small reactor surface area
- Lower chemical usage
- Reduced sludge-handling costs
Use aerobic treatment after anaerobic treatment to achieve a good treated-water quality for discharge into a water course.
