Internal circulation reactor
- Internal circulation reactor
The internal circulation reactor (IC reactor) is a form of anaerobic digester. It is primarily designed to treat wastewater. The IC reactor is an evolution of the UASB and EGSB digestion systems. The digester typically produces biogas with a high concentration methane (c80%). In essence the IC reactor appears similar to two UASB reactors stacked on top of themselves, with internal ciculation of wastewaters to improve digestion rates and gas yields. The foot print for the IC reactor is therefore typically smaller however it is taller due to the increased complexity of the reactor.
The IC reactor typically comes as part of a two stage anaerobic digestion system where it is preceded by an acidification and hydrolysis tank. Effluent leaving the IC reactor will often require aerobic treatment to reduce biochemical oxygen demand (BOD) and COD to discharge consent levels.
