The hydraulic retention time in the reactor was calculated to be 22,9 hours and the sludge was removed from the digestors every 14 days. The reactor was monitored regularly over a period of 25 weeks from March through August with ambient temperatures ranging from 12 to 38 C. This technology is promissing however more research has to be done to verify the behavior of the reactor during winter conditions. Verifications have also to be made for very cold temperature that can be observed in many areas in Canada.
