Anaerobic techniques (in absence of oxygen) to eliminate the organic pollution. During this process, biogas is generated that can be used as fuel. Other advantages of the anaerobic techniques are: the extremely low excess sludge production (up to 10 times less than the aerobic plant), the moderate operating costs, and the compactness. Anaerobic techniques allow for treating wastewater with a high organic load. They are also used to relieve existing aerobic plants, such as when extending the production.   In the anaerobic field, TDFC can propose different reactor types, based on its long experience: form the compact UASB to the multipurpose UACF, an hybrid type improved by TDFC providing a more stable treatment and a final effluent of higher quality. For some complex wastewater, the hybrid systems are the only feasible anaerobic solution.     << Back
