Autothermal Thermophilic Aerobic Digestion (ATAD)

With Autothermal Thermophilic Aerobic Digestion (ATAD) from FUCHS, sewage sludge is not only stabilized but also disinfected. It becomes a valuable and cost-effective fertilizer that meets the highest international quality requirements (Class A according to US EPA 503). Besides municipal sludge, industrial sewage sludge and liquid manure can also be treated in an ATAD plant.

The aerobic thermophilic process (temperature range 50–60 °C) allows short reaction times, which minimizes the space required and therefore the investment costs of sludge treatment. The stable process and the robust FUCHS machinery result in reliable operation and simple handling.

Through continuous development, the FUCHS ATAD concept has been steadily improved. The combination of increased oxygen transfer at the beginning of the process and the use of the latest exhaust air treatment technology has made the FUCHS ATAD even more effective. The first FUCHS ATAD plant was built back in 1977 and is still in operation. Benefit from our many years of experience in aerobic sewage sludge treatment.
