Hydraulic digester

The AAT hydraulic digester produces more gas for almost zero operation costs.

The AAT system creates optimal process and mixing conditions for anaerobic degradation of organic matter without moving parts placed inside the digester and without external mixing energy.

By separating the digester into a main and secondary compartment with an integrated substrate recycle a process environment ideal for anaerobic bacteria is created.

Special design features provide dilution of scum and sediment layer as well as mechanical scum and sediment destruction.

Long plant life, minimal maintenance and operator attendance result from the fact that no moving parts are located inside the digester.
