AAT BIOGAS Technology

Reliable Technology for commercial success

AAT offers plant design, process technology and equipment for processing of organic waste and purification of highly contaminated waste water with simultaneous energy production. 


Skelleftea (Sweden)

New agitator technology

The biogas plant of Skelleftea in Sweden has been fundamentally improved.

With our partner Cellwood Machinery we brought the pre-treatment and the agitator technology up-to-date.
From now on there will be treated 20 tons of bio waste per day through a pulper which rejects disturbing matter like plastic, sand and anorganic matter.
The existing digesters have been equipped with an AAT-vertical agitator as well as three vertical agitators "Bart" made in stainless steel.
