Scope of supply

Dreher Breweries produces and distributes bottled, canned and draught beer in Budapest. UTB built the wastewater plant turnkey: drum filtration, buffering and two-stage biological treatment: a UASB anaerobic stage followed by an aerobic stage. The biogas from the anaerobic system is burned in a boiler and returned to the brewery as steam. Closed reactors and a biofilter keep the plant inside strict noise and odour limits.
