Bavaria - Case Study
Over 25 years of smoothly running wastewater treatment at a brewery
In 1984, Dutch beer brewer Bavaria needed to increase its wastewater treatment capacity. Paques installed a BIOPAQ®UASB to its existing aerobic clarification plant, reducing aerobic sludge and aeration cost.
Over 25 years later, the installation still runs smoothly and treats 10,000 kg COD every day whilst generating 350 m3 biogas per day. In 2004 Bavaria wanted to remove hydrogen sulphide from the biogas and Paques installed a THIOPAQ® gas scrubber. The installation removes 25 kg of sulphur daily, after which the biogas is ready for the gas engine to generate electricity and heat (about 500 kWe per day).
