In the BIOPAQ®UASB bioreactor, organic compounds are converted to biogas by bacteria in the absence of air. In this way, effluent discharge costs are reduced and at the same time green energy is produced.
The Upflow Anaerobic Sludge Blanket (UASB) process is a frequently applied method in the biological treatment of industrial effluents. Paques has applied the BIOPAQ®UASB technology for more than twenty years and has standardized the reactor into a modular system. Nearly four thousand BIOPAQ® modules are in operation worldwide, treating 1,760,000 m3 of effluent per day. One module has a capacity equivalent to about 1 tonne COD/day (e.g., 15 - 20 m3/hr). This modular approach allows to configure any specific layout and capacity requirement.
BIOPAQ®UASB technology is applied to treat a large variety of industrial and municipal effluents from food, beer, and beverage to pulp & paper, chemical and municipal sewage. The modules are available through a worldwide network of licensees.
Additionally, a retrofit programme is available for existing UASB installations. Paques not only has a lot of experience in updating Paques’ installations, but also in improving products of other suppliers.
