Industrial effluent treatment is considered an effective way to control costs, improve efficiencies and to comply with industry standards and effluent discharge limits. Restrictions related to lack of space or to other factors, do however, prevent the treatment of effluent on site for many companies. With the development of high rate Internal Circulation (IC) reactors, BIOPAQ® provides an opportunity for industries with limited available space to treat their effluent, and in addition, both noise and odor issues have been addressed. Efficiently designed industrial IC effluent treatment, built to suit existing circumstances, has now become a proven technology, with hundreds of examples worldwide in various industrial sectors.

BIOPAQ® IC Reactor
The BIOPAQ® IC (Internal Circulation) technology is an advanced anaerobic treatment technology that is applicable for the treatment of certain high strength organic wastewaters, and builds upon the design concepts of the UASB.

BIOPAQ® UASB Reactor
The BIOPAQ® UASB Reactor uses the Upflow Anaerobic Sludge Blanket (UASB) treatment concept whereby a dense blanket of granular anaerobic biomass is employed to bring about the conversion of organic compounds that are passed through the sludge blanket on a continuous basis. Typical conversion rates lie in the 8-12 kg COD/m3.d range.  Biogas produced from the liquid effluent phase is separated and collected at the top of the reactor.
