The BIOTIM® UASB is a reactor tank equipped with a three-phase separator on the top of the tank. The wastewater is fed at the reactor bottom through a distribution system. While flowing upwards through the dense sludge bed, the organic pollutants are converted into biomass and biogas. This biogas creates a more turbulent area above the sludge bed, called the sludge blanket.
The three-phase separator on the top of the reactor separates the biogas from the sludge and the effluent. To improve the sludge-water separation, parallel plates can be installed inside the separator to increase the settling surface area.
