UASB Anaerobic Reactor

The UASB reactor wastewater is introduced as uniformly as possible into the bottom of the reactor, and the wastewater passes upward through a sludge bed containing granular sludge or flocculent sludge. Anaerobic reactions occur in the process of contact between wastewater and sludge particles. The biogas produced in the anaerobic state (mainly methane and carbon dioxide) causes an internal circulation, which is beneficial for the formation and maintenance of granular sludge. Some of the gas formed in the sludge layer adheres to the sludge particles, and the attached and non-attached gas rises to the top of the reactor. The sludge rising to the surface hits the bottom of the gas emitter of the three-phase reactor, causing degassing of the sludge flocs with attached gas bubbles. After the bubbles are released, the sludge particles will settle to the surface of the sludge bed, and the attached and unattached gases are collected in the plenum of the three-phase separator at the top of the reactor.
