Up Flow - Anaerobic Sludge Blanket Reactor (UASB)

Up flow anaerobic sludge blanket technology also known as UASB reactor is a form of anaerobic digester which used in wastewater treatment. It is a single tank process in which the wastewater enters the reactor from the bottom, and flows upward. A suspended sludge blanket filters treats the wastewater as the wastewater flows through it. The sludge blanket is comprised of microbial granules. The microorganisms in the sludge layer degrade organic compounds. As a result, gases (methane and carbon dioxide) are released. The rising bubbles mix the sludge without the assistance of any mechanical parts. Sloped walls deflect material downwards that reaches the top of the tank. The clarified effluent is extracted from the top of the tank in an area above the sloped walls. 

FEATURES:

1. High reduction in organics.
2. Low sludge production
3. Biogas can be used for energy
