Sequencing batch reactor process - DegremontĀ®

general. The sequencing batch reactor process ( SBR) involves a single complete mix type reactor in which aeration takes place followed by clarification, whence the designation "sequential".Sludge settles when aeration is shut down and a drainage mechanism used to draw off the supernatant liquor.

Sequencing batch reactor - Wikipedia

Sequencing batch reactors (SBR) or sequential batch reactors are a type of activated sludge process for the treatment of wastewater.SBR reactors treat wastewater such as sewage or output from anaerobic digesters or mechanical biological treatment facilities in batches. Oxygen is bubbled through the mixture of wastewater and activated sludge to reduce the organic matter (measured as .
