CSBR™ is a water treatment process that achieves continuous flow by improving batch operation flow of conventional SBR (Sequencing Batch Reactor) process.
A2O activated sludge process with continuous process flow is arranged in the first stage.
Two series of SBR system, maintaining a fixed water level, are arranged at the end of A2O process.
CFR (Continuos Flow Reactor) Cell is part of A2O process that maintains continuous flow with anoxic, anaerobic and aerobic zone in the first stage, and two SBRreactors in a row alternatively in the second stage.
The influent undergoes anaerobic/aerobic reaction from organic decomposition process and flows into the lower water level SBR tanks - in which sedimentation and supernatant discharge occurs.
The influent is mixed with sludge and undergoes SBR reaction with aerobic, anaerobic and sedimentation processes - therefore biodegradation is once again performed.
The microbial sludge is discharged to the outside through the thickened return activated sludge (TRAS) system on the bottom of SBR tank, where sedimentation occurs.
The remaining sludge is mixed with the influent of the previous stage and the process is repeated in bioreactors.
Major Features of CSBR
*BNR : Biological Nutrient Removal
CSBR™ adapts a hydraulic decanter system using pressure of air blower achieving
maintenance-free guarantee in whole life cycle of the plant.
The patent of continuous SBR system was granted to Aqua Aerobic in the United
States in 1993 by Peter Timpany and co-inventor Mark Lansdell, as registered
