Automatic Decanter Helps SBR Performance
SBR decanter
Cheneng FCP decanter is a key equipment for SBR process, in SBR
process continuous inflow and treatment is accommodated through
alternating react, settle,and decant sequences in SBR trains. Each
train, through a typically operating cycle of three to five hours,
provides all of the processes of activated sludge treatment in one
basin.
Advantages of SBR
Enhanced Treatment Performance
Superior sludge settling performance due to bio-selector and
aerobic/anoxic/anaerobic cyclic sequences
Suppress filamentous bacteria thus lower potential for sludge
bulking
Enhanced nutrient removal (Denitrification and Bio-P) without
chemicals or separate tanks
Built-in equalization capacity preventing performance deterioration
during surge conditions
Smaller Footprint and Lower Construction Cost
Equalization, biological treatment, and clarification achieved in
one tank
No external return sludge pumping system
Rectangular tanks with common-wall design
Simple process, fast construction and installation
Flexibility
Duration of cycle or sequences can be adjusted to accommodate
variation in hydraulic flow or biological loading, e.g. shorter
cycle for peak flow conditions or shorter aeration time for lower
loading
Easy expansion with single rectangular tank design
Automatic control system provides easy and flexible adjustment to
operational parameters
Low Operation and Maintenance Cost
Better aeration control, denitrification, and lower power
consumption
Less and simpler equipment, thus reduced maintenance
Automatic control adapting to changing conditions with less
operator attention
Biological N and P removal without need for chemicals
