• Primary Sludge stage with an integrated pre-buffer
• Activated Sludge stage in sequencing batch operation (SBR chamber)
• Settling stage in the SBR chamber to deposit suspended solids
• Clarified water decantated to the filter feed tank auto valve or pump
• Filtration process occurs in the final stage with proper disinfection.

Advantages

• Advanced technology in the water treatment plants
• Less foot print compare to FBBR process
• Operating flexibility and control.
• Potential capital cost savings by eliminating clarifiers and other equipment.
