Our SBR is not just another SBR...See the difference by yourself!

Recognizing the fact that the performance of a SBR reactor is closely tied to the performance of its living biomass, it becomes obvious that a particular SBR concept will provide specific performances.

NOMINAL EFFLUENT QUALITY OF SBR SYSTEMS

TYPE 1:	RAPID-FILL/ FULL-BATCH SBR (RFB)
Reinforced, 100% time driven biological controls. Fill time: ~10% of cycle	BOD5 TSS NH3 NO3 ** Pt * Pt	5 - 10 mg/L 5 - 10 mg/L < 5 mg/L < 5 mg/L 1.0 - 2.0 mg/L 0.4 - 1.0 mg/L
TYPE 2:	GRADUAL-FILL/ SEMI-BATCH SBR (GF-SB)
Weakened, flow driven biological controls. Fill time: 50% of cycle	BOD5 TSS NH3 NO3 Pt	15 - 20 mg/L 15 - 20 mg/L 5 - 10 mg/L 5 - 10 mg/L 2 - 3 mg/L
TYPE 3:	CONTINUOUS-FILL/ SEQUENCE-OPERATED SYSTEM (CF-SO)
Modified CAS***, 100% flow driven. Fill time: 100% of cycle	BOD5 TSS NH3 NO3 Pt	20 - 30 mg/L 20 - 30 mg/L 5 - 10 mg/L 5 - 10 mg/L 2 - 4 mg/L
TYPE 4:	GRADUAL-FILL / FULL-BATCH SBR (GFB)
Flow driven biological controls reinforced with high strength wastewater. Fill time: 50-80% of cycle Application: Concentrated industrial wastewater	BOD5 SS NH3 NO3 ** Pt * Pt	10 - 30 mg/L 10 - 30 mg/L 5 - 10 mg/L 5 - 10 mg/L 0.5 - 5 mg/L 2 - 10 mg/L

NOTES:
1.These values are not absolute but are relative values generally observed and expected from domestic wastewater treatment when the system is under full load.

* Value considering equalization alone
