BİOSU SBR
Sequencing batch reactor — the whole treatment cycle in one tank. The most economical BİOSU model, and the most flexible against fluctuating flow.
What Is SBR?
BİOSU SBR is a sequencing batch reactor: filling, aeration, settling and decanting all take place in a single tank, one after the other. Because the plant runs in batches rather than continuously, the cycle times can be tuned to the flow — which is what makes it flexible against a variable load. It is the most economical member of the BİOSU family.
- •50 – 5,000 population equivalent
- •Design flow 5 – 500 m³/day
- •Lowest capital cost in the family
- •Nutrient removal included in the cycle
- •No separate clarifier
How It Works
- 1Fill — raw wastewater enters the reactor.
- 2React — aeration and mixing; organic load, nitrogen and phosphorus are removed in the same tank through aerobic and anoxic phases.
- 3Settle — aeration stops and the biomass settles; no separate clarifier is needed.
- 4Decant — clarified water is drawn off by decanter, and excess sludge is removed.
When SBR Is the Right Choice
Choose it when
the goal is to meet the discharge limit at the lowest investment, the flow is batch-like or fluctuating, and nitrogen and phosphorus removal is wanted within a single tank.
Look at another model when
- •The treated water will be reused — then MBR, because only the membrane barrier gives reuse quality.
- •Space is very tight — MBBR needs the smallest volume.
- •An existing aeration tank is to be upgraded rather than replaced — that is an MBBR retrofit.
Saying where a technology is not the right answer is part of the selection. The comparison across all three is on the packaged plants page.
Capacity and Effluent
Flows above this range are met with modular units in parallel or with a project-specific design. The exact model and design flow for your project are fixed with a wastewater analysis.
