JIPL offers the complete SBR system solution from INVENT, which includes process guarantees – JIPL / INVENT takes responsibility for the entire scope of the SBR delivery.
The Sequencing Batch Reactor (SBR) is an activated sludge process designed to operate under non-steady state conditions. An SBR operates in a true batch mode with aeration and sludge settlement both occurring in the same tank. The major differences between SBR and conventional continuous-flow activated sludge system is that the SBR tank carries out the functions of equalization, aeration and sedimentation in a time sequence rather than in the conventional space sequence of continuous-flow systems. In addition, the SBR system can be designed with the ability to treat a wide range of influent volumes whereas the continuous system is based upon a fixed influent flow rate. Thus, there is a degree of flexibility associated with working in a time rather than in a space sequence.
SBRs produce sludges with good settling properties provided the influent wastewater is admitted into the aeration in a controlled manner.
Advantages
The INVENT SBR System offers a range of unique advantages, such as:
- High process stability independent from flow and load fluctuations
- Better control over filamentous growth and settling problems due to excellent mixing and integrated selector effect
- No sludge recycle system is required
- No clarifiers are required
- Small footprint
- Unique HYPERCLASSIC Mixer/Aerator which combines excellent mixing and aeration in one machine
- Fluid mechanically optimized INVENT Decanting System
- Less equipment
- Simple control schemes
- Flexible design and operational strategies
INVENT SBR Process:
Fill: wastewater enters the reactor basin and mixes with activated sludge mixed liquor held in the tank.
React: aeration of the tank contents. Biological reactions occur until the desired degree of treatment has been achieved.
Settle: aeration is stopped and the activated sludge suspended solids settle to form a blanket on the bottom of the reactor.
Decant: clarified effluent is removed from the reactor without disturbing the sludge blanket.
Idle: unexpired time between cycles. Surplus sludge wasting may occur.
