ADI® Sequencing Batch Reactor (SBR)

Description

Activated sludge process where various treatment events occur in a single vessel.

With the ADI® SBR, process events are separated by time rather than space, making it easy for operators to add, lengthen, shorten, or alter the sequence of the different events to achieve a desired process modification. The technology is suited for all types of applications, and can be used as a stand-alone process or to polish anaerobic effluent. It pairs well with ADI-BVF® reactor​, as the level variation and flow equalization offered by the BVF® system complements the batch operation of the SBR.

  • Different environments are created in the SBR by controlling process equipment such as aerators, mixers, pumps, and decanters during a specific timed cycle. By linking a programmable logic controller (P+K261LC) to the system, the process is easily monitored and controlled on-site by plant personnel. The timing and sequencing of events in an SBR cycle depend on the influent wastewater characteristics and treatment objectives. The batch kinetics with adjustable process event times result in extra flexibility compared to conventional activated sludge systems.
  • Produces high-quality effluent low in BOD, TSS, nitrogen, and phosphorus
  • Batch kinetics for removal of organics, solids, and nutrients
  • Time and sequence of process events can be easily adjusted
  • Allows for nutrient removal
  • Cyclic feast-famine conditions produce a better settling sludge than continuous-flow conditions
  • Intuitive interface offers greater flexibility and control
  • ADI Systems’ air seal decanter (ASD) mechanism has fewer mechanical parts and offers simpler construction and maintenance than most commercially available decanters
