AO/SBR

Overview

The AO (Anoxic-Oxic) and SBR (Sequencing Batch Reactor) processes are widely used biological wastewater treatment technologies designed for efficient organic pollutant removal and nutrient reduction. AO systems provide continuous treatment with effective nitrogen removal, while SBR systems integrate equalization, aeration, settling, and discharge in a single reactor.

Typical Applications

Range of applications

  • Municipal wastewater
  • Industrial park wastewater
  • Food processing wastewater
  • Hotel and resort wastewater
  • Community sewage treatment

Working Principle

AO Process

Wastewater passes through an anoxic zone for denitrification and then an aerobic zone for organic degradation and nitrification.

AO Working Process

SBR Process

Treatment occurs in sequential stages within one tank: Fill → React → Settle → Decant → Idle. This simplifies plant layout and operation.
