Sequential Batch Reactor (SBR)

A reliable, cost-effective choice for treating domestic and industrial wastewater.

Centurion’s Sequential Batch Reactor (SBR) systems are a reliable, cost-effective choice for treating domestic and industrial wastewater.

They are built on well-established technology that’s easy for plant operators to run, making it ideal for remote or low-maintenance sites.

Why Choose a Centurion Sequential Batch Reactor System?
  • Consistently meets key discharge targets for BOD, TSS, nitrogen, phosphorus, and E. coli
  • Simple, operator-friendly controls
  • Low maintenance design with minimal moving parts
  • Flexible construction – available in mild steel (with PU/polyurea epoxy), panel liner tanks, or SS316, depending on site conditions
  • Factory-built and tested for fast site installation
  • Can easily add polishing filtration (media-filtration or ultra-filtration) to achieve Medium and High risk treated effluent
How the Sequential Batch Reactor System works

SBR systems treat wastewater in five automated steps:

  • Fill – wastewater enters the reactor tank
  • React – anoxic and aerobic phases remove BOD and nitrogen
  • Settle – solids settle to the bottom
  • Decant – clean effluent is drawn off
  • Idle – system resets for the next cycle.

All that’s needed onsite is a connection to the inlet screen and power to the control panel - fast, efficient, and ready to go.

Table 1 shows the typical influent and treated effluent concentrations that our Sequential Batch Reactor can achieve, demonstrating effective removal of solids, nutrients and pathogens.
