A Sequencing Batch Reactor (SBR) is a relatively low technology aeration method comprising a system of one or more tanks, typically GRP glass-lined metal or concrete in construction, containing pumping and aeration equipment.

The process consists of five defined stages:

  • Tank filling
  • Aeration
  • Settlement discharge
  • Sludge withdrawal
  • Standby

Each tank is sized to give a balance between oxygen transfer, energy and heat conversion, and maintenance requirements.

  • Simple, reliable low maintenance process.
  • Scope for thermal insulation to permit all weather operation in cold climates.
  • Low operational cost.
  • Ability to withstand shock loads.
  • Ability to deal with heavy metals and other toxic components
