Company location: United Kingdom


The AFS sequencing batch reactor has been proven through many applications to be a reliable, economic and long-term solution for the treatment of leachate derived from municipal solid waste.

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:

  1. Tank filling
  2. Aeration
  3. Settlement discharge
  4. Sludge withdrawal
  5. Standby


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