PISCES™ CFSBR Continuous Fill Sequencing Batch Reactor


Parkson’s PISCES™ CFSBR combines the process benefits of cyclical treatment with the simplified operating concept of continuously filling all reactor tanks at all times.

Flow is split evenly to all tanks utilizing a splitter box with manual valves, eliminating the need for cycling automatic valves to control influent. Anoxic and anaerobic fill conditions for filamentous control and nutrient removal are achieved during settle and decant when aeration is turned off, yet flow is still entering the reactors. An underflow baffle provides a barrier between the influent entry point and the main react zone where the decanter is located, allowing settle and decant to occur under quiescent conditions.

The Parkson Advantages:

  • Choice of aeration type
    • VariOx™ jet aeration
    • RetrievOx™ retrievable diffusers
    • Fixed diffusers (fine and coarse bubble)
  • Decanter with no in-basin motors or drives
  • Dynamic control that preserves aeration steps better than systems with pre-programmed storm modes
  • Unparalleled customer support and service
