The Bio-Pure Flowpath was developed for Commercial, Industrial or larger off sewage mains applications.

It uses proven SAF (submerged aerated filter) technology for maximum performance and reliability, using the most reliable energy efficient aeration blowers with a prolonged integral flow path system to maximise effluent retention time and quality.

The standard plant range offers treatment to a 30mg/l BOD: 20mg/l SS effluent quality standard with options for 30mg/l NH3 effluent quality.

All our treatment plants are designed in accordance with the British Water Code of Practice for flows and loads, the Bio-Pure FlowPath range can be designed to meet your population requirements.

The plants can be single or modular tanks depending on population and consent requirements.  They are designed to be installed underground.

Key benefits:

  • Easy to install
  • Energy efficient air blower for lower running costs
  • SAF technology with reliable performance
  • Typical de-sludge period is approximately 12 months dependant on usage

How it works:

The Bio-Pure Flowpath commercial sewage treatment plant contains, a two stage primary settlement zone designed to settle coarse and non-biological loadings.

Sludge will build up in these zones and require moving periodically.

The Settled effluent will then discharge forward into the bio-zones. Each segment field contains a high percentage of filter media, where biological treatment performs, due to a high oxygen input.

Once treatment has taken place the multiple bio-zones, the effluent is discharged into the final humus tank, where it settles before flowing via the outlet.

Occasionally an amount of settled humus sludge is returned to the first primary zone.
