Bicom - Biwater's Compact Wastewater Treatment Plant 

Biwater Compact Wastewater Treatment Plant (Bicom) has been developed to provide an economical, simple and reliable method of treatment for wastewater. The sewage treatment is based on the activated sludge process using extended aeration and optional denitrification.

The design is standardised on a range of prefabricated factory built modules to enable rapid onsite installation.

There are seven standard model sizes catering for a population equivalent range of 5,000 to 80,000. Populations for larger communities are catered for with a combination of standard models.

Bicom is offered across two ranges, Carbonaceous or Nutrient removal models. The selection of the model required is based on the sewage characteristics and the required effluent standard with both capable of removing TSS.  The Carbonaceous model is primarily designed to biologically reduce BOD and COD, while the Nutrient removal model is designed to also reduce Nitrogen and Phosphorous in the effluent.  

To find out more about Bicom and the model ranges offered, download the Bicom brochure.

Specific benefits:

  • Total wastewater solution
  • Consistent high quality effluent that fulfils EU discharge consents
  • Designed and built to British / EU / AWWA Standards
  • Compact plant reducing footprint
  • Rapid installation with prefabricated factory built and tested modules 

General features:

  • Modular approach allows flexibility to achieve the client specific requirements
  • Process selection capable of dealing with varying hydraulic and pollution loads
  • Proven, simple and reliable process elements
  • No primary settlement required
  • Reduced quantity of stable sludge produced with optional sludge treatment units 


Bicom typical flow schematic:

Biwater have the in-house capability to provide 3D modelling of the proposed Bicom system in the chosen location, as seen in these examples, which enable the client the benefit of visualising the wastewater treatment solution and how it aligns to their requirements.

Biwater provide a full engineering service. In providing the Bicom total wastewater solution, the engineering services will include developed of the system and submission of detailed information, based on the available data for each specific project location.
