Biostyr - the compact biofiltration technology :

• Biostyr is a simple and innovative process, capable of removing all biological pollution at minimal operating costs.
• Biostyr is capable of eliminating all biodegradable pollutants, from carbon (COD and BOD) to nitrogen (N-NH4 and N-NO3) and particulates (TSS).
• The Biostyr processes modular design is easily adaptable to any kind of biological wastewater treatment.
• The Biostyr process is adaptable to meet the required effluent standards in order to satisfy the customer's need.

Biostyr biofiltration combines in a single structure:

• a biological reactor to degrade soluble pollutants and
• a separation phase to remove biomass and particulate pollutants

Advanced biological treatment

• The possibility of eliminating carbon and nitrogen within the same cell,
• High concentration of biomass on the media,
• Proven efficiency during high variations of load and f.ow rate.

Highly efficient filtration

• No final clarification is needed,
• Excellent capture of suspended solids due to filtration in a direction which compacts the media rather than expanding it.
• Filtration rate between 6 and 30 m/h, depending on application,
• Automated biofilter control system

An intelligent, compact design

• Floating media in conjunction with an upflow system
• Easy access for nozzles maintenance with no need to empty the media,
• Protection of components sensitive to clogging
• (:-ozz>s :n c:or::ac:'. w:l:- trciaU1:: wale1:),
• Wash water reservoir in the top of the niters without a separate storage tank,
• Modular design of the aeration grid, depending on application.

High quality material for the BIOSTYRENE beads

• Synthetic and light,
• Spherical and regular,
• Resistant to abrasion,
• From to 3 to 5 mm in diameter depending on the purpose of treatment,
• High specific surface for biomass adhesion

Veolia Water Solutions & Technologies has more than 20 years experience of supplying and operation BAFF {Biological Activated Flooded Filter) processes in the municipal wastewater and industrial markets. From this extensive experience we are able to offer our BIOSTYR process for applications ranging from carbonaceous removal to post-denitrification.

Highly compact, BIOSTYR combines in a single structure the biodegradation of carbonaceous and nitrogenous pollution (nitrification - denitrification) and the clarification of effluent by filtration through a media bed that acts as an environment for biological activity.
