Biosep™ for Municipalities

Biosep™ is a membranes bioreactor developed by Veolia. It is an activated sludge process in which membranes provide the clarification.

Biosep™ is suitable for municipal clients who:

Must adhere to high discharge standards (environmentally sensitive areas)
Want to achieve high wastewater treatment efficiency
Have a limited area to operate in
Want to reuse water for irrigation, for use in sprinkler systems or for recharging aquifers

Biosep™ is ideal for meeting the requirements of municipal clients who experience sharp seasonal load variations (touristic areas). Biosep™ also enables the purified water to be released directly back into environmentally sensitive areas, thereby avoiding the construction of long outfalls.

Advantages of the Biosep™ Process for Municipal Clients:

Membranes provide clarification; the load applied can be significantly higher than in a classic activated sludge. For the same load, the reactor is smaller so, the plant is more compact
Thanks to its compactness, the structure can be easily confined, and odor and noise nuisances are controlled
On mixed wastewater, Biosep™ is free of risks related to fibrous sludge bulking
By undergoing an additional UV treatment, the water treated by Biosep™ can be reused in irrigation, sprinkler systems or for recharging aquifers
Biosep™ is ideal when refurbishing existing sites, thanks to its compact design and the fact that it can be easily installed in existing tanks

Features & Benefits

Biosep™ provides water of exceptional quality:

High reduction of carbon and nitrogen pollution
High suspended matter removal
High bacteria removal rate

Biosep™ has many advantages compared with conventional biological treatment of effluents by activated sludge:

Compact system
No final clarification (no risk of sludge loss, performance is independent of the sludge index)
With a similar load, the biological reactor is smaller
High COD removal, including slowly biodegradable COD thanks to a high "sludge age" and membrane separation
Reduced reagent consumption in phosphorus elimination
Thickener may also be removed because of the high concentration reached in the biological reactor
