Biosep - Membrane Bioreactor (MBR)
Overview
Effective, Compact, Easy to Use
An innovative solution developed by Veolia Water Technologies, Biosep™ combines two proven technologies:
- Biological treatment using activated sludge
- Membrane filtration
Biosep™ produces very high quality water, fully compliant with the highest standards for water reuse for irrigation and industrial applications.
With more than 120 references worldwide, Biosep™ is recommended for:
- Significant reduction of carbon, nitrogen and phosphorus pollution
- High and simultaneous removal of bacteria depending on the treated water, completed by downstream disinfection.
Veolia also offers 'Biosep™ Pack', new standard membrane filtration units:
- Flexible and modular solutions
- Guaranteed performances identical to those of the conventional Biosep™ process
Biosep™ is sold under the Neosep™ trademark in Japan, the United States, Australia and New Zealand.
Biosep™ for Industries
The Biosep™ technology meets the specific requirements of industrial clients, when they are confronted with the following problems:
- Concentrated effluents
- High discharge standards and treatment efficiency
- Upgrade/refurbish existing facilities
- Water reuse
- Limited space available
Biosep™ achieves high-performance treatment of industrial effluents for the following markets:
- Food and beverage
- Pharmaceuticals
- Cosmetics
- Chemicals
- Petrochemicals
- Biofuels
- Landfill leachate
- Pulp and paper
- Automotive
- Textiles…
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
