Membrane Bioreactors

An effective process for treatment and reuse of industrial and municipal wastewater, Membrane Bioreactors, or MBR, combines a membrane separation process such as microfiltration, ultrafiltration or reverse osmosis with a suspended growth bioreactor.

Veolia Water Technologies has been researching MBR since 1991 and has gained a high level of expertise. This led to the development of Biosep™, an innovative aerobic biological treatment process treating municipal and industrial effluents and Memthane®, an anaerobic Membrane Bioreactor (AnMBR), which treats high-strength streams previously considered economically untreatable through traditional wastewater processes alone. Treatment is for industries like distilleries, dairies, bio-ethanol and instant coffee plants.

Veolia's membrane bioreactors include:

  • Biosep™
  • Memthane®


Biosep™ is an aerobic biological treatment process treating municipal and industrial effluents.

The solution 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

Memthane® is an anaerobic membrane bio-reactor (AnMBR) that maximises renewable energy production while producing superb quality effluent that can be reused or discharged directly to a sewer system. The new leading-edge technology, developed by Veolia Water Technologies' subsidiary Biothane, delivers a unique, small footprint solution that offers an array of benefits, reducing disposal costs while generating valuable biogas.

Memthane® opens the door to treatment of high-strength and high-solid streams found in industries like distilleries, dairies, bio-ethanol producers, instant coffee plants, etc. The suspended free effluent also facilitates easy recovery of nutrients for fertiliser production and water recycling to the plant.

The valuable methane-rich biogas produced can cover a significant part of the production plant's energy and heat demand, which can be as high as 100% in distilleries, for example. Due to the favourable investment and operating with robustness, clients are increasingly choosing Memthane® as their preferred wastewater treatment solution.
