A Russian refinery is reportedly the world’s largest industrial facility using membrane bioreactor (MBR) and electrodialysis reversal (EDR) technologies. Bashneft-Ufaneftekhim’s biological treatment plant, located in Ufa, will treat up to 84 million liters of wastewater per day.

Suez supplied its ZeeWeed MBR membranes, EDR and reverse osmosis (RO) equipment to the facility and will provide services as part of a 15-year long-term service contract to ensure reliable operation of equipment and an uninterrupted guaranteed replacement of membranes. Suez MBR technology improves treatment efficiency by passing water through microscopic pores of membranes, removing impurities and microorganisms. Further treatment with EDR, RO and ion exchange technologies ensure treated wastewater compliance with discharge and reuse regulations and minimize the waste stream’s disposal.
