The Bashneft-Ufaneftekhim refinery in the Russian city of Ufa has inaugurated a biological treatment plant which is claimed to be the world's largest industrial facility using membrane bioreactor (MBR) and electrodialysis reversal (EDR) technologies. The facilities 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 Bashneft-Ufaneftekhim biological treatment plant and will provide services as part of a 15-year contract to ensure reliable operation of equipment.

Suez reports its MBR technology significantly improves treatment efficiency by passing water through microscopic pores of membranes, removing impurities and microorganisms. Further treatment is performed with SUEZ EDR, RO and ion exchange technologies to ensure treated wastewater compliance with the toughest discharge and reuse regulations.

As part of the long-term service contract for the plant, Suez is providing advanced asset performance management with its InSight platform. InSight combines data and analytics to maximize performance, minimize unplanned downtime, lower operating costs and deliver better business outcomes.

"I believe that commissioning of a modern biological treatment plant – a large-scale environmental protection facility using the world best technologies for water treatment – will be a significant event not only for the company and the Republic of Bashkortostan, but for the whole country,” says Igor Sechin, chief executive officer of Russian petroleum giant PJSC Rosneft.
