The two companies have signed a strategic cooperation agreement (SCA) to further technology development and implementation of water, wastewater and waste programs at Rosneft refinery and petrochemical sites.

Suez will offer technologies and solutions with pilot testing as per the needs. Areas under focus include wastewater pre-treatment, biological wastewater treatment, desalination for reuse, water purification by evaporation and various treatment programs for cooling water systems.

The company will also expand its existing technical advisory services, which are deployed at one of Rosneft’s sites, to other Rosneft’s sites.

This agreement as per Suez, further expands the cooperation between the two companies which first began more than a decade ago. Since that time Suez supplied its Membrane bioreactor MBR technology and cooling water treatment services to multiple Rosneft refineries.

Rosneft vice president Andrey Shishkin said: “Effectiveness and environmental safety of the oil and gas production is only possible if the latest technologies are used. Rosneft highly prioritizes innovative development in its operations and actively uses the latest digital technologies in all areas of the company’s activities.

“We are pleased that the experience and competencies of SUEZ, the leading company in the field of environmental technology development, are being used at Rosneft’s facilities.”

In January this year, Rosneft and Suez started a biological wastewater treatment plant at Rosneft’s Bashneft-Ufaneftekhim facility. This facility will treat up to 84,000m3 of wastewater per day using SUEZ industrial wastewater treatment technology. Equipment at the facility was supplied by Suez, as part of a 15 year agreement.

Suez CEO Jean-Louis Chaussade said: “Long-term partnerships, like the one between SUEZ and Rosneft, really show how two organizations can come together to drive forward technology and service programs that both support environmental sustainability and business initiatives.”

A few days back Suez through its joint venture Changshu Sino French Water, had won a €436m contract in China to own and operate four wastewater treatment plants for a period of 30 years. The contract was awarded by Changshu Water Bureau.
