Industries

Back to sectors
Industries now need to rise to a combination of major environmental, regulatory, social, economic and operational challenges. As a result, they have begun to look beyond simple service solutions in search of a truly creative partner able to innovate. This is the kind of ongoing challenge at which Veolia excels.

The equivalent of 80 Olympic-sized swimming pools treated every day


Veolia manages and ensures the maintenance of three water treatment plants which treat water involved in the production of coal gas.

QGC


A COMPLEX PROCESS FOR TREATING PRODUCTION WATER

QGC, a wholly-owned subsidiary of BG Group, one of the world's leading oil and gas companies, has awarded Veolia a 20-year contract to manage its three coal gas water treatment facilities in Queensland, eastern Australia. The facilities are on the sites of QGC in Kenya, Wolebee Creek and Windibri.  Veolia was chosen for its unique expertise in managing the complete production water treatment cycle in the complex field of unconventional oil and gas. The company’s strong local presence was a decisive selling point.

 
WATER FOR INDUSTRY AND AGRICULTURE

The gas field operated by QGC spans 4,500 square kilometers. Plans call for drilling 6,000 wells by 2030 and Veolia will treat the production water of each new well brought on stream. In all, close to 200,000 cubic meters will be treated per day – the volume of 80 Olympic swimming pools -  and a very high-quality end product will be guaranteed on a long-term basis. The production water – which is pumped up from the wells at the same time as the methane – has high salt content and must undergo complex treatment before it can be reused in industry or agriculture.


97% OF THE TREATED WATER WILL BE REUSED

The water storage and transfer system consists of a number of aggregation ponds that allow blending of the associated water from the wells. This produces a consistent water quality.
The water treatment systems are a robust series of mainly physical processes that progressively clean the water to a pure, safe and consistent standard. The efficient reverse osmosis treatment process will convert almost 97% of produced water into treated water suitable for beneficial use.
