Veolia has won a contract from Qatar Engineering & Construction Company to engineer, procure and deliver a wastewater treatment plant for Dolphin Energy's natural gas production and processing facilities in Ras Laffan, Qatar.

The wastewater treatment facility will facilitate water reuse thereby minimizing volume of wastewater being pumped into the existing re-injection wells at the Ras Laffan gas plant, and also reduce the volume of desalinated water purchased from external sources.

Qatar water industry regulators have concluded that the presence of KHI polymers in injected wastewater results in reservoir damage in the long run, which gives rise to the need to remove them from re-injected wastewater streams.

In 2015, Veolia had bagged a contract for its HPD evaporators which will be used for KHI removal and distillate recovery.

Under the new contract, Veolia will also provide a pretreatment package upstream of the evaporators using its MPP Tilted Plate Flotation technology.

Veolia Water Technologies Middle East COO Thierry Froment said: "Veolia has a rich history in Qatar supported by the development of a number of important projects, including one of the main treatment plants in Doha. We look forward to working again with Qatar Engineering & Construction Company to deliver this project for Dolphin Energy."

Ras Laffan is an industrial town about 80 km from Doha, which specializes in the production of liquefied natural gas.

The Dolphin Energy project is considered as one of the largest cross-border energy projects taken up in the Middle East. The project aims to provide natural gas from Qatar through pipeline to meet the UAE’s energy demands.
