Qatargas completes wastewater treatment plant at QG 1

Qatargas, the world’s largest LNG producer said on Tuesday it has completed works on a wastewater treatment plant for one of its LNG facilities using membrane bio-reactor technology.

The wastewater treatment facility with a capacity to treat nearly 1300 cubic meters of waste water per day has been set up at Qatargas 1, the company said in a statement.

The Qatargas 1 facility consists of three LNG trains with a total combined capacity of 10 million tons per annum. Shareholders in the project are Qatar Petroleum (65 percent), ExxonMobil (10 percent), Total (10 percent), Mitsui (7.5 percent) and Marubeni (7.5 percent).

Qatargas added that the wastewater treatment facility has been set up to cover “an internally identified gap in the QG1 process wastewater treatment facility in order to treat waste water and get irrigation grade water that could be reused.”

The pilot facility was first tested for six months in 2008. Currently, it operates at design efficiencies obtaining removal rates of more than 95 percent for key parameters including Chemical Oxygen Demand (COD) and Nitrogen compounds, Qatargas said.
