Qatargas has completed the construction of a wastewater treatment plant at one of its LNG plants using the membrane bio-reactor (MBR) technology
The design, procurement and construction works of the project were led by a multi-disciplinary team at Qatargas including members of the environmental affairs, engineering and ventures departments that was set up in 2008, reported Qatar News Agency.
The facility, which has a capacity to treat 1,300 cu/m of wastewater per day, is a first for the LNG industry in the region, it stated.
The project was designed in response to an internally identified gap in the Qatargas 1 (QG1) process wastewater treatment facility in order to treat wastewater and get irrigation grade water that could be reused.
The pilot MBR plant was first tested for six months in 2008, following which QG1 embarked on the front end engineering design (FEED) and the execution phase contracts and the start-up between 2011 and 2015 for installation of a full scale MBR at the facility.
“The project is a very important accomplishment for Qatargas which has set a precedent in the LNG industry in the region to reuse wastewater at the QG1 plant,” said Sheikh Khalid bin Abdullah Al Thani, CEO of engineering and ventures department.
“This project is a clear manifestation of our commitment to environmental conservation and is part of the huge investments we have made in the recent past to minimise our environmental footprint, in line with the values spelled out in the Qatargas Direction Statement,” Al Thani added.
Qatargas is keen to introduce similar innovative solutions for wastewater treatment at its facilities in future, he revealed.
