Qatargas has completed construction of a wastewater treatment plant at one of its Liquefied Natural Gas (LNG) plants using Membrane Bio-Reactor (MBR) Technology.
The facility, set up at the Qatargas 1 (QG 1) plant with a capacity to treat nearly 1,300 cubic meters of waste water per day, is a first for the LNG industry in the region.
Kentz Corporation won a $125mn contract in June 2014 to supply a new wastewater facility to Qatargas at its LNG plant at Ras Laffan Industrial City.
The scope of work included Engineering, Procurement, Installation, Construction, and Commissioning (EPICC) services to deliver wastewater recycling and reduction facilities to four LNG trains.
The project was designed in response to 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 in line with the State of Qatar’s Ministry of Municipality and Environment (MoME) regulations.
This facility uses a Membrane Bio-Reactor which uses a combination of bacterial bio-reactor to consume and breakdown the pollutants. The downstream of this bio-reactor’s man-made membranes are used to screen out larger particles, bacterial-biomass and other compounds.
Qatargas is keen to introduce similar innovative solutions for wastewater treatment at its facilities in future.
