A refinery under construction in Saskatchewan will clean 100 percent of its wastewater on-site using water-recycling technology from GE, Trevose, Pa.

Once the water-recycling system is fully operational in the fall, Federated Co-Operatives Ltd.'s  Co-op Refinery Complex in Regina will recycle its wastewater for steam production used for heating and hydrogen production, to power equipment and for cooling towers. According to GE, the facility will be the only refinery in North America to recycle 100 percent of its wastewater.

The refinery expanded its operations several years ago to produce 30,000 more barrels of oil per day (BPD) – making it a 130,000-BPD facility – which increased its water usage. Before adding the water-recycling technology, the refinery used a blend of well water and city water, but restrictions on water use mandated that the complex find a new water source.

GE’s solution combined membrane bioreactor technology and a high efficiency reverse osmosis system to recycle and reuse 2 million gallons of wastewater a day. GE also will provide wastewater specialty chemicals and monitoring solutions to provide system optimization.

After commissioning, the refinery will reduce its use of fresh water by 28 percent, which is the equivalent of approximately 3,100 households in Regina, on an annual basis.
