Canadian oil refinery to re-use 100% of water with GE’s wastewater treatment technology

Federated Co-Operatives Ltd.’s refinery complex in Regina, Saskatchewan, Canada, is installing General Electric’s advanced water recycling technology for a wastewater improvement project that will enable the refinery to clean 100% of its wastewater on-site. Once fully operationally, the Co-op Refinery Complex will be the only refinery in North America to recycle all of its wastewater for steam production, which is used for heating, hydrogen production, to power equipment and for cooling towers.

Several years ago, the refinery expanded its operations to produce 30 Mbpd more, taking it from 100 Mbpd to a 130 Mbpd facility, which increased its water usage. The refinery’s current water source is a blend of well water and city water, and restrictions on water use mandated that the Co-op Refinery Complex had to find a new source of water. GE offered a solution combining membrane bioreactor technology and a high-efficiency reverse osmosis system to recycle and reuse 2 M gallons of wastewater a day. In addition to the water reuse solution, GE provides the refinery with wastewater specialty chemicals and monitoring solutions to provide system optimization.

After commissioning, the refinery will reduce its use of freshwater by 28%, which is the equivalent of approximately 3,100 households in Regina, on an annual basis. By recycling 100% of its wastewater on-site, the Co-op Refinery Complex will significantly decrease volatile organic compound emissions from its wastewater ponds and reduce the associated nuisance odors. The wastewater improvement project is expected to be fully operational by the fall of 2016.
