Reclaiming process water at hazardous waste centre
Waste Treatment Centre, Alberta, Jan. 2016
BI Pure Water has designed and built an ultrafiltration/RO system for treating wastewater flows of 397 L/min (105 USGPM) and reclaiming up to 132 L/min water for the centre’s waste treatment process. The system enables the site to dispose of less waste and recycle water. An energy recovery device on the waste stream powers the RO pump, saving 30 to 40 percent in power costs.
The Waste Treatment Centre is located NW of Edmonton, and owned by the Alberta government. BI Pure Water was chosen to supply the system based on demonstrated expertise in waste system assessment and design.
Challenges to the process design included the varying inlet TDS levels and wastewater quality, plus the relatively high temperature of the wastewater. However commissioning of the system went very smoothly as it was design, build, and flow tested on a skid at BI Pure Water’s factory. It was shipped to site where it was reassembled and commissioned inside an existing building.
Al Wakelin, a contractor for the waste services management, says, “Let me say we are very happy with the way the system has operated to date and our operating staff are impressed with the control system and how the unit starts up. The system has been operated at design throughput with no hydraulic issues. The inlet wastewater TDS is less than design right now and, as expected, recovery percent is somewhat above design. I have enjoyed working with (BI Pure Water staff) and the field staff and from our side, budget and schedule constraints have been satisfied.”
Emergency water source for University of British Columbia
Vancouver, BC, April 2016
The University of BC contracted BI Pure Water to build an emergency water treatment trailer in order to have a standby source of water in the event of storm or earthquake. UBC currently gets its water from Metro Vancouver mountain reservoirs, a considerable delivery distance. UBC can now get water from a nearby rainwater supply, not connected to any fish bearing stream or ocean, and treat it for potable use. When the system is not needed it will be supplying irrigation water without disinfection to UBC Botanical Garden, thus saving $50,000 a year in water fees. The system will soon pay for itself.
