After a major refurbishment, a Canadian nuclear plant required additional process and boiler feed water for
plant start-up and commissioning.
The plant’s raw water supply contained measurements ranging from 1-10 NTU, conductivity from 70-100 and
color units ranging from 180-420. The plant also experienced highly variable flow rates, ranging from 0-600
GPM, and issues with the performance of rental equipment in temperatures of -30 degrees Celsius.
MPW provided the nuclear plant with mobile ultrafiltration and demineralization units in order to fix the plant’s
raw water issues andprovide ultra-pure process and boiler feed water. MPW also heat traced and insulated all
outside lines in order to beat the extreme weather conditions.
The ultrafiltration unit operated for approximately one year,
reducing turbidity to less than 0.3 NTU and color units
ranging from 1-3. The unit’s chemtrac streaming monitor
allowed for 24-hour chemical adjustments both onsite and
remotely. The mobile demineralization trailers produced
approximately 2.5 million gallons per trailer and kept
conductivity measurements below customer specifications.
Even with multiple challenges and extreme winter
weather, MPW provided the process and boiler
