C-EDR demonstration hits 4,000 hours of run-time in Northern BC

Desalination trailer treats 40-million litres of water for less energy than it takes to run a refrigerator for a year.

Ionic Solutions’ desalination trailer recently returned from a 6-month project in the District of Taylor in Northern B.C. where it demonstrated sustainable, low-power, municipal water softening in one of Canada’s hardest water communities.

Key project outcomes include incredibly low power consumption, zero-scaling and retained mineral content of treated waters. The demonstration is further validation of the capabilities of Ionic Solutions’ patented C-EDR technology as the greenest, most sustainable, water desalination technology in the world.

Taylor’s hard water problem

In the District of Taylor, municipal groundwater wells are infiltrated by the adjacent Peace River. This phenomenon is common; most rivers, streams and lakes exchange water with surrounding groundwater aquifers. But the Peace River carries with it a high concentration of mineral deposits from rock pack, which increases the prevalent hardness and overall salinity of the region’s drinking water.

“The water in Taylor is cation rich with the corresponding anions being mostly bicarbonates, some sulfates, and very few chlorides,” explains Kevin Slough, water expert and Ionic Solutions’ VP of Projects. “High concentrations of calcium bicarbonate and magnesium bicarbonate can decompose when heated, at which point an insoluble carbonate, or carbonate scaling, is formed.”

Town officials expressed a desire to reduce the hardness, and consequent scaling, while retaining the taste and health benefits of their mineral-rich water. The aim of the demonstration was to reduce the hardness of Taylor’s water by 50% while leaving essential minerals, including calcium and magnesium, intact.

During the project, run-time data was collected and monitored at Ionic Solutions’ Calgary Headquarters where they were analyzed by Ionic’s Research Scientist, Dr. Nicholas Randell.

Key outcomes in water chemistry:

  • Water hardness (as a CaCO3) was reduced by 58%
  • Total Dissolved Solids were reduced by 55%
  • Canadian Drinking Water Quality hardness classification was reduced from ‘Very Hard’ to ‘Hard’

Key operational outcomes:

  • Freshwater recovery rate of 85%
  • Energy consumption of 9 kWh/day or 0.043 kWh/m3 of water processed
  • Operating cost of the trailer is less than $3 per day at full capacity

Where next for C-EDR?

Currently, our desalination trailer is being re-fitted for a project at a power station in Saskatoon, Saskatchewan where C-EDR technology will support the client in meeting goals for improving feed water quality for steam generation.

An additional demonstration trailer is under construction and will be used to treat irrigation water on a golf course in Alberta where road salt run-off has created overly saline pond water which is negatively affecting the health of its irrigated vegetation.

Other upcoming projects include recovery of reverse osmosis reject for reuse in New York City and treatment of brackish ground waters for light industrial applications in California.
