Canadian low-energy desalination gets government boost
Saltworks Techologies Inc's low-energy desalination project is to receive up to Can$ 580,000 (US$ 577,000) from the Canadian government via Sustainable Development Technology Canada (SDTC).
The low-energy desalination demonstration project involves building and testing a commercial-scale 1,000 L/d pilot plant for seawater and brackish industrial water treatment. This system is powered by an inexpensive low-temperature thermal-energy conversion system that can use solar energy or process heat to reduce electricity consumption.
The system is expected to operate without chemicals, while avoiding the harmful salt loading that is often associated with other desalination approaches. The process also has the capability to input waste saltwater brine and treat it to produce freshwater and solid salt with low energy consumption.
Other project partners include BC Hydro's Powertech Labs Inc and the BC Innovative Clean Energy Fund.
