The addition of salts to water is a common step within many industrial chemical processes. For example, adding salts to water (i.e. increasing the ionic strength of an aqueous solution) enables the isolation of chemical products from water solutions. The problem with this is that once the process is complete, a quantity of salty water remains, which cannot be reintroduced back into the environment and therefore must be remediated through costly and energy intensive procedures.
Enter the Switchable Water technology, part of the Switchable platform invented at Queen's University by Dr. Philip Jessop and in-licensed by GreenCentre. The Switchable Water system offers an easy and energy efficient way to "add and remove" salts from water solutions. Ultimately, once the process no longer requires the water, it can be re-introduced into the environment in its benign, salt-free, form.
