DRAW SOLUTION FOR FORWARD OSMOSIS

摘要

PURPOSE: Forward osmosis inducing liquid is provided to reduce the content of ionic inducing solute by inducing forward osmosis and implementing a heating process to easily separate the inducing solute from an aqueous solution. CONSTITUTION: Forward osmosis inducing liquid is an aqueous solution containing negative ions and positive ions as an inducing solute. A compound in a salt shape is dissolved in the aqueous solution and is dissociated into acidic negative ions and basic positive ions. The inducing solute is vaporized at temperature between 40 and 90 degrees Celsius and is separated from the aqueous solution. The vaporized inducing solute is cooled to be concentrated. The concentrated inducing solute is reused.
