Abstract
A method of making building materials from an aqueous solution includes receiving the aqueous solution with dissolved ions and increasing a pH of the aqueous solution so the dissolved ions precipitate from the aqueous solution as salt. The method also includes collecting the salt precipitated from the aqueous solution and forming the building materials from the salt.
Claims15
A method of making building materials from an aqueous solution, comprising:
- receiving the aqueous solution including dissolved ions with a first precipitation unit;
- increasing a pH of the aqueous solution in the first precipitation unit with aqueous NaOH received from an electrodialysis unit, coupled to the first precipitation unit to precipitate the dissolved ions from the aqueous solution as salt;
- collecting the salt precipitated from the aqueous solution;
- and
- forming the building materials from the salt.
