Title:
RECYCLING WASHING SOLUTIONS
Document Type and Number:
WIPO Patent Application WO/2020/258235
Kind Code:
A1
Abstract:
A method for separating solid waste from a washing solution includes collecting the washing solution from an industrial process and separating the solid waste from the washing solution using a centrifuge. The washing solution includes hydroxide and other washing additives. A system for recycling washing solutions includes a tank (102) for the washing solution in fluid communication with a centrifuge (106). The centrifuge removes solid waste and returns the washing solution to the tank. Hydroxide and other washing additives in solution can be reused more times when there is less solid waste suspended in the solution.
