Separating metal salts and free acids using only water! Video available!
The recirculator is a device that separates metal salts and free acids from a metal-containing acidic solution using a special ion exchange resin, discharging the metal salts. The recovery of free acids requires no energy such as chemicals or heat; it only uses water, making it very economical. It maintains a constant composition and concentration of processing solutions, such as etching. * Automation of acid solution concentration management. * Stabilization of the acid treatment process. * Extension of the lifespan of acid solutions. * Reduction of acid consumption. * Reduction of waste acid disposal costs. * Mitigation of the burden on wastewater treatment. * Reduction of nitrogen concentration in discharged water through nitric acid recovery. ● Efficiently separates metal salts and free acids in acidic solutions. ● Only water is needed for the recovery of free acids; regeneration with chemicals is unnecessary. ● The composition of acid treatment solutions, such as for etching, stabilizes, extending the lifespan of the processing solution.
