Acid-Metal Salt Separation Device "Resiter"
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; only water is used, 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. No chemical regeneration is required. ● The composition of acid treatment solutions, such as for etching, is stabilized, extending the lifespan of the processing solutions.

Notice of Participation in "SURTECH2026 Surface Technology Elements Exhibition"
Sansin Manufacturing Co., Ltd. will be exhibiting at the "SURTECH 2026 Surface Technology Elements Exhibition" held at Tokyo Big Sight. At our booth, we will showcase the "Filtration and Wastewater Treatment Equipment Utilizing IoT" and the "Acid and Metal Salt Separation Device, Resiter." The "Filtration and Wastewater Treatment Equipment Utilizing IoT" continuously monitors water quality and operating conditions using IoT and sensors, achieving labor-saving for on-site inspections and automation of chemical control. It supports the stabilization of wastewater treatment, safe operation of chemical equipment, and rapid response during troubles. The "Acid and Metal Salt Separation Device, Resiter" separates and discharges metal salts from acid solutions containing metal salts using special ion exchange resins and the power of water, economically recovering free acids. Since it does not require chemicals or thermal energy, it contributes to cost reduction. We sincerely look forward to your visit. *This exhibition requires complete pre-registration. Please register using the "Details & Application" button below. Date: January 28 (Wednesday) to 30 (Friday), 2026, 10:00 AM to 5:00 PM Location: Tokyo Big Sight, South Hall 4 Booth Number: 3S-U22, 4S-N02
