Notice of Participation in "SURTECH2026 Surface Technology Elements Exhibition"

Visualization through conventional water quality monitoring and newly developed coagulation sensors.

By utilizing an IoT monitoring system for filtration machines and wastewater treatment equipment from Sanjin Manufacturing, it is possible to monitor and confirm abnormalities occurring in the equipment on-site. Additionally, the operating status can be analyzed from the measurement data of various sensors. 【Solution Overview】 ■ IoT Remote Monitoring System - Remote monitoring and confirmation of equipment abnormalities - Saving and graphing measurement values from pressure gauges, flow meters, ammeters, conductivity meters, liquid level meters, pH meters, ORP meters, etc., to analyze operating conditions ■ Coagulation Sensor (Newly Developed) - Real-time remote monitoring of the "coagulation state" of the coagulation separation equipment - Visualization of floc formation to understand fluctuations in raw water conditions and optimize chemical dosing 【Features】 ■ Labor-saving: Reduces the burden of on-site inspections, eliminating the need for visual confirmation ■ Stabilization: Stabilizes treated water quality through chemical control according to water quality fluctuations ■ Safety and Security: Early detection of abnormal coagulation and sedimentation issues to reduce environmental risks ■ Performance Improvement: Enhances the quality of coagulation treatment and optimizes sludge generation ■ Quality Improvement: Guarantees stable treatment quality even for difficult-to-treat wastewater *We will build a system tailored to your application. Please feel free to contact us for more details.

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.
