三進製作所 List of Products and Services

With the "EconoBack System" for filtration, wastewater treatment, and resource recovery and reuse of water, chemicals, and metals, we achieve not only partial optimization but also overall optimization! This includes filtration, recovery of valuable metals, reduction of chemical usage and washing water volume, and removal and purification of impurities. Our goal is to provide a low-cost, environmentally friendly, zero-discharge treatment plating system focused on resource recovery and recycling. We propose optimal products for each process: "Degreasing → Acid Washing → Plating → Recovery → Washing → Resource Recovery." ● Products for degreasing... Oil-water separation device for degreasing baths ● Products for acid washing... Acid and metal salt separation device ● Products for plating... Filtration machines, concentration devices ● Products for recovery... Concentration devices ● Products for washing... Filtration machines, cylinder-type ion exchange devices ● Products for resource recovery... Resource recovery center system.

This is a recovery and regeneration system for a cylinder-type ion exchange tower that achieves water recovery and metal recovery in water washing processes. Saturated cylinder-type ion exchange towers are collected at our "Resource Center," and the regenerated cylinders are reused repeatedly by users. Components such as heavy metals adsorbed by the ion exchange resin are sorted and regenerated at the "Resource Center," and metals are sent to Yamamoto Refinery as valuable resources to be reused as raw materials for metals. With the equipment enhancement in April 2010, the "Resource Center" has become even more functional, concentrating and purifying chromic acid leachate to the recovery standard for re-resourcing using a chromic acid recovery device. Additionally, copper and nickel, which were traditionally turned into sludge and re-resourced at Yamamoto Refinery, are now recovered as metal foil using a roll-type electrolysis device, achieving improved resource recovery efficiency and reduced waste volume.
