The Eco Ace type filtration system and its main components have been standardized, and the functionality of the cylinder-type ion exchange machine has been miniaturized without alteration. ● Just like the filtration system, handling and maintenance management are extremely simple. ● There are two types of cartridge-type ion exchange towers: 0.5L and 5L, which can be selected according to the capacity of the washing tank. ● By connecting the Eco Ace housing in series and simply setting the ion exchange tower, water circulation and metal recovery can be initiated immediately. ● As a pretreatment, if the removal of organic matter is necessary, the molded activated carbon Loca-Carbo series can be used. ● The used saturated ion exchange towers of the 5L type are regenerated at our Inuyama factory's resource recovery center and delivered back to various plating factories.

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.
