三進製作所 List of Products and Services

This is a series of equipment and devices for pure water production under the recycling synonym "EconoBack System," which compactly integrates the durable "RO membrane" and "mixed-bed ion exchange tower." By using our unique "Resource Recovery Center System" for the regeneration of the mixed-bed ion exchange tower, it eliminates the need for any waste liquid treatment at the installation site. ● All the functions necessary for water production are condensed into this one unit. ● The compact unit design saves installation space and offers an affordable price. ● The regeneration of the mixed-bed ion exchange tower can utilize the collection and regeneration service provided by our unique "Resource Recovery Center System," eliminating the need for "waste liquid treatment at the installation site" and "costs associated with ancillary installations."

A large filtration machine specifically designed for alkaline zinc plating baths that allows for in-situ cleaning without removing the filter material, achieving high filtration precision and excellent operational usability at a lower cost!! * As a pre-coat filtration machine, the filtration precision is outstanding. * Used as a precision filtration machine for plating baths of approximately 4,000 to 8,000 liters. ● The plating solution inside the filtration machine is collected before cleaning, so there is almost no loss of plating solution due to cleaning (only for water-washing type). ● We offer three types of filter cloth cleaning methods to further enhance usability. ● F55A-H type: Automatic filter cloth cleaning type The most affordable standard model. Filter cloth cleaning is done automatically using water. ● F55A-A1 type: Fully automatic water-washing type Automatically operates the valves for pre-coating, filtration, and filter cloth cleaning. Filter cloth cleaning is done automatically using water. ● F55A-A2 type: Fully automatic co-liquid washing type Automatically operates the valves for pre-coating, filtration, and filter cloth cleaning. Since the filter cloth cleaning is done with co-liquid, no cleaning water is discharged, and the filtered SS can be removed as a dewatered cake along with the filtration aid.
