Efficiently demonstrating two functions of filtration and dehydration in a small-scale, continuous production line!

Introducing the small PF automatic dewatering filtration machine "Represstar" from Sanshin Seisakusho. This machine is an automatic dewatering filtration system that performs filtration, liquid removal, and cake discharge for high-concentration slurries. It operates efficiently in small-scale, continuous production lines. Various non-woven fabrics (filter papers) are used as filter media, and depending on the liquid used, they can be reused. Additionally, by combining it with the FD-type precision filtration machine, a filtration system can be established that accommodates large volumes and difficult-to-filter materials. Furthermore, by utilizing an IoT remote monitoring system for Sanshin Seisakusho's filtration machines and wastewater treatment equipment, abnormalities occurring in the equipment on-site can be monitored and confirmed. 【Applications】 Removal and recovery of sediment sludge generated in machine shops, painting factories, and forging factories / Recovery treatment of copper from the surface grinding process in electronics manufacturing plants / Other filtration, dewatering, and solidification treatments. 【Features of Represstar】 ■ Low-cost processing of large amounts of sludge generated in small-scale continuous production lines ■ No labor required during operation due to continuous automation mechanisms ■ Simple mechanism allows for easy replacement of filter paper ■ Compact and simple structure makes maintenance easy *For more details, please refer to the PDF document or feel free to contact us.

We will recycle water and metals through collection and retrieval!

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.

Recently, fine bubbles, which are tiny bubbles smaller than 100 μm and are referred to as "fine bubbles," have attracted attention in various fields such as the environment, agriculture, food, fisheries, and medicine, due to their ability to impart various functions to liquids. Fine bubbles are classified into two types based on their size: microbubbles and ultrafine bubbles. Recently, there has been a growing interest in ultrafine bubbles, which have a lifespan of several weeks to months. However, listening to the voices of researchers and users reveals some skepticism, which has become one of the issues hindering the spread of fine bubble technology. On the other hand, we have challenged the elucidation of the stabilization mechanism of ultrafine bubbles from a new perspective by enabling the control of number density exceeding 10 billion particles/mL without pressure or concentration operations using our ultrafine bubble generation technology. In this seminar, we will provide a fundamental explanation of fine bubble technology, including the basic physical properties, characteristics and functions, device technology, measurement and evaluation methods, and case studies, to promote research and utilization of fine bubbles based on a correct understanding.

Sekiguchi Iron Works Co., Ltd. will exhibit at the "Minami-Shinshu Environmental Messe 2025" held at S-Bird in Iida City, Nagano Prefecture.
