Notice of Participation in the 'Sustainable Plant EXPO 2024' from July 24 (Wednesday) to July 26 (Friday), 2024

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 facilities, 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 ■ Easy filter paper replacement with a simple mechanism ■ Compact and simple structure for easy maintenance *For more details, please refer to the PDF document or feel free to contact us.

SS capture volume has significantly increased! Achieving a reduction in operating costs. Remote monitoring is also possible with the introduction of IoT!

Introducing the "Microbubble Precoat Filtration System" from Sanjin Manufacturing. By forming a precoat layer that stably mixes and supplies filtration aids and microbubbles on the filter media, we have enabled long hours of filtration operation while maintaining high filtration precision. The increase in the amount collected per precoat cycle extends the backwashing frequency, reduces the amount of filtration aids used, and decreases waste generation. Furthermore, by utilizing an IoT remote monitoring system, we can monitor and confirm abnormalities occurring in the equipment on-site. Additionally, by saving and graphing measurement data for pressure, flow rate, temperature, and current, we can analyze the operating conditions. [Applications] Chemical agents / Various plating / Liquid coolant / Pools / Related hot spring facilities, etc. [Features of the Filtration System Using Microbubbles] ■ Significant increase in SS (suspended solids) collection ■ Reduction of the working time required for precoat operation ■ Maintenance of filtration precision comparable to conventional methods ■ Reduction in the amount of filtration aids used and waste generation

On that day, we will provide detailed explanations of the following disaster prevention products using models, panels, and various materials. ◆Exhibited Products◆ - Pile-type debris flow and driftwood countermeasures for non-flowing streams / Urban Guard (model display) Additionally, our representative will conduct a technical presentation, so we kindly invite you to attend.

Protech Engineering (Booth Number: 240) will be exhibiting at the "Hokkaido Construction Development Comprehensive Exhibition 2025," scheduled to be held on October 8 (Wednesday) and 9 (Thursday), 2025. On the day of the event, we will provide detailed explanations of the following disaster prevention products using models, panels, and various materials. ◆ Main Exhibited Products ◆ - Energy-absorbing rockfall protection fence / ARC Fence (model display) - Landslide debris protection fence / Slope Guard Fence Type LE (model display) - Pile-type (pile foundation) debris flow and driftwood countermeasure for non-flowing streams / Urban Guard - Avalanche prevention piles / Tri-Pile - Avalanche protection fence / Slope Guard Fence Type LS - High energy-absorbing rockfall protection fence / Macro Fence In addition, we will have a variety of materials on disaster prevention products developed independently by Protech Engineering, so we kindly invite you to visit our booth.

Profect Co., Ltd. will hold a seminar on October 3rd (Friday) themed around the IT Implementation Subsidy 2025 and our developed and sold production management system "TED." This year's IT Implementation Subsidy has seen a significant decrease in the acceptance rate compared to previous years. Many companies are struggling with the situation of having wanted to implement IT tools but being rejected. In this seminar, we will explain why the acceptance rate has dropped, the background behind it, and the key points for being accepted. Additionally, we will introduce our initiatives that have achieved a 100% acceptance rate so far this year and the reasons why our production management system "TED," registered as an IT tool, is chosen. To accommodate busy schedules, this seminar will be held in a hybrid format, allowing for both in-person attendance and online participation via Zoom. Please choose your preferred method of participation according to your convenience. If you are currently considering applying for the IT Implementation Subsidy or are interested in production management, we encourage you to join us. We sincerely look forward to your application.

An international forum aimed at promoting the circular economy and closed-loop economy, "Closed Loop Recycle Forum 2025 (hereinafter referred to as CLRF2025)," will be held for two days from November 25 (Tuesday) to 26 (Wednesday) at The Oriental Terrace in Chuo Ward, Hamamatsu City, Shizuoka Prefecture. In Europe, closed-loop recycling practices are already advancing. We have organized this international forum as a platform to connect the forefront of Europe with Japan's challenges, striving for a future that balances economic viability and environmental sustainability. A total of 12 speakers, including Chairman Kajiwara of the Waste and 3R Research Foundation and Director Kaneko of the Ministry of the Environment's Container and Packaging Recycling Division, along with leading recycling operators and researchers from Japan and Europe, will present advanced examples of the circular economy and closed-loop economy. Furthermore, through discussions on the feasibility and challenges of implementation in Japan, we will explore hints for sustainable business models that companies and local governments should aim for.
