Notice of participation in "VIETWATER 2025" from Wednesday, October 22, 2025, to Friday, October 24, 2025. {Case studies are also being introduced!!}

The flow path is close to straight, with a structure that has low pressure loss and minimal liquid accumulation! It is suitable for fluids containing sludge, suspended solids, and more!

A diaphragm valve is a type of valve that has a structure that opens and closes the flow path using a flexible diaphragm (membrane) made of materials such as rubber. The "Straight Type Diaphragm Valve: 500 Series" features a flow path that is nearly linear (straight), resulting in a structure with minimal pressure loss and liquid accumulation. It is suitable for fluids containing viscous fluids, fibrous fluids, slurries, sludge, and suspended solids. ▼ Application Fields: Water treatment plants, final treatment facilities, etc. *For more details, please refer to the PDF materials or feel free to contact us.

The measurement technology for viruses in water has made remarkable progress since the introduction of PCR methods in the 1990s, with ongoing technical improvements aimed at ensuring quantitativeness. It is now possible to measure wild viruses in actual treatment facilities, allowing for the actual measurement of virus removal capabilities, which significantly contributes to ensuring water safety. Professor Hiroyuki Katayama from the University of Tokyo will provide a clear explanation of the utilization of these technologies, incorporating specific treatment case studies. Additionally, advancements in digital technology have enabled efficient and advanced water quality management in the fields of water supply and wastewater treatment, attracting attention for future developments. We will share practical insights gained from the field regarding the latest water treatment technologies utilizing AI and the use of online water quality meters.

From October 1st for three days, Oji Futech will be exhibiting at "Agriculture WEEK (commonly known as J-AGRI Tokyo Exhibition)" held at Makuhari Messe. Agriculture WEEK is an exhibition where agricultural materials, smart agriculture products, livestock materials, and more are showcased, facilitating active business discussions between exhibiting companies and visitors. At Oji Futech's booth within the Agricultural Materials EXPO, we will introduce our paper-based agricultural mulching sheet, "OJI Sustainable Mulch." Oji Futech's "OJI Sustainable Mulch" is a mulching sheet made primarily from cellulose. After use, it decomposes in the soil, which not only reduces waste disposal costs but also helps suppress soil temperature rise, leading to increased yields for summer and autumn crops. We will also be showcasing our freshness-preserving and antibacterial OPP film, "Calfresh," at the same booth. We look forward to your visit!
