トーケミ List of Products and Services

Activfiber has the following features due to its very high void ratio and surface area. 【Features】 ● Reduction of installation space It can achieve filtration speeds approximately five times faster than granular filtration media, allowing for smaller filter tower sizes and a reduction in installation space. ● High turbidity capture capacity With a void ratio of over 90% (compared to around 50% for sand and anthracite) and the use of a large amount of fibers in the tens of micrometers, it has a large surface area, enabling a higher turbidity capture capacity compared to granular filtration media. ● Reduction of cleaning water volume A powerful simultaneous cleaning method using air and water is employed, allowing for significant cleaning effects with a small amount of cleaning water.

【Features】 High-purity water with turbidity below 0.1 degrees This unit efficiently performs membrane filtration and cleaning, fully demonstrating the performance of SuperMF.

This is a vessel-type SMF membrane capable of compact and large-capacity processing. 【Features】 1. Achieves high flux through special membrane manufacturing. 2. Excellent cleaning ability realized by the combined use of water and air. 3. Capable of removing Cryptosporidium and Legionella. Certified product according to the water supply membrane module standard AMST-001 (7th edition) (SMF-PVDF-V40).

This is a hollow fiber module that can be used not only as a immersion membrane for water purification during high turbidity but also as an MBR (Membrane Bioreactor) that is gaining attention for wastewater treatment. 【Features】 1. Compact installation size and space-saving 2. Capable of handling increased treated water volume 3. Stable treated water quality 4. Water recycling is possible 5. Supports concentration recovery in various scenarios

【Features】 ● By reducing ammonia nitrogen, which consumes a large amount of sodium hypochlorite, it is possible to suppress excessive chemical injection, thereby ultimately controlling the concentration of chlorate. ● Depending on the concentration of ammonia in the raw water, it is possible to combine filling materials and units, allowing for compatibility with high concentrations of ammonia.

【Features】 ● Coagulation Sedimentation Unit A water treatment method that flocculates suspended substances with a coagulant and separates them by sedimentation using gravity. Suitable for wastewater containing heavy metals and for post-treatment of biological processes! ● Pressurized Floatation Separation Unit A water treatment method that attaches air bubbles to relatively light suspended substances for flotation separation. Suitable for treating wastewater containing oil!

The importance of water is being emphasized not only in Japan but also around the world. Among this, the "RO system," which converts abundant seawater into drinking water, has been standardized as cutting-edge technology. Tokemi, a comprehensive manufacturer of water treatment equipment, has partnered with ProMinent, a major global water company that provides OEM RO systems, to offer everyone the "container storage type RO system," utilizing our accumulated systematization know-how.

We would like to introduce the products of Prominent, which we handle. Starting with the electromagnetic diaphragm metering pump "Gamma X" suitable for high-viscosity liquids, we also offer the water quality indicator and controller "Dalkometer D1C" equipped with alarm relays and measurement output functions, as well as the chlorine dioxide generator "Velozon Series." We provide total solutions for water treatment with a global service system and a diverse product lineup. 【Product Lineup (Excerpt)】 <Electromagnetic Diaphragm Metering Pumps> ■ Gamma X ■ Gamma XL ■ Beta ■ Extronic ■ Concept Plus *For more details, please refer to the PDF materials or feel free to contact us.

Since its establishment in 1965, Tohkemii has introduced products and technologies that you can use with confidence, based on the experience and achievements it has cultivated as a top manufacturer of filtration materials.

【Features】 ● With a filtration precision of 3 microns, it removes 99.9% of Cryptosporidium in addition to improving turbidity. ● Simple design: Extremely compact design makes securing installation space very easy. ● Not only for Cryptosporidium measures at water treatment plants, but also serves as an alternative to sand filtration for various applications, as well as for final effluent treatment before river discharge and pretreatment for UF/RO membranes, with numerous delivery records in the 2 to 10 micron filtration range.

Tokeimi Co., Ltd. will exhibit at the "2025 Hiroshima Water Supply Exhibition" to be held at Hiroshima Gate Park from October 29 (Wednesday) to 31 (Friday), 2025. New water quality risks are gaining attention due to frequent natural disasters across Japan causing high turbidity water, facility failures due to aging infrastructure, and contamination by Cryptosporidium. In response to these challenges, the "containerized water purification system" can respond quickly and flexibly. This system houses the main processing unit in a 20ft container, allowing for rapid transportation and installation to disaster-stricken areas or small communities by vehicle. It can resume water supply in a short time as long as a water source is secured, without relying on existing infrastructure. The treatment flow efficiently removes turbidity using the fiber filter "Activfiber," followed by sand filtration or hollow fiber membrane (SMF) to produce high-quality water, which can be used as utility water or for daily living. 【Features】 - Excellent mobility - Compatible with various water sources - Capable of large-volume water supply - Usable during normal times - Superior weather resistance and long-term storage capability
