Adopting FRP towers, achieving high corrosion resistance, lightweight, and low cost! We provide high-quality ion exchange resin through our route at a low price! No regeneration costs, designed for resin replacement by customers only! By eliminating regeneration costs at the manufacturer, we remove the time lag in water sampling due to regeneration and the need for a standby tower, reducing running costs with low-cost, high-quality resin. Please give it a try!

From October 18 (Wednesday) to October 20 (Friday), we, the Kotobuki Group, will be exhibiting at the "Lake Biwa Environmental Business Messe 2017" held at the Nagahama Bio University Dome in Shiga Prefecture! The theme of our exhibition is a proposal for wastewater reuse using "UV-AOP (Ultraviolet Advanced Oxidation Process)" and an introduction to our "ion exchange resin." We have expressed the UV-AOP and wastewater reuse model inspired by Lake Biwa in a diorama! Additionally, our technical department will present on the "wastewater reuse system incorporating UV-AOP" (on October 18 at 14:45 for 25 minutes in Presentation Room 1). We also welcome any inquiries you may have regarding water-related issues. We look forward to seeing you there!

We can provide "coarse dust filters," "medium to high performance filters," "filters for packaged air conditioners," and "HEPA filters" for indoor units, air handling units, heat exchangers, and other air conditioning equipment. Please let us know the manufacturer's name and model of the equipment. A sales representative will contact you!

With the advancement of medical devices, various types of special wastewater are discharged from medical facilities. As a specialized manufacturer of water treatment and wastewater treatment, our company has delivered numerous wastewater treatment systems tailored to the diverse applications of hospitals, research institutes, clinical testing centers, and other sectors across the country, thanks to our high level of expertise.

Started selling ultraviolet sterilization devices. We have also begun selling a low-cost, low-running-cost 300W model in addition to the conventional 100W ultraviolet device. This will contribute to reducing the running costs of existing ultraviolet devices. Additionally, we handle ultraviolet sterilization devices for air, which are effective for sterilization and deodorization indoors.

We have started handling ion exchange resins for the recovery of rare metals such as palladium, platinum, gold, and silver contained in various solutions. If you contact us with the type of solution and the materials to be recovered, we will select and propose the most suitable ion exchange resin.

We are pleased to announce that our company has obtained a patent for a method of decomposing organic substances containing refractory organic matter through a combination of biological treatment, AOP (Advanced Oxidation Process), and activated carbon. (Patent No. 5701648) By combining ultraviolet light and oxidants, we generate OH radicals with strong oxidative properties, utilizing their ability to break molecular bonds in the AOP process. The device incorporating our AOP differs from conventional methods by establishing a circulation line in the treatment line, effectively decomposing refractory substances through a combination of chemical and biological oxidation. Additionally, it significantly extends the lifespan of activated carbon by promoting its self-regeneration function. If your company is facing challenges in the biological treatment process or the treatment of refractory organic matter, please feel free to consult with us.

For 60 years, we have been dedicated to water treatment and providing products to purify water. We are pleased to announce that our company has now started handling air filters for air conditioning equipment. If you are considering cost reduction for filters in commercial air conditioning units, please feel free to contact "Juhwa Koki." We can accommodate "coarse dust filters," "medium to high-performance filters," "package air conditioner filters," and "HEPA filters" for indoor units, air handling units, heat exchangers, and other air conditioning equipment. Please provide the manufacturer name and model number of the equipment. Our sales representative will get in touch with you!

We have added a high corrosion-resistant FRP type of flock separator (high-speed sedimentation tank) to our lineup!! For more details, please contact us.

The AOP (Advanced Oxidation Process) lamp unit has started production in-house! For more details, please contact our company.
