Sterilization and organic matter decomposition device Steril Radical using ultraviolet lamps. Available in a lineup for different purposes: "sterilization," "super sterilization," and "organic matter decomposition"!

"Steril Radical N" - Long lifespan of over 10,000 hours of continuous lighting! - Reduced frequency of lamp replacements. - Fewer units compared to other companies' devices, advantageous for handling large water volumes! - Device design based on chlorine-resistant, heat-resistant spores. "Steril Radical S" - Realizes super disinfection by radicalizing sodium hypochlorite with ultraviolet wavelengths! - Further reduced the number of units compared to the N series while enhancing disinfection capability. - Super disinfection suppresses light recovery after disinfection. - Reduces membrane load caused by slime growth through super disinfection of organic matter in reused water. "Steril Radical SS" - In addition to the effects of the S series, the addition of trace amounts of ozone achieves organic matter decomposition from super disinfection! - By performing organic matter decomposition, it eliminates light recovery after disinfection. - Significantly extends the lifespan of the downstream activated carbon. - Excellent effects not only for disinfection but also for decolorization and deodorization!

Create clear water through a membrane.

Membrane filtration treatment is divided into microfiltration (MF), ultrafiltration (UF), and reverse osmosis (RO), and is currently one of the most spotlighted water treatment technologies. Compared to conventional processes such as coagulation, sedimentation, and sand filtration, it has achieved compact equipment and improved treated water quality, expanding its application range from seawater desalination and ultra-pure water production to wastewater reuse. [Features] ○ We select models according to the customer's required water quality. For more details, please contact us or download the catalog.

Efficiently treat contaminated water to purify it and create water that is suitable for the environment.

1. Are you having trouble with insufficient processing capacity of your wastewater treatment facilities due to increased wastewater volume? 2. Are you facing issues with the quality of discharged wastewater, such as unstable water quality? 3. Please consult us about the strain on your wastewater treatment facilities due to increased factory production, and how to comply with discharge standards. 4. Are you having trouble with substances that cannot be removed by your existing wastewater treatment facilities? - You have started using new chemicals. - You have begun producing new products in your production process, etc. 5. Are you facing challenges with the renewal of aging wastewater treatment facilities? - There is no space. You want to use more environmentally friendly equipment. You want to improve energy efficiency, etc. This device efficiently combines unit operations such as coagulation, sedimentation, flotation, and adsorption to purify various components of wastewater discharged from industrial sources, hospitals, laboratories, and research facilities, protecting the environment from contaminated water. It not only treats wastewater but also performs advanced processing to effectively utilize limited water resources as reusable water. [Features] - We propose the most efficient treatment by combining various treatment methods tailored to the type of wastewater and treatment standards.

Decomposition of refractory organic substances and sterilization with a UV lamp of 185nm + 254nm! Technical documentation for the ultraviolet-promoted oxidation device is currently being offered!

The "Ultraviolet Promoted Oxidation Device A.O.P" by Shouka Kogyo generates "OH radicals" by combining ultraviolet light at 185nm and 254nm with oxidants, enabling efficient decomposition of organic substances that have been difficult to remove until now. In groundwater treatment, complete color removal and disinfection are possible with the ozone generated simultaneously. In wastewater treatment, the lifespan of activated carbon can be significantly extended through regeneration reactions by OH radicals in the subsequent activated carbon tower. 【A must-see for those with these concerns!】 ■ Want to reduce the "load" on RO and ion exchange! ■ Want to remove the "color" from well water! ■ Want to improve the "organic matter concentration" before discharging wastewater! This device is recommended for achieving the decomposition of persistent organic substances and clarifying treated water. □■□■□■□■□■【Free technical materials available!】□■□■□■□■□■□ *Currently, we are offering free technical materials related to the Ultraviolet Promoted Oxidation Device "A.O.P." *If you are interested, please contact us with "Request for Technical Materials" noted. □■□■□■□■□■□■□■□■□■□■□■□■□■□■□■□■□ *For more details, please contact us or inquire through the catalog download.

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. This exhibition will be held simultaneously with the "Environmental Industry Trade Fair" taking place the day before. It will be held over the weekend, with many family-friendly events planned. We encourage those who usually find it difficult to visit to take this opportunity to come. Our product exhibition area is located about 10 minutes from the venue. We sincerely look forward to your visit.
