The "Reach Filter" is an activated carbon adsorption device used to remove chemical substances contained in treated water from manufacturing water, factory wastewater, drinking water, and sewage treatment. To demonstrate adsorption performance, the entire activated carbon in the adsorption tank is fluidized and mixed with washing water and bubbles of air for cleaning, allowing for the washing and removal of SS (suspended solids) adhering to the activated carbon, which can then be discharged outside the adsorption tank. Since the adsorption performance of the activated carbon can be maintained for a long time, running costs can be significantly reduced. It can also be utilized as regenerated carbon, making it an environmentally friendly device that effectively uses resources. 【Features】 ■ Improved adsorption efficiency and reuse of activated carbon ■ Reduced running costs and treatment costs for activated carbon ■ Increased work efficiency ■ Reduced ancillary equipment and maintenance management for the device *For more details, please refer to the PDF materials or feel free to contact us.

The activated carbon adsorption device "Reach Filter" resolves the issue of activated carbon solidification due to inadequate cleaning through dual cleaning with washing water and air bubbles, enabling long-term maintenance of activated carbon performance. It is suitable for a wide range of water treatment applications, from manufacturing water to factory wastewater, and both drinking and sewage water. By reducing the frequency of activated carbon replacement, it contributes to lower running costs and CO2 reduction. Additionally, when used in conjunction with our "sand filtration system," it is possible to supply treated water that meets drinking water quality standards. 【Features】 ■ Reduction of costs and labor through decreased activated carbon replacement work ■ Prevention of activated carbon solidification due to inadequate cleaning ■ Effective utilization of micro and sub-micro pores within the activated carbon through unique cleaning methods ■ Compact design *We are currently offering materials that introduce the cleaning process and representative water treatment processes (sewage treatment facilities / final disposal sites) with diagrams!

The activated carbon adsorption device "Reach Filter" solves the problem of activated carbon solidification due to inadequate cleaning through a dual cleaning process using cleaning water and microbubbles, enabling long-term maintenance of activated carbon performance. By reducing the frequency of activated carbon replacement, it significantly lowers running costs such as filter replacement expenses and industrial waste disposal fees. It is capable of handling a wide range of water treatment applications, from manufacturing water to factory wastewater, as well as drinking water and sewage. 【Features】 ■ Contributes to CO2 reduction ■ Extends the lifespan of activated carbon replacements ■ There are cases where the lifespan of activated carbon used in food company clean water treatment facilities has been tripled (from 1 year to 3 years) ■ Unique cleaning allows effective utilization of micro and sub-micro pores inside the activated carbon ■ Compact design considering installation space ★ You can view product materials with cost reduction case studies and a collection of installation examples of sand filtration systems that include this product by downloading the PDF. (For more detailed information about cost reduction case studies, please contact us) *If you submit the "model selection sheet" included in the product materials, we will propose specifications that meet your requirements.

In the water purification industry, the removal of harmful chemicals from water is essential for the safe supply of water. In particular, organic substances and chlorinated compounds present in raw water not only worsen the taste and odor of water but also raise health concerns. If proper water purification treatment is not applied, it may increase health risks for consumers. Our granular activated carbon adsorption system has been developed to address these challenges. 【Usage Scenarios】 - Drinking water treatment - Industrial water treatment - Wastewater treatment 【Benefits of Implementation】 - Improvement of water quality - Reduction of running costs - Effective use of resources

From measures against organic substances such as COD, n-Hex, and TOC, to measures against PFAS (per- and polyfluoroalkyl substances). We propose a supply and adsorption system using activated carbon to respond to the diversifying challenges of water treatment. ________________________________________ ACF (50% wet powdered activated carbon supply system) Widely adopted in small to medium-sized water purification plants. Stable and continuous supply of activated carbon. In recent years, the problem of musty odors has become apparent in various regions due to decreased precipitation. ACF is a supply system that slurries 50% wet powdered activated carbon and enables continuous injection. ________________________________________ RFC (granular activated carbon adsorption system) For PFAS measures and organic substance removal. New type of activated carbon adsorption system. RFC is a high-performance adsorption device that uses granular activated carbon. It can address organic fluorinated compounds (PFAS), including PFOS and PFOA. What is PFAS? PFAS (per- and polyfluoroalkyl substances) are a group of organic compounds that are resistant to decomposition.
