Regularly performing membrane cleaning can prevent issues such as poor foaming, blockage, and clogging in advance.

By using a commercially available nylon brush to brush the membrane, you can prevent poor foaming of the membrane in advance. This is an easy cleaning method, so please be sure to do it regularly.

One reason why EDI Japan is chosen among many aeration devices is that the membrane is easy to replace.

If performance from the initial introduction can no longer be maintained due to degradation or clogging, or if you want to change the material of the membrane, it is necessary to replace the membrane. Replacing the membrane does not require any special skills as long as you have the appropriate tools. EDI Japan contributes to energy-saving and stable operation of wastewater treatment facilities. *Please refer to the PDF materials and feel free to contact us.*

Up to 50% energy savings compared to conventional products! An aeration device that enables high-efficiency wastewater treatment and energy conservation.

"FlexAir" is a membrane-type ultra-fine bubble aeration device widely used around the world, including in the United States, as an aeration device for wastewater treatment and other applications. Thanks to its high oxygen dissolution efficiency, it can achieve energy savings of 20-50% compared to conventional products! Additionally, its mechanism to prevent clogging, which is common in fine bubble diffusers, helps avoid maintenance hassles and decreases in aeration efficiency! We offer a wide range of products at low prices tailored to the specific needs of your site, including desired strength, aeration efficiency, and ease of installation. 【Features】 - Up to 50% energy savings in wastewater treatment costs compared to conventional products! - Clogging prevention function to maintain aeration efficiency! - A rich lineup and low prices tailored to various applications! *You can download the product lineup catalog from the link below. ★We are currently looking for sales agents. Please feel free to contact us★

• Aeration/air diffusion equipment

Active in wastewater and drainage treatment! Enables energy saving, reduced maintenance, and cost reduction.

This is an introduction to the comprehensive catalog of ultra-fine bubble aeration devices. This product promotes energy conservation and has three main features: "energy saving," "low maintenance," and "cost reduction." You can select the most suitable aeration device for your treatment facility based on the airflow and oxygen dissolution efficiency of the five types of aeration devices, allowing you to build the best aeration system. *For more details, please contact us or download the catalog. ★We are currently recruiting sales agents.

• Aeration/air diffusion equipment

This is a small, round aeration device (aeration pipe) that allows for installation in every corner and uniform aeration.

This is a representative disc-type ultra-fine bubble diffuser of the membrane type. It can be used as a replacement for conventional coarse bubble aeration devices as an energy-saving measure, or as a substitute for conventional aeration pipes to prevent clogging. 【Features】 - Compact circular design allows for installation in corners - Enables uniform aeration - Available in two types: high oxygen dissolution efficiency type and high airflow type The former has approximately 30% higher oxygen dissolution efficiency (at a depth of 4.6m in clean water) *For more details, please request documentation or download the catalog. ★ We are currently seeking sales agents. Please feel free to contact us! ★

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

We will be exhibiting at the "New Manufacturing and New Services Exhibition for Small and Medium Enterprises" from December 16 (Tuesday) to 18 (Thursday), 2025. Please feel free to stop by our booth. We look forward to meeting everyone.

Thank you very much for your continued support. Donaldson Japan Co., Ltd. will be closed during the following period: From April 25 (Saturday) to May 6 (Wednesday). Inquiries made during the closure will be answered sequentially after May 7 (Thursday). We sincerely apologize for any inconvenience this may cause. Thank you for your understanding and cooperation.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
