Real-time VFA monitoring device to maximize the efficiency of methane fermentation in anaerobic digestion.

The online VFA meter EZ7200 series is a high-performance online titration device designed for monitoring wet anaerobic digestion tanks. It proposes a new management method for medium to large-scale anaerobic digestion processes. In biomass power generation, industrial wastewater, and sewage treatment, the anaerobic treatment of wastewater and sludge in fermentation tanks involves the breakdown of very complex organic carbon compounds, which presents challenges. Real-time measurement of VFA (volatile fatty acids) is effective for stabilizing the methane fermentation tank in anaerobic treatment. Relying solely on pH measurement and sampling can make it difficult to monitor the conditions inside the fermentation tank, depending on the timing. The ideal pH value inside the fermentation tank is said to be between 6.5 and 7.5, but measuring pH alone is not sufficient; adequate buffering capacity [total alkalinity TAC (also referred to simply as alkalinity)] is necessary to compensate for changes in acid concentration. By continuously monitoring VFA, which are intermediate substances during methane fermentation, it contributes to maintaining a more stable fermentation tank and maximizing gas production. By conducting online measurements at 10-15 minute intervals, it becomes possible to anticipate various events within the digestion tank in advance.

Improved yield in the factory! Contributing to an increase in overall equipment output and reducing energy costs at the wastewater treatment plant!

We would like to introduce a case study where Carberry Company utilized 'BioTector' to acquire real-time data necessary for continuous business improvement. The company implemented this product to meet the environmental requirements of the IPPC license and to increase overall plant production by reducing product loss due to wastewater. By fundamentally reducing product loss in the production department, it contributed to an increase in overall equipment yield, resulting in a significant reduction in energy costs at the wastewater treatment plant. 【Case Overview】 ■Purpose of Implementation - To increase overall plant production - To reduce operational costs of the wastewater treatment plant ■Results: Contributed to an increase in overall equipment yield and significantly reduced the load on the wastewater treatment plant *For more details, please refer to the related links or feel free to contact us.

The glass pot lid has a hydrophilic heat-resistant coating, allowing you to check the cooking state without any fogging.

"Because it's an invisible place, we won't overlook it." Japan's climate is characterized by high temperatures and humidity, and particularly after typhoons and heavy rains, the conditions can be harsh for homes. It's not just the roofs and exterior walls that are affected by rain and wind. The area beneath the floor is actually the most susceptible and often overlooked point. This time, we will explain the "checkpoints for under the floor" that should be confirmed after a typhoon or heavy rain, the "responses" if abnormalities are found, and measures for preventing recurrence.

Explosion-proof motors available in stock We will deliver within 7 days to meet your delivery schedule. 【What is an explosion-proof motor?】 In factories and plants, flammable gases and vapors are present. When these mix with air and come into contact with an ignition source, an explosion or fire can occur. This motor is designed with measures to eliminate such ignition sources. 【Available stock models】 ■ Pressure-resistant explosion-proof motors, explosion-proof grade d2G4 - Foot-mounted type, output 0.4 to 3.7 kW, 4 poles - Flange type, output 0.4 to 0.75 kW, 4 poles ■ Increased safety explosion-proof motors, explosion-proof grade eG3 - Foot-mounted type, output 0.2 to 0.75 kW, 2 and 4 poles - Flange type, output 0.2 to 0.75 kW, 2 and 4 poles

As part of the "Hometown Ibara Future Creation Human Resource Development Project," we welcomed local elementary and middle school students to the special summer program "Ibara Job Exploration Tour 2025," a collaboration between the Ibara City Chamber of Commerce and the Corporate Branding Committee. We conducted a presentation that clearly and enjoyably introduced how our technology supports society, allowing the children to learn about the appeal of manufacturing and the significance of working while interacting with actual devices and products. Through this initiative, we hope to deepen our connection with the community and nurture the curiosity of the children who will carry the future. We sincerely thank everyone who participated, as well as all those involved in planning and organizing the event.

We will disclose the interim financial results for the fiscal period ending December 2025.
