By monitoring dissolved oxygen, we solve issues related to oxidation and foaming.

Are you having trouble with "foaming" and "oxidation" in your research and development or manufacturing processes? The cause may be related to "dissolved oxygen (DO)."

During the transportation and storage of substances that are prone to foaming or oxidation, chemical changes can occur that affect quality, so it is necessary to frequently measure the amount of oxygen. Orbisphere is a series of high-precision dissolved gas analysis instruments suitable for both liquid and gas phases. In addition to measuring dissolved oxygen (DO) in chemical and organic solvent applications, we offer a variety of installation methods tailored to different uses, including inline, online, and laboratory measurements, as well as portable models, explosion-proof models certified by IECEx and ATEX, and parts resistant to chemicals suited for the measurement samples, providing a rich lineup. Currently, we are introducing examples and topics related to oxygen measurement using Orbisphere. [Overview of Downloadable Materials] ■ Dissolved oxygen measured in many industrial fields ■ Examples of oxygen measurement applications in petrochemicals ■ Oxygen measurement in breweries ■ What is dissolved oxygen (DO: Dissolved Oxygen)? ■ List of application-specific products ■ Installation image of dissolved oxygen meters *For more details, please refer to the PDF materials or feel free to contact us.

[Application Example] Improving Factory Yield and Regulatory Compliance

Achieved through online TOC! Introducing a case study that improved factory yield and reduced product loss.

We would like to introduce a case study of the implementation of the "BioTector B7000" at a dairy processing company. The product loss in the company's wastewater not only reduced the factory's yield but also caused significant variability in the wastewater treatment process, leading to risks of environmental compliance violations and increased operational costs. After implementation, identifying the source of product loss reduced the variability in the load on the treatment plant, making compliance easier to achieve. 【Case Summary】 ■ Benefits of Implementation - Meets regulatory requirements regardless of the inflow of organic matter - Measures and optimizes the dosage of chemicals for organic matter in real-time - Improves factory yield and reduces product loss *For more detailed information about the case, please refer to the related link. For further inquiries, please feel free to contact us.

[Overseas Case] Maintaining Compliance for Phosphate Emissions

Accelerating the exploration and tracking of pollutants! Introducing examples of compliance with phosphate discharge regulations.

We would like to introduce a case study of the introduction of the "BioTector B7000" at the wastewater treatment plant in Oijen, Netherlands. This wastewater treatment plant did not have a component analysis device to monitor inflow and outflow water, and relied on regular inspections by a third-party organization. As a result, they were unable to respond swiftly to the sudden increase in C/N/P loads from industrial wastewater. After the introduction, it became possible to reliably monitor C/N/P levels during wastewater treatment. 【Case Overview】 ■ Challenges - Unable to respond swiftly to the sudden increase in C/N/P loads from industrial wastewater. ■ Results - It became possible to reliably monitor C/N/P levels during wastewater treatment. *Details of the case can be viewed through the related link. For more information, please feel free to contact us.

"Improvement of wastewater treatment through DO meter maintenance" Textile manufacturer - dyeing factory

In fact, "measuring the oxygen levels" was the key to the ongoing poor drainage treatment at the site!

We would like to introduce a case of maintenance and cleaning/recalibration of the DO meter at the wastewater treatment facility of a fiber manufacturer and dyeing factory. One day, an anomaly occurred in the biological treatment tank that processes factory wastewater. Various responses were attempted on-site, such as increasing aeration and adding chemicals, but no decisive improvement was achieved, and the overall instability of the treatment tank continued. We suspected a decrease in DO (dissolved oxygen) concentration within the biological treatment tank. Although no significant abnormalities were observed in the DO meter's displayed values, upon performing maintenance and cleaning/recalibration of the sensor, it became clear that the actual dissolved oxygen concentration was significantly lower than the measured values displayed. Based on this cause, we reviewed the aeration conditions, resulting in a recovery of microbial activity, which ultimately led to improvements in sedimentation. [On-site Issues] - Sludge does not settle in the downstream sedimentation tank. - Treated water is cloudy. - It seems that microorganisms are not functioning properly. *For more details, please download the PDF or feel free to contact us.*
