[Topic Release] What are BOD, COD, and TOC in Industrial Wastewater? - Their Relationship and the Benefits of TOC Measurement

Solving issues such as "clogs, failures, and frequent maintenance/calibration" in wastewater containing chlorides and calcium, as well as in the measurement of high SS TOC.

Among the BioTector series, the B7000i is capable of obtaining accurate results even in particularly challenging applications. It comes standard with a self-cleaning feature, freeing users from the hassle of tube clogs and cleaning. With a sample tube and tube pump that have a diameter of 3.2mm, it is possible to measure soft samples containing fibrous solids, fats, oils, and salts with particle sizes up to 2mm without dilution. As a result, it addresses the issue faced by traditional combustion methods of underestimating particulate organic carbon (POC) and being heavily reliant on dissolved organic carbon (DOC) values.

"Online TOC meter" is widely usable for measuring inflow water, process water, reclaimed water, and wastewater.

The Hack Ultra online TOC analyzer BioTector B3500 series has achieved miniaturization and cost reduction by specializing in low-concentration samples, utilizing the same wet two-stage oxidation method as the higher-end B7000 model. It can be widely used for measuring inflow water, process water, reclaimed water, and wastewater. ■ The online TOC analyzer B3500 is available in three models to suit various applications: - B3500ul A TOC analyzer for low-concentration samples such as cooling water and RO water. It can be used without dilution and without blockage for soft particles up to 100 μm. - B3500c A TOC analyzer for standard samples such as reclaimed water and effluent. It can be used without dilution and without blockage for soft particles up to 100 μm. It can be configured with up to two flow paths as an option. - B3500e A TOC analyzer for high-concentration samples such as industrial wastewater. It features a self-cleaning function, resolving issues related to clogging of the sample tube. It can be used without dilution and without blockage for soft particles up to 100 μm.

The applications of Hyper CLT sheets are not limited to specific locations. Essentially, many civil engineering sites that have previously used steel plates are candidates for consideration. Wood CLT can be utilized in various places such as temporary roads, access routes, heavy machinery work yards, material yards, storage areas, temporary parking lots, and worker pathways. Of course, there are cases where steel plates are more suitable depending on site conditions, such as in areas with heavy loads or where heavy machinery needs to turn. The important thing is not to replace everything, but to use them appropriately according to the ground conditions, machinery, and intended use. Hyper CLT sheets are lightweight, easy to install and remove, and have unique characteristics of wood, such as reducing glare and metallic sounds, and fixing CO2. Furthermore, it is a **registered technology with the Ministry of Land, Infrastructure, Transport and Tourism NETIS "TH-250021-A."** By utilizing wood, NETIS, civil engineering, and CLT, it provides a new option for places that have previously used steel plates.

Event Date: October 7 (Wednesday) to October 9 (Friday), 2026 Time: 10:00 AM to 5:00 PM Venue: Intex Osaka Our company will be exhibiting at the 29th Monozukuri World Design and Manufacturing Solutions Exhibition, which will be held at Intex Osaka from October 7 (Wednesday) to October 9 (Friday), 2026. At the venue, we will showcase the upgraded "ReMacs Hybrid," as well as the eagerly awaited production management system for the precast concrete industry, "ReMacs TypePca," which will be unveiled for the first time following its release at the end of May! We will also display various solutions, including the newly equipped "AI Drawing Search System" with OCR functionality! We sincerely look forward to your visit.

In civil engineering sites, it is important to clearly communicate not only safety and workability but also "what kind of initiatives the site is undertaking." Hyper CLT mats are civil engineering mats that utilize wood CLT. They look significantly different from conventional steel plates, so when laid at site entrances, viewing routes, or material yards, they create a strong visual impact. In particular, during inspections by clients, site tours, and public open days for local residents, the use of wood, environmental considerations, and the application of new technologies can be conveyed in a "visible form." Additionally, they are lightweight and easy to install and remove, and they offer practical benefits such as reducing glare and metal noise, as well as CO2 fixation. Hyper CLT mats are registered with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS as "TH-250021-A." They combine wood, NETIS, civil engineering, and CLT, making them a new temporary material that can impressively convey the initiatives of the site.

Hotron Inc. has launched its new product, the "Vehicle Count Sensor CCS3"! This product is a ceiling-mounted sensor that combines infrared and radar technology. It reliably detects vehicles in both directions with a single unit, accommodating traffic during congestion and vehicle passing, thus achieving efficient occupancy management in large parking lots. Additionally, it can be utilized for exit warning purposes in addition to vehicle counting, contributing to the safe and smooth operation of parking facilities. 'Features' - Improved detection performance against changes in road surface during rainy weather by using both infrared and radar. - Equipped with IP67 waterproof and dustproof performance, making it effective even in salt damage areas. - Various settings can be configured from a dedicated app (for Android devices), with current settings easily understandable at a glance. - The base dimensions are the same as the previous model "CCS2," allowing for smooth replacement of existing equipment. *For more details, please refer to the product information, catalog download, or contact us.*
