[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.

TOC analyzer with internal automatic cleaning function that reduces clogging and maintenance hassle! Demo units available for loan.

The online TOC analyzer BioTector offers several models tailored to your usage needs. The 'B7000i' is an online TOC analyzer designed for high-concentration wastewater, equipped with an internal automatic cleaning function that minimizes clogging and maintenance hassles. It can measure wastewater containing soft particles up to 2mm in diameter without dilution, allowing for automatic measurements without downtime, without the need for cleaning clogs or stopping the device. Depending on the application, various models can be selected for COD/BOD/TC, with one unit capable of handling up to 6 channels. Explosion-proof models (overseas explosion-proof) are also available. It employs a unique wet two-stage oxidation method. If there are challenges with oxidation power in the wet method, this approach overcomes those issues. 【Features】 ■ Internal automatic cleaning function ■ Reduces clogging and maintenance hassles ■ Annual operating rate of over 99% ■ Various model selections available based on application *For more details, please refer to the catalog.

In civil engineering sites, there are many instances where temporary roads, access roads, heavy machinery work yards, and material storage areas use ground plates. While conventional steel plates are practical, they can sometimes fail to leave a lasting impression when it comes to the appearance of the site and conveying the company's initiatives. Hyper CLT ground plates are civil engineering materials that utilize wood CLT. As ground plates with the texture of wood, they can be used as a substitute for steel plates, for mud prevention, ground protection, and ensuring pedestrian pathways. By introducing them in visible areas such as site entrances, morning assembly locations, and around break areas, it becomes easier to create an impact that differs from traditional sites. The 5×10 plate weighs about 230 kg, and the 5×20 plate weighs about 460 kg, making them lightweight and easy to handle even with small machinery, which helps reduce construction burdens. They also offer advantages such as glare reduction, noise reduction, and environmental considerations unique to wood, making them suitable for innovative public works projects. Registered as a Ministry of Land, Infrastructure, Transport and Tourism NETIS technology "TH-250021-A," they are recommended for companies aiming to create a distinctive impression at their sites. We can also provide consultation for small lot introductions and suggest usage methods tailored to site conditions. Why not add a clear change to your civil engineering site with these new wooden ground plates?

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding methods for repairs can change the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Waterworks Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for metal crack repairs without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even 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 or download the catalog.

In facilities operating nurse call systems, we have made the bed exit sensor wireless, allowing it to notify in conjunction with the nurse call system. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensor wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. This helps prevent accidents caused by falls, slips, or wandering, contributing to the efficiency of medical operations. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ The bed exit sensor notifies wirelessly in conjunction with the nurse call system. ○ Up to 5 transmitters can be registered with a single receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.

[To the owners of parking lots and parking lot construction companies] "I’m worried about not colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures using various sensors and alerts the surroundings with LED lights and buzzers. The device consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *Please note that a separate control panel is required to include the controller and switching power supply (24V) when using the exit warning system. *We kindly ask that customers arrange for the switching power supply (24V), LED rotating light, control panel, circuit breakers, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. We hope this will contribute to safer vehicle passage for everyone. ◎ For more details, please contact us or download the catalog.
