To the personnel in charge of drainage treatment maintenance and environmental management, we would like to introduce a case regarding the proposal for the introduction of a coagulant dosage control device. Coagulants are essential for wastewater treatment in manufacturing sites, but traditionally, a fixed amount was added regardless of the characteristics of the raw water. This led to issues such as wasted chemical costs and instability in floc quality. To address these problems, we proposed the introduction of a coagulant dosage control device. By implementing this device, it became possible to optimize chemical usage while improving treatment efficiency. [On-site Challenges] ■ The chemical dosage is fixed even though the concentration and load of the raw water fluctuate daily. ■ There is a tendency for coagulation to be excessive or insufficient, leading to inconsistencies in treatment efficiency. ■ Wasted chemical costs and instability in floc quality. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study on the introduction of high-efficiency mixers to reduce electricity costs at a wastewater treatment plant. To reduce electricity costs, it is first necessary to identify areas with high electricity consumption within the wastewater treatment plant. A field survey was conducted to determine where the load is concentrated throughout the entire wastewater treatment process, from the neutralization tank to the sedimentation tank. By replacing the mixers used for aeration in the raw water tank and aeration tank with high-efficiency mixers, we successfully reduced electricity costs. For a customer in the paper industry, the annual electricity cost was reduced from 860,000 yen to 670,000 yen, achieving a 50% reduction. [Case Summary] ■ Benefits of introducing high-efficiency mixers - In addition to reducing electricity costs, switching to high-efficiency mixers prevents sludge settling, ensures uniform mixing, and suppresses scum formation. - We offer a wide range of solutions for stirring, mixing, and generating water flow in various water-related facilities across industrial and water quality environmental sectors. *For more details, please download the PDF or feel free to contact us.

We proposed a review of wastewater treatment to the person in charge at automotive parts manufacturers, painting factories, and electrodeposition painting lines that have wastewater treatment facilities. We received inquiries about wanting to improve the water quality of treated water, which sometimes exceeds the standard values. Upon inspecting the site, we found that multiple equipment-related issues were overlapping. We simultaneously proposed and implemented three points: updating the dewatering machine, relocating the piping in the aisle, and installing a new diffuser along with updating the blower piping. As a result, the water quality stabilized, there were no longer any exceedances of the standard values, dewatering treatment kept pace, and the accumulation of sludge was resolved. [On-site Issues] ■ The water quality of treated water sometimes exceeds the standard values, and improvements are desired. ■ When problems occur with wastewater treatment, it affects the entire factory's operations, so a fundamental review is needed. ■ There are concerns about the safety of workers as they might trip over the piping in the aisle. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study of the implementation of an automatic control system for industries such as aluminum processing, metal processing, surface treatment, and extrusion molding, where pH management of factory wastewater is required. We received inquiries expressing concerns that the pH of the wastewater sometimes shows abnormal values and that there might be a risk of it flowing out externally. Abnormal pH levels in wastewater can occur suddenly, and there are limitations to monitoring and responding manually. Our proposal was to implement a system that automatically controls an electric valve in conjunction with the pH meter readings. After implementation, we achieved zero outflow of abnormal water, and real-time responses to pH anomalies became possible. 【Challenges on-site】 ■ The pH of the wastewater sometimes shows abnormal values, raising concerns about potential external outflow. ■ If water exceeding the standard value were to flow out, it could lead to environmental standard violations or issues with neighboring areas. ■ Continuous monitoring by human resources is difficult, so we want to implement automatic safety measures. *For more details, please download the PDF or feel free to contact us.
