Water-related IoT: Water Quality Management System (COD, Total Nitrogen, Total Phosphorus)

Water-related IoT: Water Quality Management System (COD, Total Nitrogen, Total Phosphorus)

■■ Cloud service for automating water-related operations ■■

● The total water quality regulation is a system that monitors the total amount of organic pollutants flowing into closed coastal areas (Tokyo Bay, Ise Bay, Osaka Bay, Seto Inland Sea). ● Facilities that discharge into rivers flowing into the above areas are required to monitor COD, nitrogen, and phosphorus in their effluent. ● These measurements and calculations of load must be performed using testing methods based on JIS standards, and the results need to be recorded. ● The obligation to measure the pollution load of COD, nitrogen, and phosphorus is as shown in the table below. ● The total water quality regulation is imposed on facilities with a discharge volume of 50 m³ or more within closed coastal areas. Measurement data can be viewed and managed in real-time on client devices (PCs, smartphones, tablets), which can help improve the efficiency of water quality management operations. ▶▶▶ For more details, please download the PDF ◀◀◀
