Implementation of Monitoring and Controlling of pH and TDS in Process Industry

Abstract

The reuse of water in process industries is used to increase the quantity of the water level. In process industries, the quality of water plays an important role and it also shows effects during the process. Continuous reuse of water in industries reduces the quality of water parameters. Some water parameters like pH and TDS are affected. Due to the reuse of water, the base level in the water gets increased and also the TDS level gets increased. This affects the quality of water, which leads to formation of mosses. Water parameters should be monitored and controlled. So, the buffer solution is added to the water which helps in reducing the base level of the water. If the buffer solution is added manually the acid level gets increased and leads to scale formation. So these water parameters should be monitored and controlled. The TDS level and pH level are monitored using TDS sensor and pH meter respectively. NodeMCU controls the solenoid valve which is connected with the sodium chloride buffer solution and controls the pH meter. Thus the quality of recycled water is controlled and monitored in the process industry and IOT is used to monitor the pH meter and TDS sensor from any location
