Automated real-time Monitoring and Controlling system for dye degradation from waste water

Abstract

The effluent coming out from textiles, paper, plastics, leather, food, and cosmetic products industries contain dyes and pigments. Efforts have been taken to process these effluents released into water bodies. The automated real-time monitoring and controlling system for dye degradation from such effluents is necessary for quality of purification. In present study, the microcontroller based photocatalytic experiments were carried out in a specially designed reactor. The sensors like pH, temperature, Light intensity, and level are attached to the reactor to monitor pH, temperature, decolorization of water solution. These sensors were connected through circuits to Arduino Uno and Arduino is connected to the computer through serial port. The real time data is displayed in graphical as well as numerical form. The data can be stored in csv format. Reactor tank inlet and outlet valves are also controlled through software. The parameters like the rate constant of the decolourisation reaction was determined using the Langmuir–Hinshelwood equation. By integrating sensors with the system into the treatment process, it is possible to continuously monitor and optimize the treatment process to ensure that it is effective at decolorizing the water.
