Design and Implementation of Sewage Treatment Plant Using IoT

With the scarcity of fresh water all over the globe, wastewater can be cleaned using specific chemicals in sewage treatment plants, which aid in water recycling. This would increase the limited freshwater supply and postpone further investments in water treatment facilities. IoT sensors have been proven to be crucial for the STP to function effectively. It is employed to measure water’s alkalinity, acidity, pH, total hardness, dissolved oxygen, COD, chlorides, and other properties. These specifics will further aid in evaluating the water’s state to determine whether it may be recycled. Relays are used to link specific IoT sensors to the ESP-8266 microcontroller. Sensors like pH sensors, temperature sensors, chemical sensors, multi-parameter sensors, etc., can be used for this purpose. With adequate internet connectivity, these sensors will sense the parameters, send the data to a sensory node for processing, and then store the processed data in the cloud for later access. IoT sensors will find changes in various metrics at various purification processing phases. This information that will be kept in the cloud will provide specifics and statistics regarding pH levels, temperature, chemical reactions, and other factors, making it possible to monitor the STP from any location in the world.
