Establishing an Internet of Things (IoT)-enabled solar-powered smart water treatment system

The primary sources of potable water are groundwater, rainfall, waterfalls, and surface water such as rivers and lakes, etc. However, the water from these sources is chemically, physically, and biologically contaminated due to geological conditions, industrial pollution, and domestic contamination. The most prevalent contaminants in water are arsenic, pathogens, organic compounds, metals, etc. Iron concentrations in some regions of Bangladesh exceed the WHO limit of 0.3 mg/L, with median levels above 2.0 mg/L. Approximately 67% of the population of Bangladesh drinks contaminated water. Chemically contaminated drinking water has severe health repercussions. This paper has outlined an automated water treatment system facilitated with auto dosing and auto filter cleaning system. The entire procedure is managed by programmable logic controller (PLC). With a SCADA (Supervisory control and data acquisition) system, the pump and many parameters may be monitored and controlled through the internet. We have also estimated required numbers of solar panels based on accurate load calculation to ensure our designed plant can be powered by solar energy. This suggested plant can therefore be placed in any isolated area.
