AbstractThis study presents an Arduino-based transportable solar-rechargeable water purification device using Biosand filtration and Ultraviolet Light treatment with Android connectivity provided for monitoring and maintenance. Biosand filtration is responsible for removing pathogens and eliminating physical parameters like turbidity, iron, color and odor. However, Ultraviolet Light treatment is added to the process for more efficient removal of biological contaminants. Water parameters such as pH and turbidity level are monitored real-time throughout the purification process in an application installed on an Android unit connected to the device via Bluetooth. The process continues until acceptable range of parameters for drinking water are met according to Philippine National Standards of Drinking Water (PNSDW). Accuracy of the device is determined by comparison of results with the parameters provided by PNSDW. Physical parameters like pH, turbidity, Total Dissolve Solids (TDS) and microbiological parameters such as Fecal Coliform, Total Coliform and Heterotrophic Plate Count (HPC) of the output water from the device are also tested by a water testing laboratory for verification of results. The device was proven to be efficient and has the capability to produce potable water.
