ANALYSIS OF THE MICROCONTROLLER-BASED ELECTROCOAGULATOR IN TREATING LAKE WATER

The Automatic Tubig Machine: A Microcontroller-Based Lake Water Treatment with Electrocoagulation is an integration of different ways of treating and purifying lake water from the Caliraya Lake emphasizing the performance of electrocoagulation in the whole process. Its main purpose is to treat water samples from different barangays surrounding Caliraya and Lumot Lake. The two adjacent lakes are strategically designed to gather water from the surrounding and use it to power the turbine, which generates electricity. The water from the lake is considered because the quality is deteriorating and needs some analysis.Aside from the sedimentary filters, electrocoagulation, reverse osmosis, and UV treatment are used in optimizing the quality of the water. The sedimentary filters are strategically designed and confined in a 3-inch diameter PVC piped for the natural horizontal flow of the water to be treated. The system is controlled using Arduino Mega especially in the control of the pump operation, sensors, and electro-coagulators. To avoid passivation on the aluminum pipes which are used as electrodes, the system is designed to change polarity every 30 seconds.The general water quality indicators such as pH level, turbidity, TDS, and coliform level are considered during the tests. The results were confirmed by the Department of Science and Technology (DOST). Treated water has had optimum value and is considered to be usable at homes and for cooking. The system is 92.66 % reliableand97.3% accurate.
