| Water is one of our most precious resources and as much as wanted it to be, it is not an infinite resource. Water not only supports human life and activities but also helps to maintain the ecological structure. Water was used for everyday household purposes, such as bathing, dishes, flushing toilets, and washing machine. These activities are producing greywater. This project aims to develop the prototype of greywater treatment to conserve water and convert contaminated water from the washing machine (greywater) into clean water that can be used for watering the plants. Arduino Uno, pH sensor, ultrasonic sensor, solenoid valve, servo motor, and potassium alum are components and materials used in this project. This project was achieved by chemical filtration of the greywater using Arduino Uno. The greywater will be collected and identify the pH level by using a pH sensor. The quantity of potassium alum inserted in greywater was based on the accumulated pH value. The potassium alum was inserted into the greywater to eliminate the detergent in that greywater. The pH sensor was used once again to ensure the greywater are eliminated. The treated water was stored in a tank so that it can be used for the irrigation system, while the ultrasonic sensor was used to determine the level of treated water in the tank. |
