A Review Analysis – RO Waste Water Management System with Home Automation using Green Energy

Reverse Osmosis (RO) is a traditional technique for filtering water, especially for drinking purpose. Around 75% of contaminated water gets discharged as waste. The principal goal of this paper is to make a seamless system to manage the reusage of the effluent water where the user can get the real time feedback. The proposed system is integrated with ESP32 uses Bluetooth Low Energy and Wi-Fi (802.11 b/g/n) protocols to communicate devices with ESP RainMaker application. The RainMaker provides user the interface to control nodes and monitor data from diverse nodes, using HTTP/HTTPS or MQTT protocols. Initially an effluent water is stored in a common tank. The water level indicator is installed into a tank to monitor the level of water. A custom 12-channel (Single Pole double throw (SPDT)) relay module is connected to diverse household devices such as an electric bulb, fan, switch and solenoid valve. Once the water crosses the level the sensor will send the data and the pump turns on allowing user to manually control the on/off positions. Powered by solar energy, the system offers an eco-friendly solution by utilizing a solar-charged power bank. This setup presents a sustainable and energy-efficient approach to both water conservation and home automation.
