This project aims to achieve 3 objectives. First, design a sustainable kitchen wastewater management system that can reduce Fat, Oil and Grease (FOG) discharge into the sewer system. Second, to upgrade the Eco-Grease Trap v1 through IoT integration. Lastly, to develop a digitalised kitchen wastewater (FOG) management system using the ‘Smart City’ concept. Initial Design: Eco-Grease Trap v1 was designed to tackle unmanaged FOG entering the sewer systems. The EGT-v1 incorporates two main key features - Detachable Modular Walls: EGT-v1 features fully removable divider panels. This provides 360° access to the tank, significantly reducing maintenance time and preventing bacterial growth in hard-to-reach corners. - Eco-Filter: In order to replace synthetic, non-biodegradable filters, natural material were used. - Oleophilic Natural Media: The primary filtration stage uses Coconut and Kapok fibers. They absorb and retain high volumes of oil while repelling water, making them a superior biodegradable alternative to plastic mesh. - Odor Neutralization: A final stage of Activated Carbon Charcoal acts as a natural purifier. Upgrade: EGT-v2 improvises by transforming it into an Internet of Things (IoT) device. The upgrade focuses on the following key functions: - Automated Valve: To prevent accidental overflows, EGT-v2 introduces a mechanical "stop" mechanism. If sensors detect a "Dangerous Zone", the ESP32 triggers a physical mechanism to stop the kitchen wastewater inflow. - Real-Time Turbidity & Level Monitoring: Utilizing an ESP32 microcontroller and turbidity sensors, the system provides a live assessment of water quality. - Smart City Connectivity: By utilizing the MQTT protocol, EGT-v2 creates a "communication bridge" between F&B outlets and local councils. All maintenance logs and water quality data are digitized and uploaded to a central dashboard, fostering transparency and allowing local councils to monitor city-wide waste compliance in real-time.
