EFFECTIVENESS OF HYDROELECTRIC GENERATOR USING WASTEWATER

Abstract

This study investigates the effectiveness of a small-scale hydroelectric generator powered by wastewater as an alternative energy source in emergency situations. An experimental design was employed to compare the electricity generation efficiency of municipal and industrial wastewater using a hydroelectric generator prototype. The prototype utilized a dynamo, inverter, and wastewater channeled through PVC pipes to create a flow that spins the turbine and generates electricity. The weighted mean approach was used to analyze data on electricity generation (watts) and Pressure-Flow-Speed Index (PSI) at different time intervals The findings revealed that municipal wastewater generated a higher overall weighted electricity output (22 watts) compared to industrial wastewater (15.75 watts). This suggests that the composition of municipal wastewater might be more suitable for driving electricity generation in this specific Hydro Electric Generator design. However, the current prototype's output was only sufficient to power a low-wattage LED light. Challenges identified include optimizing wastewater stream layout for efficient flow and maintaining stable PSI for consistent electricity production. The study recommends promoting the use of recycled materials for sustainable hydroelectric generator (HEG) construction and exploring potential applications of wastewater-generated electricity in public areas. Further research is suggested on portable HEG systems and other potential uses of this renewable energy source.
