Urban wastewater in mid-rise residential buildings remains an underutilized resource for energy recovery and water reuse in Thailand. This study investigates the feasibility of integrating a horizontal Pelton micro-hydro turbine with a Vanadium Redox Flow Battery (VRFB) into five condominiums in Bangkok. The system was evaluated under simulated wastewater conditions, and four turbine configurations were tested. A Python-based model simulated VRFB performance under typical Southeast Asian load profiles. The horizontal Pelton turbine achieved peak output at 1.2 m³/h, generating 9.4 W with 72.4% efficiency, and averaging 0.67 kWh/day. The VRFB demonstrated a round-trip efficiency of 78% with consistent discharge over a 24-hour cycle. Additionally, 60% of treated wastewater approximately 2,124 m³/month was identified as reusable for non-potable applications. The results confirm that the hybrid system can operate effectively under variable flow conditions, with energy storage mitigating intermittency. While turbine performance is sensitive to hydraulic variability, pairing with a VRFB improves resilience and output stability. In conclusion, this hybrid system offers a scalable solution for decentralized resource recovery in urban Thai buildings, aligning with sustainable development and circular economy practices through combined water and energy management.
