Analytical Vision for Designing a Wastewater Treatment System Based on Reverse Osmosis and Renewable Energy is a research study authored by Osama M. Alkhawaldeh, Malek Khalaf Albezuirat, Yousf Jamal Okour, Mohamad Al-Rashaidah, and Asia Khalaf Albzeirat. The study presents an analytical framework for an integrated wastewater treatment system powered by renewable energy, combining reverse osmosis (RO) technology with hybrid solar and wind energy resources. Designed for the climatic conditions of Karak Governorate, Jordan, the proposed system evaluates the energy requirements for treating one cubic meter of wastewater, demonstrating that approximately 5.2 kWh of electricity can be supplied by three 400-W solar panels and a low-wind turbine, supported by an 8–10 kWh battery storage system to ensure continuous operation. The analysis highlights the feasibility of utilizing locally available renewable energy resources to power wastewater treatment processes while enhancing system reliability through energy storage. The proposed design offers a sustainable solution for water reuse in agricultural, domestic, and community development applications, contributing to improved water security, renewable energy utilization, and environmental sustainability.
