Thesis Abstract

Abstract
Water scarcity is a critical global issue that affects millions of people worldwide, particularly in arid and semi-arid regions. Desalination technologies have emerged as a sustainable solution to address water scarcity by converting seawater or brackish water into potable water. However, traditional desalination processes are energy-intensive and often rely on fossil fuels, contributing to environmental degradation and greenhouse gas emissions. In this context, the design and optimization of a solar-powered water desalination system present a promising approach to produce clean water sustainably using renewable energy sources. This thesis focuses on the design and optimization of a solar-powered water desalination system to enhance water production efficiency and environmental sustainability. The research methodology involves a comprehensive literature review to analyze existing desalination technologies, solar energy systems, and optimization techniques. By integrating solar energy with desalination processes, the proposed system aims to reduce energy consumption, operating costs, and environmental impacts associated with conventional desalination methods. Chapter 1 provides an introduction to the research topic, background of the study, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of key terms related to solar-powered water desalination systems. Chapter 2 presents a detailed literature review covering ten key aspects related to desalination technologies, solar energy systems, optimization methods, and their integration for sustainable water production. Chapter 3 outlines the research methodology employed in designing and optimizing the solar-powered water desalination system, including system modeling, simulation, data collection, analysis, and optimization techniques. This chapter also discusses the selection of materials, components, and design parameters for the proposed system. Chapter 4 presents a comprehensive discussion of the research findings, including the performance evaluation, efficiency analysis, cost-benefit assessment, and environmental impact of the solar-powered water desalination system. The results highlight the potential advantages of integrating solar energy with desalination processes in terms of water production, energy savings, cost-effectiveness, and environmental sustainability. Chapter 5 concludes the thesis with a summary of key findings, implications for practice and policy, recommendations for future research, and concluding remarks on the design and optimization of a solar-powered water desalination system. This research contributes to advancing sustainable water desalination technologies and promoting renewable energy solutions for addressing water scarcity challenges globally.
