A comprehensive evaluation of the technical, economic, and environmental aspects of utilizing a PV-RO desalination process in a coastal region of Andhra Pradesh

Abstract

Abstract This paper puts forward a systematic study on the desalination plant feasibility at Chinni Rushikonda, Visakhapatnam, Andhra Pradesh, India. The water samples are collected from Rushikonda beach and tested in the nearby testing facility, National Collateral Management Services Limited. The salinity and TDS are within the limits and are encouraging for a Reverse Osmosis plant. A mathematical model of RO system is analyzed with different recovery ratio and feed salinity. Based on the energy requirements, the solar PV system is estimated and designed. An economic and environmental analysis is conducted to understand the capital cost, operating cost, profit, and CO2 emissions of the system. The analysis would examine the practicality and effectiveness of the system, along with the associated costs and benefits of implementing it. Additionally, the study would investigate the potential environmental impacts and carbon footprint of the PV-RO desalination process, with a focus on its sustainability and long-term viability.
