IRJET -Comparison of Desalination by Reverse Osmosis and Solar Powered Methods

This document compares two methods for desalination: solar powered desalination and reverse osmosis desalination. Reverse osmosis uses semipermeable membranes and applied pressure to separate fresh water from salt water. It is more efficient than solar powered desalination, achieving 95% efficiency compared to 88%. However, reverse osmosis requires large amounts of energy. Some rural communities use solar power as an alternative energy source for desalination. The document analyzes the materials and methods used in reverse osmosis and solar powered desalination systems. It also provides water quality parameters for water desalinated by each method, showing reverse osmosis produces lower mineral concentrations.
