Abstract

This paper is a detailed study of the need to find and implement new solutions for water filtration and the promotion of modern techniques that are more effective than traditional methods. As a result of extension waste water pollution as well as low efficiency through classical filtration means, more and more research is being discussed and researched worldwide, focusing on the use of hybrid membranes for seawater desalination. Hybrid membrane filtration processes present a number of advantages including superior water quality but also reduced energy consumption that was needed in previous purification processes. This review describes the water desalination process in detail by looking at the relationship between membrane module operating parameters and energy efficiency. The methodology and the experimental installation of the desalination process will be presented in part. The results of the study clearly showed that the combined use of membrane processes is efficient due to the flexibility of exploitation, the low acquisition costs and the high degree of water filtration through low energy consumption. A major advantage in the use of membranes is that the energy required to conduct filtering processes can be obtained from solar, wind energy, which means significant environmental benefits by promoting "green energy". The worldwide implementation of the use of membrane water desalination methods also involves increasing the percentage of fresh water, so this is a solution to be considered in present and future research.
