Improvement of Drinking Water (Surface and Ground) Quality Beneficial to Human Use

Water supply is a worldwide issue that is becoming increasingly evident in many countries. From a socio-economic standpoint, increasing water resources by reuse can strengthen the infrastructure of a country, and improve the lives of its people. We have been facing increasing problems due to the pollution of the surface and ground waters. Major water bodies receive increasing loads due to the inadequate and insufficient treatment facilities. Due to the geography and climate variations around the world, approximately 70% of the renewable waterresources are unavailable for human use. 

Lack of a sufficient quantity of water suitable for irrigation and drinking can lead to food shortages and health concerns for millions. In addition, water scarcity can stifle a nation’s economy, fuel conflicts, and negatively impact the environment. The global water supply is being stressed further, as human population continues to grow exponentially. Consequently, there is an urgent need to increase water. The standard Reverse Osmosis (RO) membrane is a Thin Film Composite (TFC), and its introduction in the late 1970s was a major advance in membrane preparation, resulting in greatly improved permeability and retention. Recently, there have been new developments involving thin film nano-composite (TFN) RO membranes. Read more.................
