The Significant Role of pH in Pretreatment of SWRO Plant for Renewable Water Source

ABSTRACT:

This article highlighted some pretreatment methods to get potable water from Seawater. In the twentieth century, the ever-spreading urbanization and rapid increase in industrialization coupled with contamination of natural water sources through unprecedented use of chemicals have raised the demand for good quality drinkable water. The anthropogenic activities are continuously disturbing the physical, chemical, and biological composition of aquatic biota. To meet the demand of potable water, the process of Seawater Reverse Osmosis (SWRO) is now being used in developed countries. SWRO is a technique that removes all types of impurities, whether suspended or dissolved, including bacteria. This mini-review discusses some essential pretreatment parameters like pH, conductivity, turbidity and ionic strength which are involve in SWRO to convert Seawater into drinkable. Pakistan is now in line with other countries to install SWRO plants to remove water scarcity, especially in big cities like Karachi.
