Water Reuse (WR): The Ultimate and Vital Solution for Water Supply Issues

Abstract

Nowadays the humankind is urgently invited to make available for potable use satisfactory quantities of good quality water to its increasing population. There is a big effort by the water treatment specialists to analyze the solutions the humankind has at its disposition to respond to these risks. The contribution of water reuse (WR) would be great in the humankind's water tomorrow. This review aims to discuss the growing WR technology as a future solution for water supply issues. WR is broadly applied by industries to decrease the consumption of clean water. WR process should employ treated wastewater mixed with surface water at a certain proportion depending on the degree of purity of the treated water and assuring the dilution effect. WR should not employ at any case only wastewater, for safeguard reasons and psychological effects. WR should be obviously more sophisticated than both water treatment and wastewater treatment since pathogens contamination and chemicals presence can be there most elevated. Since pharmaceutical products and cosmetics substances at trace levels are found in tap water, should we assist to a new formulation of water treatment technology? This will be feasible if water treatment/wastewater treatment/WR would be merged in a super and highly standardized water/wastewater treatment technology, as a future trend.
