  The main goal of this work is to present a sustainable modified desalination scheme which incorporates a chemical conversion unit (CCU) that handles the reject brines exit the desalination unit. With the available technology, we have today this can change the paradigm of “waste product” into a “resource” aiming for the utilization of brine, as a feed stock for magnesium production plus other chemical products to take place. It is a chemical process that involves bubbling CO2 gas in “ammoniated” brine. The brine used contains about 25% NaCl and is obtained by concentrating the reject brine before entering the CCU. The proposed method, offers a vehicle to dispose reject brine and to utilize it, at the same time, to recover and extract valuable minerals found in these rejects. In the proposed method, ammonia used in the chemical conver.. View More»
