In this stuefy, the economic feasibility assessment and comparative carbon footprint (CF) analyses of using an optimized reverse osmosis (RO) system to remove water from milk were realized. The objective is minimizing the total lifetime cost (LC) of the RO system, and the objective function is made up of two parts: an initial cost (Iq part that depends on the area of the membrane, and an operating cost (OC) part that depends on the transmembrane pressure. Since area and pressure are reversal proportional, increasing the IC would reduce the QC or vice-versa. Hence, the total cost must have a minimum point with respect to area, which was our decision variable. The physical data regarding the process were acquired from a company operating in Izmir province Turk . The model was solved by using a commercial available optimization software. The optimum area was found as 22.8 nl (245.417 JI). The results show that, far the given flow rates, the total LC of the RO system is around $400,000 whereas using a natural gas-based evaporation system with 85% efficiency for the same duration has a cost of approximately $1,600,000.00 thereby showing that RO system is economically feasible. Furthermore, the use of the RO system leads to lifetime CO2 emission reduction of13.5 k ton (29762405.4 lb) when compared to the natural gas-based evaporation process. These results show that RO systems have the potential to be used in the dairy industry thanks to the economic and environmental benefits they provide.
