Enhancement Purified Terephthalic Acid (PTA) production capacity from 500,000 tons/year to 576,000 tons/year resulted in increase of water demand, so an optimization process for desalination and demineralization units is needed. This research aims to find how the desalination and demineralization optimization process is carried out to ensure the quantity and quality of water at PT INEOS Aromatics Indonesia. The research method used is descriptive qualitative by conducting literature studies, observing the optimization of desalination and demineralization processes, interviews and laboratory testing of water samples. The result of this research is that the desalination and demineralization optimization process has been successfully, with quantity of desalt water product is 197 tons/hour. Parameters for the production process, namely conductivity 0.8 µs/cm, copper (Cu2+) 0.005 ppm, sulfate (SO2-) 0 ppm, silica (SiO2-) 0 ppm and for domestic, namely temperature 30.8 oC, color 9 TCU, pH 6.8 ppm, odorless, tasteless, hardness (CaCO3) 0 ppm, turbidity 0.05 NTU, total dissolved solids (TDS) 0.8 ppm, nitrit (NO2-) 0 ppm, nitrate (NO-) 0.009 ppm, escherichia coli 0 CFU/100ml and total coliform 0 CFU/100ml. These values meet the quality standards set by the Amoco Research and Development and Minister of Health Regulation Number 32 of 2017.
