Abstract

The whole world is facing a global water quality crisis. Population growth, urbanization, and industrialization have accelerated the consumption of fresh water. The removal of harmful oil compounds resulting from today's industrial discharges in waters is necessary to protect humans, aquatic organisms, and water quality and prevent ecological damage caused by pollutants. The main goal of this research is to separate petroleum compounds (oil) from water using chitosan polymer membrane synthesized from shrimp shells and modified chitosan mixed matrix membranes. Shrimp shells were used to prepare chitosan and then the mixed matrix membrane of chitosan modified with titanium dioxide nanoparticles and cellulose acetate was synthesized. The performance of five different membranes made with the names M1, M2, M3, M4, and M5 was investigated, and the desired operating variables are oil inlet concentration, amount of nanoparticles in the synthesized membranes, and operating pressure. To investigate the process, the parameters of the water flux and the amount of oil pollutant removal were considered as the answer. According to the comparison between the five synthesized membranes, the M3 membrane containing 3 % of TiO2 nanoparticles with a removal percentage of 94.8% at 3 bar pressure, and 10% (v:v) of oil had the best performance.
