Ocean pollution is the major concern among all types of pollution. Oil floats on water and moves over aluminium discs considerably more slowly than water does throughout work because oil has a higher viscosity than water. This makes it easier to separate the water and oil. The objective of the present study is to design and develop the oil separator model in order to prevent pollution in ocean. The viscosity difference is the basic inspiration for this research. Oil floats on the surface because water is denser than oil. The qualities of this oil and water provide the foundation for this oil separation operation. The model uses four metal discs connected to a motor shaft to speed up the process of separating oil from water. The 12V DC battery powers the motor. The methods for recovering oil that were previously employed were ineffective and severely damaging to the environment. Burning any oil that had leaked onto the water was one of the most popular techniques. It produces a lot of harmful chemicals, such carbon monoxide (CO) and carbon dioxide (CO2) which is harmful for marine life. The results show that in order to utilise this oil, the oil separator model recovers around 85–90% of the oil, and produces no pollution.
