Oil-water separation by usingceramic microfiltration membrane

Rapid industrial growth generates large quantities of oily wastewater, such as oil, gas, petrochemical, and food industry. Therefore, the process of separating oil from water has been very important lately, especially for researchers due to a major impact on the environment and human health for that oily wastewater. Hence, the use of pre-treatment separation for the removal of oil from water is becoming very important in these industries. There are several methods available for pre-treatment of oil-water emulsions including sand filter, ultrasonic separation and coagulation method. But choosing the best one depends on their relative ability to remove the oil as well as the cost of the method. Another advanced method of separating oil from water are pressure-driven membrane separation processes. However, a major problem when using membrane processes to treat wastewater is fouling of the membrane surface.
