Membrane Development and Its Hybrid Application for Oily Wastewater Treatment: A Review

Abstract

The treatment of oily wastewater emitted from diverse industrial sources is significantly fundamental to keep environmental sustainability as well as human health. Membrane technology as one of the propitious methods has been used and developed in many ways for treating oil-containing water and wastewater. However, membrane fouling is an unavoidable occurrence regardless membrane materials including polymeric, ceramic, and metal based-membrane. In addition to this matter, hybridization system in membrane usage has attracted an increasing interest due to its benefit in decreasing fouling rate. In this paper, we begin with an overview of membrane application and its materials as well as its existence along with other existing treatment methods. Further, we specifically provide discussion into the application of hybrid membrane system in treating oily wastewater. According to the literature review which has been discussed here, conclusions then are properly drawn to highlight hybrid membrane systems that can amplify membrane resistance on fouling phenomenon.
