Modified Tung Oil and its application in Oil-Contaminated Water treatment

Abstract

The wastewater issued from industrial firms, particularly in the fields of electronics and mechanics is often contaminated with oil/grease (used in maintenance of components, equipment and materials,...) and the oil amounts is also exceeding the permitted threshold for industrial wastewater. The treatment of such wastewater is often complex with several steps and needs specialized polymers that are imported, normally derived from petroleum and expensive. In this study, we propose to synthesize oil-water separating agents from natural plants (tung oil) that are abundant in Vietnam and environmentally friendly. The use of these products with a simple separation process enables the effective separation of the contaminating oil in water.
