ASSESSMENT OF ZEOLITE USE FOR REMOVAL OF PETROLEUM COMPOUNDS FROM WASTEWATER

Abstract

ABSTRACT. Zeolites are types of inorganic porous materials that have been widely investigated and applied for their excellent sorption ability for wastewater treatment. Their low cost, safeness, natural abundance and accessibility make them good candidates for a large-scale application. Pollution generated by organic compounds, especially hydrocarbons from oil spills and crude oil refineries emerge as a great concern for aquatic life and the environment. The hydrophobic and highly stable molecules of hydrocarbons determine their persistence toward conventional methods involved in water treatment plants and accidental spills in oceans and seas. This paper presents the works that have been focused on implementation of natural and synthetic zeolites and their modified forms as well as zeolite composites for removal of hydrocarbons from wastewater.
