This review article explored the origin and characteristics of oil
particles in the wastewater. Various existing methods for its treatment
and removal were discussed. In the oily wastewater treatment,
choice of the best technology is based on wastewater
chemistry, cost-effectiveness, space availability and discharge
plans. Natural fibres are among the alternatives for oily wastewater
treatment for their simplicity, excellent oil removal properties,
environmentally friendly characteristic and easy availability and
feasibility. Upgrading of these fibres through chemical modifications
could further enhance their oil adsorption capability
