ABSTRACT
Sponge-gourds, the fruit of Luffa cylindrica, are widely used throughout the world. It is an annual climbing crop which produces fruit containing fibrous vascular system. Produced water is any water that is present in a reservoir with the hydrocarbon resource and is produced to the surface with the crude oil or natural gas. The residual metallic ion concentrations were determined using an Atomic Absorption Spectrophotometer (AAS). The physico-chemical properties of Produced water before discharge or reinjection into the waterways and reservoir and after treatment with luffa cylindrica were also determined. The percent removal of metal ions present in the produced water under study were 92.31%, 88.64%, 85.71% and 66.67% for Cr3+, Zn2+, Pb2+ and Cd2+ respectively. There were also reduction of Sulphate ions, THC, salinity and conductivity. Luffa cylindrica is an effective biosorbent for the removal of heavy metal ions; offering a cheap option for primary treatment of produced water.
