Two types of zeolite were briefly used to treat wastewater from a refinery i.e. one was natural zeolite of clinoptilolite type received from Slovakia and the other manufactured synthetic zeolite purchased abroad. Pollutants examined in this study for above adsorbent efficiencies were - petroleum hydrocarbons, heavy metals, sulfur and ammonia compounds. The removal efficiencies of these materials were compared to each other and with the two types of conventional activated carbons. The results showed that the zeolite performed some better properties in removal of ammonia compounds than activated carbons. It was concluded that the zeolite could be the best choice for some specific water treatment, however not for heavily contaminated refinery wastewater.
