Abstract

ere has been a continuous concern about the discharge of metals and other trace chemicals to the aquatic environment, particularly to potable water sources in recent years. Although some of these metals are essential dietary elements, some of them are cumulative poisons when ingested. The high concentration of metals in the wastewater in generally caused by the discharge of industrial wastes to the sewage or by the infiltration of water that has passed through deposits of metal-bearing minerals. Metals release in wastewaters represents quite a serious environmental problem on account their well known toxic effect on natural life. In this work studies have been performed which demonstrate that iron ions may be retained by naturally occured zeolites. The experimental work performed on the natural zeolite, which is found abundant quantities in Turkey, showed that the ion exchange process is quite rapid and high quantities of iron ions are removed from the aqueous in a short period of time. The purpose of this study is to investigate the use of clinoptilolite, obtained from YalovaKaramürsel deposits, in the removal of iron ions from wastewaters. The experiments were run in a column system. Besides, the effects of feed flow rate and particule size on the ion exchange was also investigated.
