Abstract
The aim of the current study is to assess iron and manganese removal from water used for public supply through adsorptive filtration based on natural zeolites that were chemically prepared for metal removal purposes. The research was conducted at bench scale by using water samples from two water sources in Parana State. Full cycle studies were carried out; according to them, filtration was conducted, in separate, under four filter bed conditions, namely: sand, anthracite coal, zeolite without previous chlorine application and zeolite with previous chlorine application. The zeolite filtration test without previous chlorine application recorded high meaniron and manganese removal values, - 100% and 87.96%, respectively. Based on the filtration results, the zeolite filter without previous chlorine application was the best filter media among the tested beds, under the herein proposed conditions.
