Abstract
This study is to evaluate the role of clays and zeolites on the coagulation and ion exchange treatment of municipal wastewater. Clay minerals used included kaolinite, montmorillonite, halloysite, and bentonite. Zeolites used included mordenite, faujasite, silicalite, and synthetic zeolite-A. Clays and zeolites proved to be rather ineffective in decreasing the turbidity. Clays and zeolites showed a limited succes in removing Na from the wastewater. Most zeolites appeared to be quite effective in removing Ca and Mg from the wastewater with about 100% removal efficiency for Ca at a dosage of 2.0 g/1. The TOC removal efficiency of primary effluent ranged from 14 to 34% at a dosage of 1.0 g/1. Bentonite and silicalite were most effective in removing organic carbon from primary effluent. © 1991, Taylor & Francis Group, LLC. All rights reserved.
