Performance and modeling of zeolite adsorption for ammonia nitrogen removal

Abstract

This study was conducted to investigate the adsorption characteristics of synthetic zeolite for removal in fermentation permeates and to establish a mathematical model for system design. Zeolite with a size of 1.7–2.3 mm, cation exchange capacity 130 meq/100 g-zeolite, gravity 1.7, and micropore surface (product of TOSO Company) was used in this study. This experiment was focused on the following research points: (1) effect of pH on adsorption and (2) simulation on space velocity or line velocity as design and operational parameters by adsorption isotherm.
