Removal of Total Phosphorus from Domestic Wastewater with Clay-Zeolite Medium

Article Preview

Abstract:

Chemical adsorption of a clay-zeolite pellet medium is being investigated for the removal of total phosphorus from domestic wastewater. The effect of pellet composition, influent concentration, and contact time on the overall removal efficiency is being studied in a five-layer bench-scale model. Results showed that an equilibrium removal of 72% is achieved after a 3 hour contact time, supporting the Freundlich adsorption isotherm model based on the linearization of solute adsorption to equilibrium solvent concentration.
