Civil engineering (General) Zeolite is commonly used as an adsorbent to remove the pollutants in water, wastewater and leachate treatment through the adsorption and ion exchange mechanisms.

This study aims to review the adsorption and ion exchange mechanisms in water, wastewater and leachate treatment by using zeoliteas an adsorbent and/or ion-exchanger. The performance of the adsorption mechanism is affected by various parameters such as pH, adsorbent dose, contact time and initial concentration in the batch study. Many researchers found that Langmuir isotherm is the common adsorption isotherms found in zeolite, which is assumed to be monolayer adsorption. Many researchers also proved that the pseudo-second-order model is the common adsorption kinetics in zeolite to remove contaminants. However, the adsorption mechanism cannot be based on the simple fitting of the pseudo-second-order model, and further finding such as the intra-particles diffusion model need to be conducted. In the ion-exchange mechanism, the selectivity of ions is based on the charge density of the ions and the chemical composition of the zeolite. In the column study, flow rate and bed depth are the factors that would affect the removal efficiency of the pollutants in the experiment. The bibliometric analysis on the trends of zeolite application in water, wastewater and leachate treatment in the past 40 years (1980-2020) has also been conducted.
