Paragraph starter

The review by Patel (2019) highlights the efficacy of fixed-bed column adsorption for removing contaminants such as chromium from wastewater. A critical aspect for the successful design and operation of such systems is the analysis of the breakthrough curve, which predicts the point at which the adsorbent becomes saturated and contaminant breakthrough occurs, necessitating regeneration or replacement.
