Chlorine removal with activated carbon using bubble column

Abstract EN

Bubble column slurry reactor was used for the measurements of gas adsorption and ion-exchange in this work.

Adsorption of chorine (dissolved in water) on activated carbon was carried out in the same reactor.

The effect of gas flow rates Ug 0.016 m s–1-0.027 m s–1 which covers the boundaries of the following four regimes : bubbly flow, first transition, second transition, and coalesced bubble and solid concentrations were investigated.

In addition of studying the pH which gives an indication for Hypochlorous Acid HOCl, the most active sanitizer form of Free Chlorine.

These design guidelines provide a good starting point for system of removing chlorine from water at activated carbon concentration 20 gm / L, gas velocity 0.023 m / s and contact period of time more 17 minutes.
