Each vessel should allow a minimum of 3 minutes of contact time between the adsorbent medium and the wastewater. For those persons with a background in granular activated carbon treatment, the recommended contact time is equivalent to an Hourly Space Velocity (H.S.V.) of 5.5, which will be relatively high in their experience. H.S.V. is defined as the flow rate equivalent to the number of vessel volumes per hour.
