  • Regeneration / Actived Carbon - Lenntech

    Activated carbon is an expensive product. In most of the cases the cost of replacing the saturated carbon would be prohibitive. It should therefore be regenerated, and four methods have been developed for this purpose Steam regeneration; This method is restricted to regenerating carbon which has only retained a few very volatile products.

  • A Look at Activated Carbon Thermal Regeneration

    Regeneration, often referred to as reactivation, is a method of thermally processing the activated carbon to destroy the adsorbed components contained on its surface. In regeneration, the adsorbed components are almost completely removed, yielding a regenerated carbon that can again function as an adsorbent.
