Activated charcoal/ultrafiltration process has been used for molasses decolouration.

Activated charcoal is an efficient decolouration agent for beet molasses.

Process optimisation is discussed in terms of the charcoal decolouration capacity.

Good regeneration of exhausted charcoal is obtained using NaOH solutions.

The loss of decolouration capacity for NPAC after regeneration has been evaluated.
