Abstract: Sugar syrups, or waste molasses solutions are purified by being passed through one or more than one ion-exchanger or activated carbon, e.g. animal charcoal, moving in counter-current; fresh ion-exchanger or activated carbon being introduced periodically and used ion-exchanger or activated carbon being continuously discharged, during the purifying operation. The arrangement of two treatment vessels is shown in Figs. 4 and 6.ALSO: Liquid is contacted with solid in countercurrent in vessel 1 entering by inlet 1 and leaving by outlet 3. Fresh solid is introduced from hopper 7 when the flow of liquid is stopped and liquid in the vessel drained through outlet 4. The solid may be activated carbon or sand particles. Thus sand may be employed to filter out copper hydroxide particles from copper sulphate solution, the sand being subsequently freed from deposited copper hydroxide by contact with sulphuric acid.
