摘要

method of treating a fluid, particularly a beverage. A method for treating a fluid, especially a beverage, such as beer, wine or fruit juices, is provided by employing a particulate material in the form of a deposited layer having an upstream side and a downstream side, where a flow of Said fluid is directed through said layer deposited from the upstream side to the downstream side at a first temperature. In order to extend the period of time during which the particulate material may be used for treatment, it has been suggested to recondition said deposited layer and then resume treatment of said fluid, wherein said reconditioning comprises the steps of: deposited layer at a second temperature; and - cooling the deposited layer to a third temperature at an average cooling rate in the range up to about 20 198 c / min.
