Claim 10:
11. A system according to claim 8, wherein the filtering arrangement comprises:
a cellulose fiber mixing vessel arranged for receiving a filter building oil and a cellulose fiber powder;
a cellulose fiber source connected to the cellulose fiber mixing vessel; and
a carrier layer connected to the cellulose fiber mixing vessel and arranged such that the filter building oil and the cellulose fiber powder in the cellulose fiber mixing vessel can be circulated over the carrier layer to build a depth filter on the carrier layer,
wherein the filtering arrangement is configured to add the cellulose fiber powder from the cellulose fiber source to the cellulose fiber mixing vessel during the circulation until a filter cake of the depth filter is large enough to filter the mixture of the contaminated oil and the separation aid provided in the mixing tank.
