Abstract: Filtration technology based on a three stage process where a ceramic foam filter is operated in cake mode in the first stage; grain refiner added in a second chamber and a further filtration means is used in the third stage to remove oxide inclusions or agglomerates originating from the grain refiner addition has been developed along two directions. In one case, the XC Filter uses a small deep bed filter (DBF) in the third chamber, whereas in the second case a cyclone is employed. The most recent results with both are reported.
