The new depth filter medium, BecoPad recovers precious metal catalysts from reaction products without losses, so they can be returned to the process. Because very fine catalyst components are also removed, the very high purity of the mineral-free BecoPad and the strong reduction in extractable ions ensure maximum purity of the end product. The filter medium also offers high chemical and mechanical resistance when filtering aggressive solutions. This depth filter has virtually no ash content, so spent catalyst can be fully recovered after ashing. — E. Begerow GmbH & Co., Langenlonsheim, Germany
