The effect of cross-flow filtration of liquids relies on the continuous and controlled circulation of fluids in linear channels. The flow rate is of crucial importance to the economy of the process. TAMI Industries is investigating the use of so-called additive processes to produce ceramic supports with geometric structures that cannot be produced using traditional technologies. In comparison to conventional geometries, it is possible to increase the permeate output without increasing the energy consumption or correspondingly reducing the energy consumption at the same permeate output.
