Microfiltration 143 materials must drain away the permeate without any hydrodynamic resistance, and thus have a pore diameter of about 10 um or more. They are produced from sintered fine owdered materials including alumina, carbon, stainless steel and nickel. The tubular or multichannel geometries of modules(e.g. Fig. 5.2(a-c) are produced by extrusion of the Filtrate flows in conduits to downstream d of module Plugged passageways which isolate filtrate conduits from feed flow channels Opposite end has exactly ame appearance Passageways coated FEEDMicrofiltration 143 materials must drain away the permeate without any hydrodynamic resistance, and thus have a pore diameter of about 1Opm or more. They are produced from sintered fine powdered materials including alumina, carbon, stainless steel and nickel. The tubular or multichannel geometries of modules (e.g. Fig. 5.2 (a-c)) are produced by extrusion of the Filtrate flows in conduits to downstream end of module
