Abstract

The irregularities on the support surface are first sealed by a temporary coating, then the membrane material is applied in a thin uniform layer in the liquid state (molten, solution, suspension or emulsion). After setting, the temporary coating is removed (pref. by soln.) to regenerate the support's permeability. The temporary coating may be applied in emulsion, suspension, solution or molten state. The support is pref. a metal gauze. Uses are in (reverse) osmosis, (electro) dialysis, (ultra) filtration and the like.
