He has astonished engineers with some of his demonstrations: e.g., he pours a mixture of kerosene and water into a tube; the liquid comes out rapidly through the pores of two closed-end porcelain cylinders which are the outlets of the vessel; out of one comes pure water, out of the other, pure kerosene...
Walker tested his theory on fine porcelain membranes with pores as small as a 25,000th of an inch. It worked. By treating porcelain so that it could be wetted only by a specified liquid (e.g., coated with a special stearate, porcelain is wetted by kerosene but not by water), he found that up to a certain pressure the membrane was porous to that liquid but not to others...
Thus he eventually developed membranes that speedily separated not only water from oil but various liquid chemicals from water, water from city gas, water from compressed air. (His method separates only immiscible fluids and gases, does not work on emulsions or solutions...
