Abstract
A filtration process and apparatus are provided wherein feed fluid to be filtered is introduced into a small gap between two rectangular plates. At least one of the plates supports a porous filtration membrane within the gap. During filtration, at least one of the plates is oscillated to effect a continuously changing gradient of gap width between opposing surfaces of the plate. A permeate is collected and a seal is provided to prevent admixture of the permeate with either feed fluid or retentate.
