Abstract:
A method for concentrating a mixture of at least one fluid component and at least one solid component, the method comprising:a) providing a flexible, longitudinally extending hose, the hose having an inlet, an outlet, and a wall, the wall having a fluid permeable portion;b) introducing the mixture into the inlet;c) compressing the hose at a portion thereof at or upstream of the fluid permeable portion;d) longitudinally moving the compressing towards the outlet, where the moving induces peristaltic flow of the mixture from the inlet to the outlet, and where the moving forces at least one of the at least one fluid component to permeate the wall portion, such that the mixture is concentrated as the mixture flows from the inlet to the outlet; ande) removing the concentrated mixture from the outlet.
