Peristaltic filtration hose apparatus and method

An apparatus for concentrating a mixture of at least one fluid and at least one solid, comprising:

• a) a flexible hose having a wall, an inlet, and an outlet, where the inlet is adapted to receive the mixture, and where at least a portion of the wall is permeable to the at least one fluid component;
• and
• b) compression means for compressing a hose cross-section, and longitudinally translating the compression in a direction from the inlet to the outlet,
• such that the compression means imparts peristaltic motion of the mixture in the hose, where the motion is from the inlet to the outlet, and induces the at least one fluid component of the mixture in the hose to permeate the wall portion.

An apparatus for concentrating a mixture of at least one fluid and at least one solid, comprising:

• a) a flexible hose having a wall, an inlet, and an outlet, where the inlet is adapted to receive the mixture, the wall having a fluid permeable portion;
• b) a surface for supporting the hose;
• c) a motor;
• and
• d) a roller having a roller axis, where the hose is disposed between the roller and surface, and the roller driven by the motor to:
• i) compress the hose between the roller and the surface;
• and
• ii) longitudinally translate the roller along the hose,
• such that the driven roller 1) imparts peristaltic motion of the mixture in the hose, where the motion is from the inlet to the outlet, and 2) induces the at least one fluid component of the mixture in the hose to permeate the wall.
