Abstract: A method including the steps of moving fluid through an inlet into a vessel, the vessel being at atmospheric pressure and having at least one side wall and a bottom wall forming an internal chamber within the vessel. The method further includes moving the fluid into and through a filtration unit utilizing a downstream pump, the filtration unit creating a flux of less than or equal to about 0.05 gallons per minute per square foot (GPM/ft2), and moving the fluid processed by the filtration unit to an outlet and out of the vessel.

Abstract: A shoe comprising a sole. The sole includes a midsole including multiple midsole portions. A first midsole portion is an inner portion of a first midsole material. A second, midsole portion of a second midsole material circumscribes the first midsole portion, and a third midsole portion formed of a third midsole material circumscribes the second midsole portion. The second midsole portion has a greater durometer hardness than the first midsole portion. The third midsole portion has a different durometer hardness than the second midsole portion. The second midsole portion is of a different color than each of the first midsole portion and the third midsole portion.

Abstract: A particle separation system may comprise a vessel having at least one side wall and a bottom wall forming an internal chamber within the vessel, a filtration unit positioned within the vessel and including a first filtration pack including a first plurality of filter elements, an inlet for moving pre-separated fluid into the vessel, and an outlet in fluid communication with the filtration pack for moving processed fluid out of the vessel, a rate of pre-separated fluid flow into the vessel and a rate of processed fluid flow out of the vessel each being between about 10 and about 1000 gallons per minute (GPM) and a flux within the filtration unit is less than or equal to about 0.05 gallons per minute per square foot (GPM/ft2).
