Abstract

Embodiments, presented herein are directed to a filtration system including an outer pipe, an inner pipe and a stirrer. The outer pipe is configured to receive a working fluid from a filter inlet. The outer pipe includes a venturi neck and an outer channel. The venturi neck is located downstream of the filter inlet. The outlet channel is located downstream of the venturi neck, wherein the outlet channel is configured to provide an outlet for a first type of impurity. The inner pipe is co-axially positioned with the outer pipe, wherein the inner pipe is configured to receive a second type of impurity. The stirrer is positioned inside the outer pipe, wherein the stirrer rotates with the inner pipe to substantially separate at least the first and the second types of impurities from the working fluid.
