Abstract

Systems and methods for separating components of a mixture are provided. The systems can include at least one section that defines a tortured path configured to provide some components in one direction along the section and other components in another direction along the section. Methods can provide for the separation of bubbles within a liquid matrix, liquid separation, liquid/solid separation, and/or solids separation.
