Abstract
Embodiments of the invention provide a membrane module including a first plurality of fibers capable of filtering fluids that are helically wound in layers creating a mono helix. Fluids to be treated can flow radially with respect to a longitudinal axis of the mono helix or parallel to the longitudinal axis of the mono helix. The membrane module can further include a second plurality of fibers that are helically wound with the first plurality of fibers to create a dual helix. The second plurality of fibers can have different properties than the first plurality of fibers in order to achieve different filtering functionalities.
