A novel filter media includes an array of raised features formed directly on the membrane surface, which create a feed channel. The predetermined configuration of features is dually optimized both for filtration in a first flow direction to maximize unobstructed fluid flow and prevent fouling. The same feature configuration is also optimized for enhancing/increasing turbulence and scouring of the membrane when the flow through the filter is reversed during a cleaning operation. The feature configuration can also be optimized to capture bubbles in reverse flow such that the captured bubbles can be oscillated to further scour the membrane and the features themselves (e.g., in their cavities, etc.).

Filter membrane with bi-directional flow enhancing features

A portable filtration system is described. The system may comprise: a mixing portion, comprising: a pump adaptor and a contaminant regulator. The pump adaptor may comprise: an upper plate, a lower plate, and a screen. The screen may axially extend between the upper and lower plates, wherein the upper plate, the lower plate, and the screen define a channel of a mixing chamber. The contaminant regulator may comprise a through-passage coupled to the upper plate, wherein the through-passage is in fluid communication with the mixing chamber.
