1. A modular filtration system comprising:
- a filtration module including;
a chamber having a feed inlet and a filtrate outlet;
a plurality of hollow fiber membranes disposed in the chamber dividing the chamber into a feed side corresponding to an exterior of the plurality of hollow fiber membranes and in fluid communication with the feed inlet, and a filtrate side corresponding to an interior of the plurality of hollow fiber membranes and in fluid communication with the filtrate outlet;
a first header in fluid communication with the plurality of hollow fiber membranes; and
a first manifold including;
a manifold inlet in fluid communication with a source of feed liquid;
a first manifold outlet in fluid communication with the first header;
a first fluid passageway in fluid communication with the manifold inlet, a source of gas, the first manifold outlet, and the exterior of the plurality of hollow fiber membranes;
a second fluid passageway in fluid communication with the first header, the first fluid passageway, and the exterior of the plurality of hollow fiber membranes, the second fluid passageway configured to deliver gas to the feed side of the chamber; and
a second manifold outlet vertically displaced from the first manifold outlet and in fluid communication between the first fluid passageway and the second fluid passageway.
