Pool filtration system and method

A pool filtration system for filtering pool water, comprising:

• a pump;
• a primary filter in fluid communication with the pump;
• and
• an auxiliary filter in fluid communication with the pump and the primary filter, the auxiliary filter comprising:
• a membrane filtration module, and
• a flow distribution manifold provided in the form of a manifold base and a manifold cover and further including an influent port in fluid communication with an influent flow opening and an effluent port in fluid communication with an effluent flow opening, the membrane filtration module fluidly coupling the influent flow opening and the effluent flow opening along a first flow path,
• the flow distribution manifold further including a bypass mechanism coupled between the manifold base and the manifold cover, the bypass mechanism including a first valve and a second valve that selectively fluidly couple the influent port and the effluent port along a second flow path to bypass the membrane filtration module.
