Design Specifications

The filtration system consists of a primary and secondary filter, with the backflushing process occurring in-line. Each filter contains bundles of hollow fibers designed to allow only water molecules to pass through the filter, filtering out anything larger than 0.1 microns (bacteria, cysts, protozoa). Valves located on the water input and water output assembly parts allow for control of water flow and operating mode. In standard operating mode, all valves are orientated horizontally. Water flows from the water input tubing, through the primary filter, and exits the system purified by the water output tubing.
