Abstract

Multiple water purifier modules are stacked in a rack having manifolds for each of the various water filtration functions: feed, concentrate, and filtrate. Each module connects to the rack by a quick connect for each of the filtration tubes. The quick connects are of the self-sealing type. A handle on the end of the module away from the rack has a lever for causing the quick connects to release the module from the rack while the system remains in operation. The, module can then be totally removed from the rack for testing, service, or replacement while the overall system remains in operation. Each module contains complete filtration media. The water is passed into the feed tubes under pressure where it passes into an elongated cavity filled with elongated hollow fibers. Filtrate, such as purer water, passes through the walls of the hollow fibers to an outlet, while concentrate, which is fluid with a high percent of impurities, flows from the cavity into concentrate tubes to another outlet for disposal. The tubes and concentrate tubes are small diameter tubes with small holes spaced along their lengths. The tubes lie at opposite sides of the cavity, rather than at opposite ends, and the tubes are surrounded by the fibers that are tightly packed together and that are tightly packed around the tubes, to control the flow rate of feed fluid between them.
