  • Systems, Apparatus, and Methods for a Water Purification System
    Publication number: 20130126430
    Abstract: A water purification system comprising a cross-flow filter is arranged to permit recirculation of the retentate or reject water from the retentate outlet of the filter to the inlet of the filter. A first pump is configured to pump source water into the feed water path of the filter, and to raise the fluid pressure in the feed water path and recirculation path. A second pump is configured to recirculate water from the retentate outlet of the filter to the inlet of the filter at a flow rate substantially higher than the flow rate of water generated by the first pump. A drain path connected to the recirculation path or feed water path may include a flow restrictor to permit removal of highly concentrated reject water while maintaining a minimum fluid pressure within the recirculation flowpath.
