Water Treatment Patent

In-home water treatment system


A method and apparatus are provided for a water treatment system that includes both filtration and ultraviolet disinfection elements in a single unit. Various embodiments include a complete treatment system having replaceable filter elements or granular filter media and ultraviolet disinfection within a single vessel. A control valve controls flow through the system in filtering, backwashing, cleaning, and rinsing modes of operation. Other embodiments include couplings that may be adapted to new or existing treatment systems to provide ultraviolet disinfection to a vessel containing replaceable filter elements or granular filter media. The coupling is adapted to receive a control valve assembly that controls flow through the vessel in filtering, backwashing, cleaning, and rinsing modes of operation.

Water treatment system and method


A water treatment system provides treated or softened water to a point of use by removing a portion of any hardness-causing species contained in water from a point-of-entry coming from a water source, such as municipal water, well water, brackish water and water containing foulants. The water treatment system typically treats the water containing at least some undesirable species before delivering the treated water to a point of use. The water treatment system has a controller for adjusting or regulating at least one operating parameter of the treatment system or a component of the water treatment system to optimize the operation and performance of the system or components of the system. A flow regulator regulates a waste stream flow to drain and can be operated to recirculate fluid through electrode or concentrating compartments of an electrochemical device and can opened and closed intermittently according to a predetermined schedule or based on an operating parameter of the water treatment system. The flow regulator can also be charged so that ionic species can be generated in the surrounding fluid, which, in turn, can lower the pH of the surrounding fluid.

Water treatment apparatus

A water treatment apparatus in which the various components that constitute the apparatus (prefilters, osmotic membrane filters, pump, et cetera) are contained in an enclosure. The enclosure includes a body provided with compartments that accommodate the components of the apparatus and at least one cap provided internally with channels for conveying the water in output from one compartment to the next. In this manner, the components of the apparatus are mutually connected without the need to use piping.
