A hyperfiltration system (10) and method for treating water including: a vessel (20) having a feed inlet (22), a permeate outlet (24), and a concentrate outlet (26); at least one spiral wound membrane element (28) located within the vessel (20); a pump (30) having a low pressure side (32) in fluid communication with a source of feed water (40) through a junction point (42) and a high pressure side (34) in fluid communication with the feed inlet (22); a permeate valve (50) connected to the permeate outlet (24) and adapted to selectively direct permeate flow between a treated water outlet (52) and the junction point (42); a flow path (60) between the concentrate outlet (26) and a discharge (62); and a flow restrictor (64) located along the flow path (60) and adapted to vary resistance to concentrate flow between a high and low value.

A filtration cooler system includes a cooler reservoir having a reservoir receiving portion, a lid coupled with the cooler reservoir, a drip tray, a filter bucket, and a filter. The drip tray is received by the cooler reservoir such that the drip tray is disposed over the reservoir receiving portion. The filter bucket has a filter receiving portion operable to receive water. The filter bucket is received by the drip tray when the drip tray is disposed over the reservoir receiving portion. The filter is received in the filter bucket. The filter filters the water in the filter bucket such that the water passes from the filter bucket into the reservoir receiving portion. The drip tray and the filter bucket can be nested such that the drip tray and the filter bucket fit within the reservoir receiving portion when the lid is closed over the cooler reservoir.

A water filtration system that includes a filter manifold having a rotatable cover is provided. A filter cartridge is provided that includes a sump having a filter head integrally secured to a first end and cap releasably secured to a second end. A locking mechanism extending from the cover locks into the filter manifold to position the cartridge in an “in-use” state. The filter cartridge further includes two offset cylindrical inlet and outlet members protruding from the filter head that are designed to engage corresponding inlet and outlets of the filter manifold through a horizontal engagement mechanism. A check valve is positioned within the filter manifold adjacent the inlet of the filter cartridge to control fluid flow through the water filtration system. The filter cartridge head includes fins upwardly extending therefrom that are configured to engage corresponding slots formed in a plurality of corrugated channels of the filter manifold.

It is described a point-of-use (POU) water purifier (10), comprising a housing (11) the inner space of which is divided by a bundle (16) of hollow fibers into an inlet compartment (14) in fluid communication with an opening (12) for connection of the purifier to the waterworks, and an outlet compartment (15) in fluid communication with the outlet (13) of purified water; the hollow fibers have an inner diameter between 150 and 250 μ.Math.τ.Math. and a wall thickness between 30 and 50 μ.Math.τ.Math., and have pores of different size and shape on the inner and outer surface of the fiber.

A water treatment system having a base assembly and a treatment assembly. The treatment assembly of the system may be configured to filter particulates from water. The base assembly may include a UV reactor operable to disinfect water for consumption.

Disclosed is an automated smart water purification and dispensing apparatus for providing purified water to a plurality of users. The water dispensed by the automated smart water purification and dispensing apparatus employs an ION purification means and an Ozone purification means for the incoming water from the water supply. The automated smart water purification and dispensing apparatus includes a display means for providing visual information and an audio output means for providing audio information to users. The subscribers of a water-dispensing scheme proposed by a central computerized controller can receive water using a storage container having an optical code that can be read using an RFID reader of the automated smart water purification and dispensing apparatus. The central computerized controller communicates with a central server in real time for transferring information about the subscribers and for controlling water dispensing accounts associated with each of the subscribers.

A water dispenser includes a filter unit filtering raw water supplied from a raw water supply unit to produce purified water, a cold water tank assembly cooling purified water to produce cold water, a refrigerating cycle device maintaining cooling water filled in a cooling water accommodation unit at a low temperature, a cooling water flow channel supplying water to the cooling water accommodation unit, a flow rate sensor measuring a flow rate of water supplied to the cooling water accommodation unit, a stirrer to stir the cooling water filled in the cooling water accommodation unit, and a controller determining whether cooling water has been filled up to a reference water level on the basis of a rotation speed of the stirrer per unit time.

A water filtration housing containing a pressure vessel configured to receive a water filter cartridge; a ring enclosure attachable to an open, top end of the housing enclosure; an interface tower including a user interface; a lid assembly removably attachable to the ring enclosure, the lid assembly including (i) a pressure cap and gasket for maintaining a given pressure in said pressure vessel and (ii) a rotatable lever for disengaging the pressure cap from the pressure vessel thereby releasing pressure therein. A mating system between the lid assembly and ring enclosure prevents the lid assembly from being attached to the ring enclosure in a misaligned fashion. RFID technology may be used for identifying the water filter cartridge installed therein and wireless communication technology (e.g., Wi-Fi) to transmit collected system data (e.g., water usage) to a central location for analysis such that the customer is provided with, for example, operational suggestions.

A beverage extracting device according to an embodiment of the present invention may comprise: an extracting part including an installing space in which a beverage capsule is installed; an opening and closing part connected to the extracting part, for opening or sealing the installing space; a link part connected to at least one from among the extracting part and the opening and closing part; and a perforating part for moving reciprocally according to the movement of the link part so as to perforate the beverage capsule.

A liquid treatment device includes a base with a power source, a UV-LED module for providing UV-B or UV-C light to liquid, an LED for providing visible light, and a processor for selectively powering the UV-LED module and the LED, and having a UV transmissive material above the UV-LED module for allowing the UV-B or UV-C band light from the UV-LED module to be transmitted from the base housing, and a liquid storage housing removably coupled to the base housing with a storage portion configured to hold liquid and having a bottom portion comprising a UV transmissive material for allowing the UV-B or UV-C band light from the UV-LED module to be transmitted into the liquid, and an output coupled for restricting outflow of the liquid from the storage portion.
