The invention also relates to a head of a water- treatment device for use with a water-treatment cartridge (3). In addition, the invention relates to a water-treatment device comprising a head and a water-treatment cartridge (3).

A water ejecting apparatus includes a case and a water ejection unit coupled to one side of the case. The water ejection unit includes a rotator seated inside at a front of the case, a first lifting cover coupled to one side of the rotator and allowing a lifting gear extending in an up-down direction to be fixed thereto, a second lifting cover movably accommodated inside the first lifting cover, a lifting motor coupled to the second lifting cover and configured to interwork with the lifting motor, and a water ejection nozzle installed at a lower end of the second lifting cover and configured to eject water. A water ejection pipe having one end connected to the water ejection nozzle and the other end extending to an inside of the case is disposed in a lower space of the lifting motor and the gear module.

A medicament preparation system includes a disposable cartridge with a flow path. Various sensors may be placed on the cartridge to measure qualities of the fluid flowing through the flow path. The sensors are placed in precise locations using various approaches that make manufacturing of the cartridge efficient and repeatable. A drain line that is susceptible to fouling may be preattached and various approaches are used to remove or reduce the fouling. An elastomeric contact can also be present in the medical preparation system and used in a conductivity measurement subsystem.

A water purification apparatus (300) capable of being cleaned at a point of care, and methods for cleaning the water purification apparatus (300) at the point of care. The water purification apparatus (300) and the methods provide an efficient use of a heater (302) for heat disinfection the water purification apparatus (300), e.g. by recirculating heated fluid to further heat the fluid. Several different cleaning programs are provided that may be utilized for cleaning different parts of the water purification apparatus (300).

A marine water treatment dock box system is provided. The marine water treatment dock box system securely houses a water softener, a deionizer, a high-pressure washer and a selective control system for diverting water for cleaning a docked vessel, for onboard use by the vessel, and/or for high-quality potable water production. The above-mentioned components are operatively associated to outlets disposed along the exterior of the dock box body, maintaining the security and protection of the components. The water softener may be fluidly connected to an inlet to the dock box and a three-way valve for selectively controlling the softened water to one of the following: (1) a high-pressure pump for washing a vessel; (2) to the deionizing tanks for dissolving solids for a spot-free rinse; and or (3) to an outlet to fill onboard fresh water tanks.

In an embodiment, a sustainability resource management system includes a sustainability status unit configured to generate a virtual display including one or more instances of a predicted sustainability status associated with a utilization of at least one resource and an enticement unit configured to activate one or more appraisals associated with the resource utilization.

A pure water production system includes a filter unit, a clear water storage tank, an ultraviolet light irradiation unit, and an ion exchange resin unit. The filter unit filters water. The clear water storage tank stores water filtered by the filtration unit. The ultraviolet light irradiation unit irradiates ultraviolet light to water delivered from the clear water storage tank. The ion exchange resin unit produces pure water from water delivered from the ultraviolet light irradiation unit. The ultraviolet light irradiation unit includes an ultraviolet fluorescent lamp, and an outer tube configured to allow the water to flow through surroundings of the ultraviolet fluorescent lamp. The outer tube includes an inflow port through which the water flows in, and an outflow port through which the water irradiated with ultraviolet light from the ultraviolet fluorescent lamp flows out.

A water dispenser which is connected to a pure water source and used for dispensing pure water includes: an arm mounting unit; a water dispensing gun including a nozzle for discharging pure water; a holding unit for holding the water dispensing gun; and at least two arms connecting the holding unit to the arm mounting unit. The at least two arms constitute a parallel link mechanism in which a trajectory of each arm when the at least two arms move is within the same vertical plane.

A method for treating wastewater involves electrolyzing a stream of seawater and wastewater mix within one or more electrolytic cells mounted outside a batch tank. The electrolyzed stream is piped to a quelling chamber which is mounted above the batch tank. A diluted polymer solution is injected at upstream of an in-line mixer piping into the quelling chamber substantially concurrently with the electrolyzed stream. The polymer solution and the electrolyzed stream are dispersed as a fine shower over residual seawater and wastewater in the batch tank. The polymer solution facilitates flocculation of the suspended solid particles and creates a distinct buoyant layer of flocculated solid particles attached with micro bubbles. A substantially clarified effluent is separated from the flocculated layer and neutralized prior to discharge. The flocculated layer is pumped from the batch tank to a dewatering system where entrained solids are compacted to a desired level. A centrate generated during the solids/sludge dewatering step is recirculated to the batch tank prior to addition of seawater during a subsequent treatment cycle as a supplement to the seawater.

A system includes a filter device that has, in serial flow order, an adsorbent bed, a biocide filter, and a particle filter. The adsorbent bed includes adsorbent media that is configured to remove organic compounds from feed water that are capable of forming an adherent layer on a porous surface of a sublimator, and the biocide filter contains a halogen-release material.
