Abstract:
A low-noise vibration-reduction water purifier comprises: a shell body; a pump assembly, disposed vertically in the shell body, with its water input tube connected to a water pipe of faucet water, and with its water output tube connected to a filtering core L; a sound silencing cotton sleeve, sleeved around the water input tube and the water output tube; and a sound silencing cotton layer disposed between outer perimeter of the pump assembly and the shell body. The low-noise vibration-reduction water purifier is novel in design, simple in construction, capable of achieving vibration and noise reduction effectively, while adding comfort in operation. In addition, the low-noise vibration-reduction water purifier installation method can be used to realize installation in a simple manner, to facilitate convenient operation.
Abstract:
A robotic pool cleaner includes a housing with an interior chamber. A filter within the interior chamber filters water drawn through a water inlet provided in a bottom portion of the housing. Filtered water is discharged through a discharge port provided in a upper portion of the housing. Rotatably-mounted supports attached to the housing support and guide the cleaner on the pool surface. An electric motor mounted in the chamber is configured to move the cleaner on a pool surface. A pool cleaner controller electrically connected to the electric motor controls movement of the cleaner and receives communication signals transmitted by a remote power supply over a two-wire electric cable having first and second conductors. The pool cleaner controller is configured to provide uninterrupted electric power to the electric motor while the pool cleaner controller also receives pulsed communication signal from the remote power supply over the two-wire cable.
Abstract:
A gravity driven water filter having: a housing with at least one upwardly extending sidewall that extend upwardly from a bottom of the housing and define an interior volume of the housing; a filter media retention screen covering treated water outlets on a bottom of the housing; and a lid closing a top of the housing and enclosing the interior volume of the housing where the lid includes a plurality of water inlet holes, an upwardly extending vent stack, and finger actuated tabular members radially extending from the vent stack and engaged with the vent stack and a top surface of the lid to permit a rotational force to be applied to the housing.
Abstract:
Devices, modules, systems, and methods for the desalination of water provided. The devices, modules, systems can include a desalination member separating a concentrated fluid chamber from a dilute fluid chamber. The desalination member can comprise one or more pores extending through the desalination member to fluidly connect concentrated fluid chamber and the dilute fluid chamber, and one or more electrodes configured to generate an electric field gradient in proximity to the opening of the one or more pores in the desalination member. Under an applied bias and in the presence of a pressure driven flow of saltwater into the concentrated fluid chamber, the electric field gradient can preferentially direct ions in saltwater away from the opening of the one or more pores in the desalination member, while desalted water can flow through the pores into dilute fluid chamber.
Abstract:
The present invention relates to a water filter device comprising a filter head with filter head components, a replaceable filter candle with filter candle components, and an encoding structure which is formed between a filter head component and a filter candle component. Said water filter device is distinguished, in a first embodiment, in that an encoding structure is formed with axial orientation on an end face of the filter candle and/or on an element which is associated with such an end face of the filter candle. In a second embodiment, said water filter device is distinguished in that an encoding structure is formed separately from a fixing structure.
Abstract:
The invention provides systems and methods for purification of fluids such as water and air. The fluids are passed through a filter comprising chlorhexidine citrate (CXC), wherein either in the same filter or downstream from it a sorbing mixture of porous calcium phosphate, calcium carbonate and activated carbon is also provided. The invention enables rapid, economical fluid purification without byproducts. The materials can be regenerated for reuse, and the invention can be used for either high volume applications or disposable single-use applications.
Abstract:

The microbial control system includes antimicrobial treatment media housed in a containment vessel. The treatment media can include any one or more of transition metals and transition metal oxides. The transition metal may be any of Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Y, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd, Hf, Ta, W, Re, Os, Ir, Pt, Au, Hg, Rf, Db, Sg, Bh, Hs, Mt, Uun, Uuu and Uub.
Abstract:
An integrated composite filter and a water purification system having the same are provided. The integrated composite filter includes: a shell defining a chamber therein, and defining a raw water inlet, a pretreated water outlet, a pretreated water inlet, a pure water outlet and a waste water outlet which are in communication with the chamber respectively; a pretreating filtering element disposed within the chamber; a filtering membrane disposed within the chamber. The pretreating filtering element and the filtering membrane are sequentially positioned between the raw water inlet and the pure water outlet as well as the waste water outlet, and the pretreating filtering element is positioned between the raw water inlet and the pretreated water outlet, and the filtering membrane is positioned between the pretreated water inlet and the pure water outlet as well as the waste water outlet.
Abstract:
A drainless reverse osmosis (RO) water purification system provides relatively pure water for on-demand dispensing, while recycling brine to a domestic hot water system. The drainless purification system includes a pre-filter catalyst cartridge for removing chlorine-based contaminants from a tap water supply upstream from an RO membrane. The catalyst is regularly refreshed by a high through-flow of water to a conventional cold water dispense faucet, thereby significantly prolonging the service life of the RO membrane. The RO membrane is incorporated into a multi-cartridge unit adapted for facilitated slide-out removal and replacement as needed. A control valve recycles brine from the RO membrane to the hot water system during pure water production, and recirculates tap water through the RO membrane when a pure water reservoir is substantially filled. The multi-cartridge unit may further include an air filtration system for providing a flow of filtered air.
