Abstract:
Sanitizing photocatalytic reactor suitable for air liquid or liquid fluids, essentially comprising a reaction region containing a photocatalyst selected from the nanotechnological materials of the natural light photocatalyst type, supported on an inert support or else mixed with plastic material, and an illumination region having white color LED lights, where said reaction region comprises one or more channels through which said fluids to be sanitized flow.
Abstract:
A liquid treatment cartridge includes at least one liquid treatment part (19) and a housing encapsulating the liquid treatment part (19). The housing includes a liquid-pervious housing component (20) and a main housing component (21). The main housing component (21) is defined by a wall, impervious to liquid, of which a portion forms a side wall section (26) of the housing and a portion forms a base wall section (27) of the housing. The main housing component (21) has a mouth (28) at an opposite end to the base wall section (27). At least one aperture (30) is formed in the wall of the main housing component (21), in which aperture (30) a liquid-pervious window is formed. The liquid-pervious housing component (20) is joined to the main housing component (21) to close the mouth (28) and encapsulate the liquid treatment part (19). The main housing component (21) is a thermoformed component.
Abstract:
A pressure vessel having an outer shell and a flexible inner liner. The outer shell and inner liner are configured so that the water passing through the water treatment system engages the inner liner, and not the outer shell. The inner liner is blow molded from a material that does not leach undesirable substances into the water flowing through the water treatment systems. The inner liner may include a receptacle portion to house one or more water treatment components. The receptacle portion may be flexible under the anticipated range of internal pressures. The receptacle portion may be disposed in the outer shell with the outer shell concealing expansion/contraction of the inner liner and providing the pressure vessel dimensional stability. The inner liner may include a rigid neck portion mounted to the outer shell. The outer shell and/or inner liner may include internal ribs configured to maintain spacing therebetween.
Abstract:
The present invention relates to the purification and dispensing of pure and bacteria-free water. Hereto, a capsule (15) is described with a membrane configuration that can be provided in a device for purifying water (3). Described is also a device in which the capsule fits, and that carries out a pre-filtration of the water (10, 11).
Abstract:
An ion-exchange and ultrafiltration filter system having an exterior housing having an inlet and an outlet with an ultrafiltration membrane provided within the housing along a central axis about a central portion of the housing with an ion-exchange membrane provided within the housing between the ultrafiltration membrane and the housing. The ion-exchange and ultrafiltration filter system being capable of being configured so as to provide two-step filtration in a plurality of modes, either ion-exchange to ultrafiltration, or ultrafiltration to ion-exchange.
Abstract:
A water purification system includes one or more UV light sources that produce germicidal UV light and provide the UV light to a given amount of fluid contained in a chamber as a batch or as flowing through the chamber. An inner surface of the chamber, that may be reflective, is coated with a thin plastic film, such as polypropylene, that is highly transmissive to UV germicidal light. The thin plastic film separates the inner surface from the fluid, and the UV light passes through the thin plastic film to reach the fluid that is being purified in the chamber. The thin plastic film may be melted at relatively low temperatures to provide heat sealing of the surface to produce the chamber. Alternatively, the thin plastic film may be readily shaped as a bag or pipe that contains or directs fluid flow.
Abstract:
A water injection process plant includes a catalytic deoxygenation unit (50) located subsea that makes use of a reducing agent (60) sent from topsides in liquid form. The catalyst is preferably a palladium catalyst or its equivalent. The reducing agent is an oxygen scavenger such as but not limited to hydrazine, carbohydrazide, sodium erythorbate, methyl ethyl ketoxime ("MEKO"), hydroquinone, diethylhydroxylamine ("DEHA"), formic acid (methanoic acid). A chemical umbilical (55) can be used to deliver the reducing agent to a mixer (51) located upstream of the deoxygenation unit, where the agent is mixed with seawater containing oxygen.
Abstract:
The present invention relates to filter capsules for showers and sinks used in surgical settings, cleam rooms and other contaminant-sensitive settings having modified outlets for improved splash control. A recessed outlet improves prevention of contaminant dispersal by recessing the outlet away from contact points and potential contaminant source. A filter capsule comprises: a capsule wall, a filter cartridge, a capsule top cap having an inlet with an axis offset from a filter capsule longitudinal axis, and a recessed outlet having a recessed outlet wall extending inwardly into a filter cartridge core.
Abstract:
Die Erfindung betrifft ein Filtersystem zur Reinigung eines Fluids in einem Whirlpool und/oder einen Swimspa mit einem Filterelement aus einem Faservlies, das im Wesentlichen rotationssymmetrisch ausgebildet ist, wobei ein Filtergehäuse zur Aufnahme des Filterelements, wobei das Filtergehäuse einen, einen Aufnahmeraum für das Filterelement begrenzenden Gehäusemantel mit einer Vielzahl von Öffnungen und einen in dem Aufnahmeraum des Gehäusemantels angeordneten Rohrabschnitt mit zumindest einer Durchtrittsöffnung für das Fluid aufweist und wobei das durch den Gehäusemantel eintretende Fluid das Filterelement durchströmt und anschließend über den Rohrabschnitt abgeführt wird.
Abstract:
A filter head (1) for fitting to a water filter (20) is provided. The filter head (1) has a filter connector (5) for enabling the filter head (1) to be connected to the filter (20). A water inlet (10) allows water to enter the filter head (1) from an external water supply. A water inlet passage (11) passes water entering the water inlet (10) to the filter (20) connected in use to the filter connector (5). A first water outlet (15) allows water that has passed through the filter (20) to exit the filter head (1) through the first water outlet (15). A second water outlet (16) allows water that has passed through the filter (20) to exit the filter head (1) through the second water outlet (16).
