摘要:
The present invention presents a filtration system with an integrated manifold valve. The filtration system employs only one pivotal component - the pivoting of the manifold. The manifold valve includes a dual aperture design for a two-fold alignment scheme with the ingress and egress lines of the fluid source. The invention is free of multi-component rotary valve with internal, rotatable parts, or an activation component, such as a handle, for initiating the rotary valve, allowing the user to rotate the rotational components thereof. The reduction in moveable components in this design reduces the likelihood of failure and increases the reliability of the filtration system.

Eine Wasserfiltereinrichtung mit einem rückspülbaren Wasserfilter (1), mit einem Gehäuse (2), einem in dem Gehäuse (2) angeordneten Siebfiltereinsatz (3), der das Gehäuse (2) in eine Einlasskammer (4) zur Aufnahme von ungefiltertem Wasser und eine Auslasskammer (5) zur Aufnahme von Filtrat unterteilt, und einer in der Einlasskammer (4) angeordneten Absaugvorrichtung (9) mit einem Absaugkopf (11), wobei der Absaugkopf (11) eine zum Siebfiltereinsatz gerichtete Rückspülöffnung (12) aufweist, wobei die Absaugvorrichtung (9) in einen Spülwasserkanal (10) mit einem Spülventil (8) mündet, welches im Rückspülbetrieb geöffnet ist, so dass Filtrat als Rückspülwasser durch eine Siebfilterfläche des Siebfiltereinsatzes (3) mit einer Fließgeschwindigkeit in die Absaugvorrichtung (9) strömt, ist dadurch gekennzeichnet, dass die Wasserfiltereinrichtung Mittel (13) umfasst zur Reduzierung der Fließgeschwindigkeit des Rückspülwassers an der Rückspülöffnung (12). Dadurch kann auch bei einem hohen Systemdruck ein Festsaugen der Filteroberfläche an der Absaugvorrichtung vermieden werden.

A fluid filter assembly (22) comprises an outer housing (24), a filter element (26) including a face (30), and a filter portion (28) extending from the face (30). The housing (24) has an inlet and an outlet. A spring (36) biases the face (30) against a housing structure (24) at the inlet. A pressure drop across the filter assembly (22) biases the filter element (26) against the spring force such that if the pressure drop exceeds the spring force, the filter element (26) can move to a bypass position. A hydraulic system (20) is also disclosed.

Provided are media cartridges that have adjustable bypasses, and systems and methods that use them. Aspects include an adjustable bypass filter cartridge where a treated stream and an adjusted non-treated stream combine prior to post-filtration and the percentage or ratio of treated the and the non-treated water is adjustable at the time of installation from the outside of the filter cartridge with a known or predictable level of bypass. Media cartridges comprise: an inlet in fluid communication with a feed chamber and an outlet in fluid communication with a mixing compartment; a media compartment containing a media; a bypass port in fluid communication with the feed chamber and the mixing compartment. Such cartridges can be adjusted to meet the needs of a wide variety of end uses.

A filtration system for an appliance includes a water source coupled with the appliance to provide an intake water flow. A filter unit is coupled with water source to receive the intake water flow and dispense a filtered water flow. An isolation valve is coupled between the water source and the filter unit and movable between a first position and a second position. A distribution valve is coupled with an ice maker and a water dispenser of the appliance. The distribution valve receives the filtered water flow when the isolation valve is in the first position, and the distribution valve receives the intake water flow via a bypass line when the isolation valve is in the second position. The isolation valve is configured to move to the second position upon expiration of the service life of the filter unit
摘要:
The present invention relates to a device for measuring the pollution index of a filtration membrane which includes: a raw water supply part supplying raw water to be measured; a first filtration membrane; a raw water supply line connecting the raw water supply part to the first filtration membrane; a first flow rate measuring part measuring the flow rate; a first path line connecting the first filtration membrane to the first flow rate measuring part; a second path line connected to the first path line in parallel; a second filtration membrane installed in the second path line and having a filtration characteristic different from the first filtration membrane; a first path selection valve installed in the first path line in parallel with respect to the second filtration membrane so that a first measuring path through which the raw water flows from the raw water supply part to the first flow rate measuring part passes through the first filtration membrane and a second measuring path through which the raw water flows from the raw water supply part to the first flow rate measuring part successively passes through the first filtration membrane and the second filtration membrane; and a pollution index measuring part measuring the pollution indexes of the first filtration membrane and the second filtration membrane on the basis of the flow rate measured by the first flow rate measuring part with respect to the first measuring path and the second measuring path.
