Problems solved by technology

A typical water filter utilizes pumps, valves and timers, which is complex and results in a more expensive manufactured water filter
As such, such water filters are often too costly for use in low-income areas

Embodiment Construction

[0119] refer to figure 1 , in the first configuration of the present invention, the water filter 10 includes a filter module 20 , a pressure chamber 30 and a pumping module 40 . The filter module 20 includes a housing 22 and hollow membrane fibers 24 (ie filter elements). Hollow fibers 24 are sealed within housing 22 by known means. In the illustrated embodiment, a water filter 10 is placed in the water 1 to be filtered. The untreated water 1 passes through a prefilter (such as a mesh strainer 12 ), and then is pumped into the filtration module 20 , especially the core of the hollow fiber 24 , by means of the pumping module 40 . The pumping module 40 in the illustrated embodiment is a user-operated pump comprising a cylindrical housing 42 , a piston seal assembly 44 , a piston rod 46 and a handle 48 . The flow is facilitated by pushing the handle 48 up and down so that the water to be filtered 1 enters the fluid chamber 18 via the first valve 14 (such as a suction valve) an...

Abstract

A fluid filter includes a filtration element; a supply conduit that is positioned to supply fluid to be filtered into the filtration element; a delivery conduit that is positioned to received filteredfluid from the filtration element; a pressure chamber which is fluidly continuous with the delivery conduit; and a filtered fluid outlet in fluid communication with the pressure chamber, the filteredfluid outlet including a flow limiter that restricts the flow of filtered fluid. When the flow limiter is operated, filtered fluid is caused to flow back from the pressure chamber to back flush the filtration element. The flow limiter can be actuatable manually or automatically.

Description

technical field [0001] The present invention relates to fluid filters, and more particularly to a water filter that includes a flow restrictor that can be manually or automatically operated and configured to allow backwashing of the water filter. The invention also relates to a method of operating the water filter. Background technique [0002] The present invention generally relates to a water filter for making filtered water safe to drink. The following discussion of the invention is in the context of a specific use case, but the invention can be applied to any water filter where backwash functionality is desired. [0003] The present invention uses known water purification methods, for example using a filtration module, which may comprise a hollow fiber membrane module with hollow fibers. The hollow fibers of the filtration modules allow water to pass through the microscopic pores in their walls, but prevent pathogens and other particles from passing through. For examp...
