摘要： A device that comprises an outer component, an inner component and a filter module. The outer component includes a first hollow cylinder, and exterior ports in sidewalls of the first hollow cylinder. The inner component is positioned coaxially within the first hollow cylinder, and includes a second cylinder, and interior ports in the second cylinder, wherein the interior fluid ports are aligned parallel to the exterior ports. The filter module includes a hollow prism positioned coaxially within the outer component and surrounding the inner component, the hollow prism comprising at least four faces configured to retain filters.

摘要： The invention described herein is that of an outdoor drain filter useful for maintaining the operability of an outdoor drain despite the accumulation of debris that would otherwise obstruct the outdoor drain, resulting in flood prevention of surrounding areas. The outdoor drain filter of the present invention is placed above and around an existing outdoor drain or may be integral with a drain cover or drain reservoir. The outdoor drain filter comprises upper and side filtration means allowing the free flow of water therethrough. The outdoor drain filter further comprises a diverter comprising at least one air vent and at least one lateral pipe that defines a maximum water level to which water will accumulate around the outdoor drain before being diverted into the drain through the diverter. The outdoor drain filter may a manufactured unit or of modular construction.

摘要： A filtering unit includes a filtering component having inner and outer walls arranged around each other so as to define an inner space between the inner wall and the outer wall, a filtering mesh partitioning the inner space into a pre-filter chamber and a post-filter chamber, at least said pre-filter chamber being circumferentially compartmented in sectors, a divider arranged coaxially with the filtering component and having distinct distribution columns, and a rotary backwashing distributor having a shutter provided with a discharge opening, the rotary backwashing distributor being mounted to rotate so that said discharge opening is periodically and selectively put into communication with each distribution column, whereby each distribution column periodically and selectively establishes communication between the discharge opening and respective ones of the sectors. The rotary backwashing distributor is in direct contact with the divider.

摘要： Various examples are provided for smart water filter systems. In one example, a smart water filter system includes a solenoid valve (or other electrically operated valve) in a water supply line of a faucet, and a filter bank coupled to the water supply line. Activation of the valve can stop the flow of unfiltered water through the faucet while allowing the flow of filtered water through the faucet. In another example, a smart water filter system includes a three-port solenoid (or electrically operated) valve coupled to a faucet, and a filter bank coupled to the water supply line and to a second inlet port of the three-port solenoid valve. Activation of the three-port valve can stop the flow of unfiltered water through the faucet while allowing the flow of filtered water through the faucet.

摘要： A filtration system (1) has a filtration unit (2) with at least one filter element (4) for filtration of a fluid. The at least one filter element (4) has a main flow direction (C) for the fluid. The filtration unit (2) is configured to tilt the at least one filter element (4) around a tilting axis (B) to change an orientation of the main flow direction (C). A main unit (3) is fluidly connectable to the filtration unit (2) and includes a supply unit (18) configured to supply the fluid to the at least one filter element (4). A control unit is configured to control supplying and/or evacuating the fluid to/from the at least one filter element (4) and to control tilting of the at least one filter element (4) around the tilting axis (B).

摘要： A pre-filter skimmer system that reduces the amount of debris and particles entering the water filter in order to increase the longevity of the water filter is disclosed. The pre-filter skimmer system includes a chamber including an inlet and an outlet, wherein the water enters via the inlet and exits via the outlet. The water enters a first collector that is positioned at least partially within the chamber, the first collector configured to capture particles of a first size carried by the water. From here, the water enters a second collector that is positioned downstream of the first collector, wherein the second collector is configured to capture particles of a second size smaller than the first size that passed through the first collector.
