A method and an apparatus for treating a liquid containing impurities may include a filtering chamber configured to permit granular media to interact with liquid containing impurities, thereby removing impurities from the liquid to produce filtrate; a filtrate section for receiving the filtrate; a gas supplying system for delivering gas to the granular media in the filtering chamber for transport of a portion of the granular media to a granular media washer; a reject section in fluid communication with the granular media washer for receiving a reject mixture comprising liquid and impurities from the granular media washer; and a control unit that is configured to determine whether the portion of the granular media is being transported properly based on an amount of reject mixture in the reject section.

A self-supporting filter media as well filter element and filtration system including the same is provided. A method of manufacturing the self-supporting filter media is also provided. The self-supporting filter media is formed such that it has a rigidity which permits the omission of filter support cage or other internal media support structure.

The disclosed invention pertains to a novel device and method for effectively emptying water treatment vessels. This innovation may provide a sturdy, aluminum-framed apparatus featuring a cradle and adjustable legs. The water treatment vessel may be securely fastened onto the cradle after the frame is first adjusted to a suitable height using the device's adjustable legs. A water hose may be attached to the device's fitting, directing water into the vessel for rinsing filter media or resin. The inverted vessel's contents may flow onto a washout tray for collection. This innovative device may enhance stability, ease of use, and safety, making it ideal for emptying water treatment tanks or vessels of varying shapes and sizes.

A water filtration system is provided. Generally, the filtration system is usable with well water to remove contaminants such as metals, among many other components. The filtration system utilizes a granular filter medium, such as, for example, washed sand. The water filtration also includes a multi way backwash system that allows cleansing of the filter medium by passing backwash water in a first clockwise direction as well as an opposite counter clockwise direction. This rocks the filter medium back and forth by the backwash fluid flow, providing improved cleansing of the filter medium as well as better overall filter operation.

A pipeline filter assembly comprising a base assembly, an outer wall, and a lid assembly. The base plate has a pocket to hold a tool for opening and closing a drain plug. The outer wall has a lower end portion and an upper end portion, wherein the upper end portion comprises a lower collar, and the lower collar comprises threading around an exterior surface thereof. The lid assembly is configured to couple to the lower collar of the outer wall. The lid assembly has an upper collar configured to mate with the lower collar. The upper collar has at least one housing that is coupled to the upper collar, and at least one biasing clip pivotally mounted within the housing for releasable engagement with the lower collar.

The present technology relates to control systems for use with fluid treatment systems. In one embodiment, for example, a fluid treatment system includes a vessel configured to receive a fluid having one or more constituents and to separate one or more constituents from the fluid. The system can also include a tube extending along at least a portion of the vessel and a sensor. The tube can be in fluid communication with a pressurized air source, and the sensor can be configured to obtain a measurement of an operating parameter. The system can also include a controller in communication with the sensor and pressurized air source. The controller can execute one or more algorithms to determine a filter parameter based on the measurement of the operating parameter, compare the filter parameter to a threshold, and, based on the comparison, activate or deactivate the pressurized air source.

A water purification kit/system comprises a first pot, a second pot, a filter, and a condensation collector. The first pot and the second pot are configurable into first and second configurations, wherein, in the first and second configurations, the first pot is either an upper pot or a lower pot, and the second pot is the other of the upper pot and the lower pot. In the first configuration, the upper pot and the lower pot form a water filtration system. In the second configuration, the upper pot and the lower pot form a water distillation system.

A tiltable filter canister including a housing and a lid adjacent to each other. The lid encloses the housing to form an interior of the tiltable filter canister. A seal may be disposed between the housing and the lid for forming a vacuum tight seal. A handle is connected to the lid, the handle having a first position and a second position. When the handle is in the first position, the seal may form the vacuum tight seal. A pin connects the handle to the lid and allows the handle to rotate between the first position and the second position. An arcuate surface may be present on the handle with a first protrusion for receiving a stop and a second protrusion. A first canister position of the tiltable filter canister is configured for performing a filtering operation and a second canister position of the tiltable filter canister is configured for performing a maintenance operation. A filtration media may be disposed within the interior of the tiltable filter canister for filtering a fluid during the filtering operation.

A device is provided that provides an unbiased filtration effect and an effect of removing captured substances through backwashing by causing a fluid to uniformly pass through a filter element over the entire length in an axial direction at the time of backwashing so as to efficiently rotate a captured-substance removal tool in a filtration unit 1 which includes the captured-substance removal tool 20 axially supported inside the tubular filter element 2 to be rotatable.
