A portable drinking water filter system, such as a pitcher, having a sleeve and a floatable body including a filter opening configured to receive a water filter, the floatable body having a seal extending outward from an outer surface of the floatable body. The floatable body is disposed in a sleeve cavity such that a body seal engages the sidewall and restricts water from passing between the floatable body and the sidewall. The seal is configured to create friction with the sidewall, wherein the friction created when the floatable body rises in the sleeve is different than when the floatable body lowers in the sleeve. The friction created when the floatable body rises in the sleeve is greater than when the floatable body lowers in the sleeve, allowing the floatable body to auto-retract toward a cavity base without burping.

A filtering device includes a filter tank, a first drum filter both ends of which are supported, and a cantilever second drum filter. A first end portion of the first drum filter is supported on a first sidewall of the filter tank. A second end portion of the first drum filter is supported on a second sidewall. An end portion of the second drum filter on the supported side is supported on the first sidewall. Between an end portion of the second drum filter on the non-supported side and the second sidewall, a communicating part is formed. A first jetting section jets a fluid against an outer circumferential surface of the first drum filter. A second jetting section is arranged in the vicinity of the second drum filter and jets the fluid against the second drum filter.

An effluent collector includes a filtrate receiving portion having a filtrate opening, and a pressate receiving portion having a pressate opening. The effluent collector includes a diverter barrier adjustably positioned above the pressate receiving portion. The diverter barrier is configured to adjustably direct at least a portion of a flow path toward or away from the pressate receiving portion.

A modular support structure comprising multiple chord or arc modules configured to selectively fixedly engage adjacent modules to define a completed annular support structure configured to support a rotary element of a rotary filter. The modular chord or arc segments may fixedly engaged an adjacent chord or arc segment through a fixing mechanism selected from the group consisting of: fasteners, clamps, pins, bolts, locks, locking mechanisms, key and socket mechanisms, spot welding, welding, adhesives, and other fastening mechanisms configured to engage and disengage adjacent chord or arc modules with ease.

A solid-liquid separator for separating a solid phase from a liquid phase in a solid-liquid mixture is provided. The solid-liquid separator includes a basket and filter assembly housed coaxially within a tank such that when the basket and filter assembly rotates the liquid phase moves through the filter of the basket and filter assembly into the tank and is discharged from the solid-liquid separator. The solid phase is retained on the filter of the basket and filter assembly and travels vertically up the filter of the basket and filter assembly where it is discharged from the solid-liquid separator.
