A separator device for separating fibrous material from wastewater has a housing comprising at least one inlet for wastewater, at least one first outlet for filtrate, at least one second outlet for the fibrous material, and least one hollow strainer element disposed in the housing, the inlet opening into the interior of the strainer element and the first outlet being disposed in an intermediate space between the housing and the strainer element. At least one strainer element of the separator device is movably disposed in the housing and coupled to a drive for displacing the strainer element. The invention further relates to a method for separating fibrous material from wastewater.

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 vacuum and/or pressure filtration device includes a filter drum defining a drum axis and it is supported rotatably around the drum axis. The filter drum includes an outer jacket, by which a plurality of filter cells are formed, which extend along the drum axis, which are arranged adjacent to each other all around the drum axis, and which are equipped on their outer side with a filter medium; and an inner jacket, which is arranged adjacent to the outer jacket, which has an inner jacket outer surface, which limits the filter cells radially inside such that by the inner jacket outer surface a plurality of draining surfaces are formed, on which the liquid passing through the respective filter medium during filtration of the suspension can drain as a filtrate. The filtration device filters a suspension having solid and liquid components.

A method of filtering a wastewater stream and a filter media comprising a non-woven felt material for filtering particles from a wastewater stream wherein the non-woven felt material filter is positioned within a wastewater stream from a washing machine and wherein the filter is positioned downstream of a washing machine wastewater drainage outlet. The filter media may be configured for use with a gravity based wastewater filter mountable to a surface external to the washing machine or may be configured for use with a motorized wastewater filter mountable to a surface external to the washing machine.

A filter drum including: a drive shaft via which the filter drum is rotatably supportable and rotatably drivable; a filter drum body which is formed in a manner separated from the drive shaft, to which the drive shaft extends centrally and which filter drum body includes a first drum end wall, a second drum end wall, and a drum jacket wall which extends along the drive shaft between the first drum end wall and the second drum end wall and connects the first drum end wall and the second drum end wall to each other; and a first clamping ring set and a second clamping ring set, corresponding to the first drum end wall and the second drum end wall, respectively, by which, in a respective manner, the first drum end wall and the second drum end wall are, via radial clamping, fixedly connected to the drive shaft such that a driving torque applied to the drive shaft is correspondingly transmittable from the drive shaft to the first drum end wall and/or the second drum end wall and, thereby, to the filter drum body via the first clamping ring set and/or the second clamping ring set, respectively. The filter drum can be used in a vacuum and/or pressure filtration device for the filtration of a suspension having solid and liquid components.
