Described is a macerator and process for using the macerator to reduce the particle size of a particulate containing slurry that is introduced to the macerator. The macerator comprises a housing that defines a chamber an inlet and an outlet, the inlet configured to receive a flow of slurry, two or more elongate concentric bodies located within the chamber to define a gap between the surface of the outer body and the inner surface of the housing, the bodies having a first end and a second end, at least one of the bodies rotatable about an axis, and each body comprising a plurality of apertures to define a flow path through each body, from the housing inlet to the housing outlet, a baffle or baffles that extend substantially the width of the gap from the first end to the second end of the bodies to define a first portion that contains the inlet, and a second portion that contains the outlet, and wherein the baffle or baffles substantially inhibit passage of slurry between the two portions via the gap such that the slurry is directed through the body apertures, a motor to drive the rotating body or bodies, one or more injectors that inject liquid into the gap, wherein at least one of the injectors is located in the first portion. The particle size of the outlet slurry is less than the particle size of the inlet slurry.

A food waste disposer includes a transfer pipe connectable to a dishwasher to transfer washing water containing food waste from the dishwasher, a pump to be installed to the transfer pipe to provide power to transfer the washing water through the transfer pipe, a separation device connectable to the transfer pipe to separate the food waste from the washing water transferred from the transfer pipe, and a storage container detachably coupled to the separation device to receive the separated food waste from the separation device and to dispose the received separated food waste.

Solid waste, for example source separated organics (SSO) or commercial and industrial (C&I) waste or both, are treated by first pressurizing the waste against a screen to produce a solids fraction and a liquid fraction. The liquid fraction can be treated in an anaerobic digester. The solids fraction is pulverized or milled, for example with a hammer mill, preferably after being diluted. The pulverized or milled waste is separated again to provide a second solids faction and a second liquid fraction. The liquid fraction can be treated in an anaerobic digester. The solids fraction is primarily inert and can be landfilled, preferably after being washed.

The invention relates to the field of kitchen appliances and discloses a food waste disposer, the food waste disposer has a switching component arranged to a discharge outlet of the food waste disposer, the switching component has a first pipe; a second pipe; a first baffle that flips in an anti-gravity direction along a discharge direction to connect or isolate a discharge outlet and a sewer pipe; a first sealing ring; and a limit block to prevent the first baffle from flipping. The invention also discloses an integrated sink and integrated cabinet both have the food waste disposer with a switching component arranged to a discharge outlet of the food waste disposer.

A comminuting device for solids-conducting liquids includes a housing with an inlet opening, an outlet opening, and a housing interior extending from the inlet opening to the outlet opening, a first comminuting shaft extending through the housing interior and arranged to rotate about a first comminuting axis. A second comminuting shaft extends through the housing interior and is arranged to rotate about a second comminuting axis. A screening device has a screening wall comprising a plurality of slots arranged in the housing interior adjacent to the first comminuting shaft. A clearing device has a plurality of clearing elements which can be moved relative to the screening wall along a movement path and which extend through the plurality of slots starting from a clearing shaft arranged on one side of the filter wall to at least one portion of the movement path.

A comminuting device for solids-conducting liquids includes a housing with an inlet opening, an outlet opening and a housing interior space which extends from the inlet opening to the outlet opening. A first comminuting shaft arranged for rotation about a first comminuting shaft axis, and a second comminuting shaft arranged for rotation about a second comminuting shaft axis through the housing interior space. A first screen device is arranged in the housing interior space adjacently with respect to the first comminuting shaft with a first screen wall having a multiplicity of slots. A first evacuating device with a plurality of evacuating elements which can be moved along a movement path relative to the screen wall extends through the plurality of slots on at least one portion of the movement path.

A grinder accessory is useful for a pump in a wastewater application. The grinder accessory has a cutter plate and a cutting body that co-act on solids, especially fibriform solids. The cutter plate has first and second planar faces, mounted in an inlet of the pump, with a plurality of through holes and a central aperture. The cutting body is poised atop the first planar face and extends through the central aperture to rotationally couple with a drive shaft of the pump. A central hub of the cutting body has a plurality of arms that extend radially proximate to the first planar face, so that a leading edge of the arms interacts with the through holes on solids passing therethrough. A housing defines a cutting chamber around the cutter plate and the cutting body to protect them and to induce swirling action.
