A waste bin for incorporation in a cabinet with a hinged door having a pivot pin extending vertically, laterally of the bin, the pivot pin being operatively mounted on brackets on the other side of the cabinet. A lid is hinged on a hinge pin operatively mounted on the side of the cabinet and opens automatically upon opening of the door, and is pivoted into its open position upon outward pivoting of the bin on the pivot pin when the door is opened, by means of a cam which engages the edge of the ...

A packing device is disclosed and comprises a hopper and a packer mechanism. The hopper is for receiving waste and has a substantially arcuate interior bottom surface and an aperture opening into the interior of the hopper. The aperture has a base towards which the interior bottom surface extends. The packer mechanism is mounted in the hopper for reciprocating movement along an arcuate path defined at least in part by the bottom'surface. In use, waste introduced into the hopper deposits on the i...

According to one aspect of the invention, there is provided a waste collection system for separating liquid waste from solid waste which includes a conveyor having an upper conveyor roller, a lower conveyor roller and an endless conveyor belt extending around the conveyor rollers. The upper run of the conveyor belt is upwardly concave. In cross section, the upper run has a lowermost portion and lateral portions diverging laterally and upwardly from the lowermost portion. The upper run is longitu...

A waste disposal system consists of a combustion chamber for vaporizing and burning sewage and for discharging the same with the products of combustion into a cyclone separator which retains dry solids and discharges the gaseous content.

A waste compactor for compacting waste in a container comprises a ram which reciprocates into and out of the container to compress the waste. The ram is preferably box-like and has a bottom opening which is normally closed by doors or flaps. Waste material can be fed into the compactor at a level above the opening and, when the doors are opened, preferably automatically during the ram stroke, the waste passes through the opening to the container, the doors being closed before the ram compresses ...

Treating waste with a system featuring a receiver tank having an inlet for receipt of waste into the system, means for connecting the receiver tank inlet to a source of the waste, at least one treatment tank connected downstream of the receiver tank for mechanical filtration of solid contaminants and adsorption of liquid contaminants contained in the waste. The treatment tank having a packed bed of adsorbent particles and means to aerate and fluidize the bed.

A waste compactor having a casing with an opening in the front wall thereof with a wheeled cart movable into the casing and holding a container to receive waste material with means for locking the cart to the casing, a loading chute carried by the cart and compacting structure in the casing including a fluid operated movable disc having a downwardly concave contour to have compacting forces acting radially inwardly toward the centerline of the compacting force and exerting a predetermined maximu...

A waste compactor having a casing with an opening in the front wall thereof with a wheeled cart movable into the casing and holding a container to receive waste material with means for locking the cart to the casing, a loading chute carried by the cart and compacting structure in the casing including a fluid operated movable disc having a downwardly concave contour to have compacting forces acting radially inwardly toward the centerline of the compacting force and exerting a predetermined maximu...

A waste compactor comprising a frame, a compactor member movable on the frame into and out of a cart associated with the frame. The cart is removable from the frame and comprises two sections pivoted to one another about a generally horizontal axis. When in one position, the sections define a bottom wall, side walls, and end walls having an open end for receiving a disposable waste container. The cart is removable from the frame so that one of the sections may be pivoted about the horizontal axi...

A sparger comprising a porous propellor atop a hollow rotatable shaft connected to a gas source and means for rotating the shaft whereby gas forced into the hollow shaft leaves the sparger through the pores of porous blades of the propellor. The sparger is capable of quickly and efficiently dispersing a gas in a liquid and is typically mounted inside a liquid-containing chamber (such as a waste water chamber) in such a manner that the rotatable, hollow shaft enters the chamber through a water ti...
