An apparatus for separating heavy solids from an effluent, for example wool scouring effluent, comprising a tank having a solids discharge outlet at its base and an ultra-sonic sensor located at a predetermined distance from this outlet. Means responsive to the output of the sensor, for example a solonoid controled valve, are provided for opening the discharge outlet when the solids concentration exceeds the preset limit. Preferably, a secondary settlement tank immediately below and directly com...

A lid for an industrial waste container comprises a first lid section which is of relatively rigid, heavy construction and which is hinged to one side of the container. The first lid section defines an access opening to the container, which access opening is closed by a second lid section of relatively light weight. The second lid portion is hinged to the first lid section and a releasable catch is provided to releasably secure the first lid section in a closed position. Biasing means are provid...

Burning a waste fuel blend at very high temperatures (typically greater than 4000 deg. F.) for a very short period of time (typically a matter of milliseconds) in a primary combustion zone to break the complex hazardous/toxic hydrocarbons into less complex chemicals (such as CO, CO.sub.2, H.sub.2, OH, HCl, and Cl.sub.2), passing the products of the primary zone into a secondary zone in which the products are maintained for a longer time (typically about 2 secs.) in turbulent conditions with exce...

A waste receptacle comprising a two-part outer housing and a disposable two-part inner waste container each having a bottom part and an apertured top part interconnectible around their perimeters, the said perimeters of the inner container parts being arranged to be received between the perimeters of the outer housing parts and sealingly interconnected by the action of interconnecting the outer housing parts.

An apparatus for collecting both bagged and loose waste. The apparatus includes a hopper which is in flow communication with a waste receptacle for collecting bagged or bundled waste. The apparatus also includes a suction mechanism which draws loose waste into the waste receptacle. The hopper and the suction mechanism are arranged on the apparatus so that the hopper and/or suction mechanism can be used to collect waste without having to modify the suction mechanism and/or hopper.

A method of treating inorganic solid waste in a bath of molten metal contained in a vessel (3) which has a space above the bath and a waste gas outlet (11) is disclosed. The method comprises injecting waste into the bath to form a primary reaction zone (13) in which there are reactions between the waste and the bath or in which the waste undergoes a change of phase to convert the waste into more readily recoverable or disposable products. The method further comprises injecting oxygen-containing ...

A waste debarker 10 comprises a housing 12 in which is mounted a rotatable first cutting drum 14 and a rotatable second cutting drum 16 arranged in a longitudinally spaced relationship with respect to the first drum 14. The first drum 14 has a plurality of circumferentially extending flanges 24 spaced along the length thereof for supporting cutting teeth 26 thereon. The second drum 16 has a plurality of discrete lugs 34 arranged on its surface for supporting cutting teeth 26 thereon. The lugs 34...

A waste container includes a hollow body having an open top end, a cover detachably provided on the open top end, and a press member movably mounted on the cover and having a plate portion disposed horizontally inside the hollow body. The press member is vertically movable inside the hollow body to compress garbage inside the hollow body.

The method of disposal of hydrocarbon sludge (such as petroleum-derived sludge residue from a hydrocracker) comprises mixing the sludge with spent silica-alumina catalyst particulate fines, of particle size not exceeding 50 micrometers, so as to form friable aggregates of the particulate fines in which the individual particles are bound together by the sludge. The resulting formulation is useful, inter alia, for road-making.

A waste container includes a generally cylindrical double-wall drum having separate spaced-apart inner and outer sidewalls and separate spaced-apart inner and outer bottom walls. The inner and outer sidewalls are continuously connected along their upper ends and the inner and outer bottom walls are connected at a plurality of spaced-apart locations. A double-wall lid is provided to seal the container. A neck portion is formed at the upper end of the drum and includes a series of buttress threads...
