A waste compactor configured to compact waste into a plurality of compacted waste units for disposal in a waste container. There is a compaction chamber and a ram assembly disposed within the compaction chamber. There is an actuator interconnected to the ram assembly to apply a force to move the ram assembly from a retracted position toward an extended position to achieve a pressure on a compaction surface of the ram assembly as it compacts the waste. There is a plurality of apertures on at least one internal surface proximate of the compaction chamber through which liquid removed from the waste during the compaction mode exits the compaction chamber. There is also a liquid collection system, in communication with the plurality of apertures, to collect the liquid from the plurality of apertures. The liquid collection system includes an evaporation system configured to evaporate a portion of the liquid.

A gasifier includes a gasification chamber including an annular chamber wall with a top opening for introducing fuel into the gasification chamber. A restricted bottom outlet section of the gasification chamber has inwardly angled wedge walls encouraging a mass flow rather than a funnel-flow of fuel through the gasifier.

The present invention provides variable pore size filters. The variable pore size filters of the present invention comprise a fabric matrix, having a set pore size, wherein the fabric matrix is coated with a gel that expands and shrinks in response to a trigger. When the gel is expanded, the pore size of the filter is small and filtering is accomplished. When the gel is shrunken, the pore size of the filter is large and cleaning of the filter by a backwash or forward flush of fluid is accomplished.

Responsive gels and methods of use thereof

A filter system including a housing with an intake and an outlet, a pleated carbon filter disposed between the intake and the outlet for filtering out vapors entering the intake, and a hydrophobic solution dispersed about the pleated carbon filter to inhibit adsorption of water thereby increasing the adsorption capacity of the pleated carbon filter especially in high relative humidity environments. The hydrophobic solution is selected so that it does not decrease the adsorption capacity of the carbon filter. Also disclosed is a method of making such a filter.

Passive filtration system

A vapor extraction apparatus includes a gel sorbent capable of absorbing vapor directly into the liquid state and capable of disgorging the absorbed liquid in a phase-transition. The apparatus includes a housing adapted for movement from a first position, where it is exposed to a vapor-containing gas stream and a first environmental condition, and capable of moving to a second position, where it is exposed to a second environmental condition. A gel sorbent is disposed on at least one surface of the housing. The gel sorbs vapor from the gas stream as liquid when the sorbent is in its first position. The sorbent disgorges the liquid during phase-transition collapse when it is in the second position. A method of extracting vapor from a process gas stream includes contacting a phase transition gel sorbent with vapor under conditions sufficient for the gel sorbent to undergo a phase transition and absorb vapor as liquid inside the gel sorbent. The gel sorbent is then exposed to conditions sufficient for it to undergo a phase transition and disgorge the liquid from inside the gel sorbent. The disgorged liquid is removed from the gel sorbent.

A transverse flow, self-heating electrically conductive sorption system for separating species of different adsorption characteristics in a fluid includes a containment vessel, an electrically conductive permeable sorbent bed having a multiplicity of adsorption sites in said vessel; a porting structure for supplying contaminated fluid in a first direction at one surface of the bed and for receiving the contaminated fluid at another surface of the bed; and a pair of spaced electrodes for applying current through the bed in a second direction transverse to the first direction to self-heat the electrically conductive sorbent bed.

Transverse flow self-heating electrically conductive sorption system

An electrically conductive sorption and in situ regeneration system and method for separating species of different adsorption characteristics in a fluid includes flowing a contaminated fluid through an electrically conductive sorbent bed having a multiplicity of adsorption sites, and providing an electric current through the sorbent bed to heat the bed to increase the adsorption sites available for adsorption by the bed of the more strongly adsorbed specie by inhibiting adsorption by the bed of the less strongly adsorbed specie which might occupy adsorption sites in the bed.
