Abstract: A system for processing leachate is provided. The system has an ultrafiltration unit that receives the leachate and produces both an ultrafiltration permeate and an ultrafiltration reject. The system recovers the ultrafiltration reject and recirculates it through the ultrafiltration unit to produce a combined ultrafiltration permeate. The system also has a nanofiltration unit that receives the combined ultrafiltration permeate and produces both a nanofiltration permeate and a nanofiltration reject. The system also has a carbon filtration system that receives the nanofiltration reject and produces a carbon filtration permeate. The system also has a system output that receives the nanofiltration permeate and the carbon filtration permeate and produces a mixture of both permeates as an output mixture.

Abstract: The present invention is directed to a suppression system in which a carrier gas and suppression liquid are contained in a common containment vessel and separated by a separation member. The separation is one or more of movable, deformable, or shape changing in response to pressure exerted by the stored gas.

Abstract: The present invention is directed to a sorbent comprising a disordered polyvalent metal oxide on the surface of an inert substrate. The substrate can be a layered silicate, such as vermiculite, an aluminosilicate such as montmorillonite, or a nonlayered silicate such as a zeolite. The sorbent removes ionic contaminants, such as arsenic, from process streams.

Abstract: The present invention is directed to a system for removing amalgam particles and/or dissolved metals, such as mercury and silver from dental effluents. The system can include one or more of a particle collection device and a dual-purpose line cleanser.

Abstract: A decontaminating system 200 is provided that includes: (a) a decontaminating apparatus 100 including (i) an electrically conductive scrubbing shoe 104 having an inlet 204 for a gel-like material and (ii) an insulating standoff 116 positioned between the scrubbing shoe 104 and a surface 120 to be decontaminated to maintain a desired distance between the scrubbing shoe 104 and the surface 120; (b) a reservoir 216 for the gel-like material 124, the reservoir 216 being in communication with the inlet 204; and (c) a voltage source 224 in communication with the electrically conductive scrubbing shoe 104, whereby a current is passed through the gel-like material 124 applied to the surface 120, thereby removing contaminants from the surface 120.
