Abstract: A device for filtering air for a user comprising a frame formed in a generally oval-shaped band, the band encircling the user's head, with an upper portion above the user's head and a lower portion proximate to and spaced apart from the user's chin, an intake aperture formed in the frame, and an intake air filter covering the intake aperture. The device includes an air mover chamber attached with an air-tight seal to an inside surface of the frame and communicating on one end with the intake air filter and communicating on another end with a filtered air supply inlet inside the device and an air mover disposed within the air mover chamber and configured to draw air through the intake air filter and push air out the filtered air supply inlet. The device also includes an exhaust aperture formed in the frame and an exhaust air filter covering the exhaust aperture. The device further includes a transparent face shield attached with an air-tight seal to a front surface of the frame, the shield providing a space for air between an inside surface of the face shield and the user's face, and a fabric component comprising a first portion that is air permeable configured to cover the frame and filters and a second portion that is air impermeable extending from a back surface of the frame to cover a remaining portion of the user's head and encircle the user's neck.

Abstract: Methods and system for treating blackwater are disclosed. A pyrolysis chamber and a condensing heat exchanger are provided. A blackwater slurry, consisting of blackwater solids, water, and volatiles, is passed into the pyrolysis chamber. The blackwater slurry is heated to produce steam, to separate at least a portion of the volatiles, and pyrolyze the blackwater solids, the separated volatiles passing out of the pyrolysis chamber. The steam and separated volatiles are cooled in a condensing heat exchanger, condensing at least a portion of the steam and at least a portion of the separated volatiles as a contaminated water stream. A water-clarifying chemical is added into the contaminated water stream that reacts with the volatiles, resulting in a treated water stream.
