摘要： An air filtering mask is disclosed which includes a rigid component and a flexible component. The rigid component and the flexible component combine to form a space over a user's mouth and nostrils, to form a seal therearound and to maintain the mask in place. The mask also includes an exhaust port with an exhaust filter and an intake port with an intake filter. The mask further includes an air mover pulling exhaust air out the exhaust port, thereby drawing intake air through the intake port.

摘要： A system for sanitizing water in a container is disclosed. The system includes a sanitizing chamber, separate from the container, sized to hold a small portion of the water from the container. A first conduit conveys water from the container to the chamber. A second conduit conveys water from the chamber to the container. A pump moves water from the container, through the first conduit into the chamber and from the chamber, through the second conduit into the container. A heater heats the water in the sanitizing chamber to a temperature and for a time sufficient to destroy or deactivate undesirable microorganisms. The first and second conduits each comprise at least one heat exchanger whereby water in the first conduit is heated by the water in the second conduit and water in the second conduit is cooled by water in the first conduit.

摘要： 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.

摘要： 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.

摘要： There is described a shower system that includes a showerhead fixture and a base connected by conduits. The showerhead fixture includes an inlet for receiving pressurized water. A diverter is configured to divert at least a portion of the pressurized water to the base. The showerhead fixture also includes a second inlet fluidly connected to a recirculating showerhead portion with a plurality of showerhead jets for expelling mixed water received from the base. The base is configured to create a reservoir of water on a shower floor and includes a venturi pump capable of using pressurized water from the showerhead fixture to draw in water from the reservoir into the stream of pressurized water. The mixed water is sent from the base to the jets in the showerhead fixture to thereby increase the volume of water expelled from the showerhead.

摘要： A system for sanitizing water in a hot tub is described. The system includes a sanitizing chamber, separate from the hot tub, and sized to hold a small portion of the water from the hot tub. A first conduit for conveys water from the hot tub to the sanitizing chamber. A second conduit conveys water from the sanitizing chamber to the hot tub. A pump is provided that moves water from the hot tub, through the first conduit into the sanitizing chamber and from the sanitizing chamber, through the second conduit, back into the hot tub. A heater heats the water in the sanitizing chamber to a temperature and for a time sufficient to destroy or deactivate undesirable microorganisms.
