Preferably, the support membrane is formed of a titanium metal.

Described are methods and devices for the treatment of fecal matter. A column reactor is used to smolder fecal matter to produce and a volatile components stream and smoldered media. The volatile components stream may be subject to catalysis to reduce the emission of noxious substances and/or generate heat energy. Also described is the use of a turntable for removing smoldered media from the column reactor.

A method for treating wastewater involves electrolyzing a stream of seawater and wastewater mix within one or more electrolytic cells mounted outside a batch tank. The electrolyzed stream is piped to a quelling chamber which is mounted above the batch tank. A diluted polymer solution is injected at upstream of an in-line mixer piping into the quelling chamber substantially concurrently with the electrolyzed stream. The polymer solution and the electrolyzed stream are dispersed as a fine shower over residual seawater and wastewater in the batch tank. The polymer solution facilitates flocculation of the suspended solid particles and creates a distinct buoyant layer of flocculated solid particles attached with micro bubbles. A substantially clarified effluent is separated from the flocculated layer and neutralized prior to discharge. The flocculated layer is pumped from the batch tank to a dewatering system where entrained solids are compacted to a desired level. A centrate generated during the solids/sludge dewatering step is recirculated to the batch tank prior to addition of seawater during a subsequent treatment cycle as a supplement to the seawater.

A bioreactor for a water treatment system includes an aerator tank configured to receive an influent liquid, and a clarifier positioned in the aerator tank, the clarifier having a generally conical shape and defining a downwardly-facing opening. An interior of the clarifier is in communication with the aerator tank, external to the clarifier, at least via the downwardly-facing opening, and wherein the clarifier is positioned non-concentrically with the aerator tank. The bioreactor further includes a plurality of aeration vents positioned proximal to a bottom of the tank and configured to direct air into the aerator tank, and an effluent outlet positioned in the clarifier. A relatively clean effluent liquid, in comparison to the influent liquid in the aerator tank, exits from the clarifier via the effluent outlet.

The disclosure relates to a portable waste collection and sanitation system designed to handle liquid and solid waste, and while conserving water and minimizing odors. The sanitation system is also designed with modular components adapted for in-home installation, where the system can be quickly disassembled and relocated as needed, such as for moving the components to a new location based on environmental conditions.

A disinfection apparatus for treating waste may include a housing having an inlet and an outlet; a conveying mechanism which is disposed within the housing and which extends at least substantially along the housing from the inlet to the outlet; and a heating mechanism configured to transfer heat to the housing so as to heat an internal space of the housing to create a heated environment within the housing. A method of treating waste may include providing the waste in a heated environment within a housing of a disinfection apparatus; and conveying the waste, via a conveying mechanism of the disinfection apparatus, along a length of the housing of the disinfection apparatus. According to various embodiments, the method may further include heating, via a heating mechanism of the disinfection apparatus, the housing so as to heat an internal space of the housing to create the heated environment within the housing.

A compact waste combustion system deployed within a portable toilet has a burn chamber that includes a processor, a burner, a trapdoor mechanism configured to seal an entrance to the burn chamber when the compact waste combustion system is operated in a first mode and a waste receptacle configured to feed waste material to the burn chamber through the trapdoor mechanism in a second mode of operation. The processor may be configured to detect presence of a waste in the waste receptacle, configure the system to operate in the second mode and to pass waste into the burn chamber, configure the compact waste combustion system to operate in the first mode after the waste has passed into the burn chamber, and activate the burner when the compact waste combustion system is operated in the first mode and the waste is located in the burn chamber.

A bioreactor for a water treatment system includes a tank configured to receive an influent liquid, a separator structure positioned in the tank, the separator structure having a frustoconical shape and defining a downwardly-facing opening proximal to or at a bottom of the separator structure, an interior of the separator structure being in communication with the tank, external to the separator structure, at least via the opening, an aeration vent positioned proximal to a bottom of the tank and configured to direct air into the tank, but not directly into the interior of the separator structure, and an effluent outlet communicating with the interior of in the separator structure, proximal to a top of the separator structure, a relatively clean effluent liquid, in comparison to the influent liquid in the tank, exiting from the separator structure via the effluent outlet.
