A portable liquid filtration device includes a GPS tracking unit, a portable housing, an inlet configured to receive non-potable water, and an ozone chamber positioned within the portable housing. The ozone chamber is configured to generate an ozone gas from received air. The device also includes a filtration duct positioned within the portable housing and downstream from the inlet. The filtration duct includes at least one oxidation chamber configured to mix the received water with the ozone gas, and at least one ultraviolet (UV) chamber downstream from the at least one oxidation chamber and including a UV lamp positioned adjacent the water within the filtration duct. The device further includes an outlet positioned on the portable housing and downstream from the filtration duct. The filtration duct is operable to output at least 150 liters per hour of the received water from the outlet as potable water.

A system and a method comprises a chamber configured to receive a flow of a wastewater mixture from an input. A first baffle wall forms a first channel within the chamber. The wastewater mixture flows from an input to an output of the first channel. A second baffle wall forms a second channel and a third channel within the chamber. The wastewater mixture flows from the output of the first channel to an input of the second channel to an output of the second channel to an input of the third channel to an output of the third channel. The output of the third channel is configured to direct the flow to an output from the first chamber.

A fluid treatment system for treating a fluid, the system including structure for moving a fluid therethrough the system, the structure for moving the fluid including a first inlet and a first outlet, further a primary fluid filter having a primary fluid filter inlet and a primary fluid filter outlet, wherein the primary fluid filter inlet is in fluid communication with the first outlet. Included with the system is a primary ultraviolet light module having a primary ultraviolet light module inlet and a primary ultraviolet light module outlet, wherein the primary ultraviolet light module inlet is in fluid communication with the primary fluid filter outlet and a secondary fluid filter having a secondary fluid filter inlet and a secondary fluid filter outlet, wherein the secondary fluid filter inlet is in fluid communication with the primary ultraviolet light module outlet, wherein the secondary fluid filter outlet discharges a first treated fluid.

The apparatus for filtering and dispensing drinking water is disclosed which includes a container having an interior space with a dividing wall defining a first chamber for receiving unfiltered water and a second chamber for storing filtered drinking water, wherein a passage is formed through the interior wall adjacent a bottom surface of the container to provide fluid communication between the first and second chambers, and wherein at least one multi-layered filter pack is disposed across the passage to filter water flowing from the first chamber to the second chamber under force of gravity.

A sewage treatment system uses a multi-stage process to treat waste materials. Sewage is contained in a first tank, from which liquid waste is filtered and transferred to a second tank, where the first tank retains solid waste. The second tank may contain a plurality of chambers, with the chambers connected using ports for fluid communication. Liquid waste in the second tank undergoes aerobic digestion, where an aeration device may aid in the digestion process. The second tank may also include a UV light source to reduce bacteria. The treated liquid from the second tank may be clean enough to be discharged directly into a leach field which would not meet standards for conventional leach fields.

A portable water bottle has a bottle body, a lid assembly detachably connected to an upper end of the bottle body, a filter mounted in the lid assembly, a base detachably connected to a lower end of the bottle body, a temperature control module mounted in the base, and a power module mounted in the base. Liquid stored in the bottle body can be filtered by the filter when being poured out of the bottle body, so as to allow a user can drink the liquid directly and immediately. Moreover, the temperature control module is capable of heating or cooling down the liquid in the bottle body, so as to provide the user with the liquid having the temperature that is suitable for ambient it temperature or physical conditions of the user.

The invention relates to a portable, solar-thermal device for the treatment of drinking water from waste water, comprising an evaporation container that accommodates the waste water, a condensation apparatus having a flow connection to the evaporation container, and a separator arranged between the evaporation container and the condensation apparatus for separating and leading away the condensate obtained in the condensation apparatus. According to the invention, the separator has passage openings for the transfer of water vapor into the condensation apparatus, which is arranged on the top side of the device in the operating position of the device, and a drain opening for the condensate arising in the condensation apparatus, which drain opening can be connected to a collecting container, wherein the evaporation container, which is arranged on the bottom side of the separator, is designed as a flexible film bag.

Described herein are devices for providing drinking fluid from feed sources comprising: a first reservoir, a filter for mechanically removing particles and a second reservoir for receipt of the processed feed fluid. A continually disinfecting element is disposed in either or both reservoirs to remove additional materials from the fluid. Drinking fluid is provided in a portable device. Optional light sources are provided to interact with the disinfecting elements and/or provide an indication of the contained suitability of such disinfecting elements. A method for creating drinking fluid from a feed source is also disclosed.

A portable, collapsible still includes an upper reservoir for coolant water, an intermediate condensing chamber, and a lower reservoir of an aqueous solution, for example, seawater. A condenser coil is in fluid communication with the headspace in the lower reservoir above its fluid level, with the coil extending into the condenser chamber and to an external fluid port. A reflector is positioned below the lower reservoir, to reflect sunlight onto the lower reservoir to heat it. As the water vapor pressure in the lower reservoir increases as a result of the solar heating, the water vapor enters the coil, which is bathed in the lower temperature coolant water from the upper reservoir, causing the water vapor to condense inside the coil and thus be available for drinking.
