A portable, personal advanced-oxidation water treatment system based on ozone and a catalyst such as titanium dioxide that can cycle and purify water to make it potable by removing organic contaminants. The unit can be used for long periods of time without having to replenish the active portions. The unit can be carried in a backpack or in a vehicle. Fresh water is typically loaded into the unit, and the unit is cycled until the water is pure enough to drink. A battery is used to produce ozone and to cycle the water through a reaction vessel and can optionally be charged with a small solar panel The unit can also be powered directly from a vehicle.

A mobile power generation/water purification system includes, in a housing thereof: a photovoltaic power generation device; a battery that stores electricity generated by the photovoltaic power generation device; a control unit that receives electric power from the battery; and a drive means controlled by the control unit and using the battery as an electric power source. A water purification device is disposed inside the housing in a single flow path connectable to a suction hose and an outflow hose. The drive means of the water purification device is a plurality of drive pumps which are electrically connected to the battery by respective conductive cables. The photovoltaic power generation device is a solar panel wound around a rotation shaft inside the housing. The solar panel can be pulled out directly in a horizontal direction from a horizontally elongated cutout window of the housing.

A photovoltaic evaporation and distillation system for the recycling of wastewater to potable water is disclosed herein. The system is comprised of six components that work in conjunction to produce both a source of reusable water for indoor appliances that produce greywater (or irrigation use), and potable water.

The present invention relates to water purification using solar energy. More specifically, systems and methods according to the present invention collect solar energy to heat non-potable water in a super-insulated structure. Compressed heated air is injected to evaporate water vapor out of brackish water, saltwater, or dirty water, thereby creating saturated air. The saturated air is drawn through a cooling tower and distilled water is precipitated. The systems and methods employ heat recovery and recycling processes to maximize energy efficiency.

A wirelessly controlled device for atmospheric water generation is provided. The device comprises an atmospheric water generator for generating filtered potable water and a wireless external control system. The wireless external control system comprises one or more display presentation pages for displaying a plurality of operating parameters for the atmospheric water generator, including content display with a variety of operation parameters and historical water collection data for operation of the atmospheric water generator. The wireless external control also has one or more display pages configured for user input for a user to select one or more water generation parameters for operation of the atmospheric water generator. Once the device is directed by the wireless external control system to generate water, the device is capable of automatic water generation until the device fulfills the one or more set water generation parameters.

This disclosure provides systems and methods for generating potable water from contaminated water sources, particularly well water. By eliminating the purified water holding tank, employing a combination of source tank with carbon and reverse osmosis filters in series, and using an actuated pump to supply impure water from the source, a simple on-demand system is provided that is especially adapted for use in remote locations. The system and method are particularly useful where only direct current power, such as from a solar photovoltaic panel power, is available.

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.

A potable water producing system for disposition at a salt water body and methods of producing potable water are provided. The system includes a wave energy conversion system (AWECS) and a portable filtration system. The AWECS forms a floating articulated barge having an onboard desalination system including reverse osmosis membranes. The filtration system is a sand filter residing on a damping plate submerged in the salt water body and filters the adjacent salt water for providing filtered salt water to the onboard desalination system. Wave action on the articulated barge provides energy to pump and pressurize the filtered salt water from the sand filter to the reverse osmosis membranes to produce potable water. The wave action on the articulated barge effects shaking of the reverse osmosis membranes, thereby rendering them self-cleaning. The potable water can be used for various applications, e.g., bottling, replenishing aquifers, ground and/or aquifer remediation, irrigation, etc.
