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 septic system, including a septic tank and a pipe positioned within the septic tank, is provided. The pipe receives sewage and provides a flooded, anaerobic environment for sewage passing therethrough. The outlet of the pipe is positioned inside the septic tank and is optionally spaced from the outlet of the septic tank. In operation, the sewage introduced into the pipe generally separates into a solid portion comprising sludge, which remains in the pipe, and a liquid portion, which passes through and around the sludge. In one embodiment, the septic system has an absence of a sump chamber upstream of the septic tank.

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.

A round meander septic tank includes an elongate baffle that divides the interior space of the tank into two semicircular chambers. Untreated wastewater is introduced to the first chamber through an inlet located near the first end of the baffle. The wastewater flows through the first chamber to a portal at the second end of the baffle and passes through the portal into the second chamber. A wastewater outlet from the tank is located in the second chamber near the first end of the baffle. Wastewater passing through the portal flows through the second chamber to the outlet and out of the tank. The baffle and the shape of the septic tank increase the distance that the wastewater must flow from the inlet to the outlet as compared to a rectangular meander tank with a single baffle.

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.

Disclosed are a method and apparatus of automatic flow control based on sensed effectiveness indicators to produce effectively treated water with a portable water treatment unit. In one embodiment, a method for treating water includes activating a pump a first speed to initiate water at a first flow rate through a chemical treatment unit that is initiated to deliver a treatment chemical. An effectiveness value of the chemical treatment is measured from a sensor and compared to a reference value in a physical memory and/or a feedback circuit. It is determined that the effectiveness value is less than a threshold value. The first speed of the pump is adjusted automatically to a second speed to change to a second flow rate. The second flow rate adjusts the concentration of the treatment chemical to ensure an effective treatment, efficient usage of the chemical treatment, and/or efficient use of a power source.

A portable drinking water filter system, such as a pitcher, having a sleeve and a floatable body including a filter opening configured to receive a water filter, the floatable body having a seal extending outward from an outer surface of the floatable body. The floatable body is disposed in a sleeve cavity such that a body seal engages the sidewall and restricts water from passing between the floatable body and the sidewall. The seal is configured to create friction with the sidewall, wherein the friction created when the floatable body rises in the sleeve is different than when the floatable body lowers in the sleeve. The friction created when the floatable body rises in the sleeve is greater than when the floatable body lowers in the sleeve, allowing the floatable body to auto-retract toward a cavity base without burping.

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 advanced oxidation (AO) chamber configured to mix the received water with the ozone gas, and at least one ultraviolet (UV) chamber downstream from the at least one AO 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 400 liters per hour of the received water from the outlet as potable water.

Tertiary wastewater treatment wherein a tank is divided into a primary separation chamber, an aerobic chamber, and a clarifier chamber. Media are preferably disposed in the aerobic chamber and most preferably, the media can be contained in one or more porous containers. A recirculation path is preferably provided between the aerobic chamber and the primary separation chamber. In one embodiment, the recirculation between the two chambers can be powered by an air lift pump.

A portable fluid-sanitizing system and assembly configured for personal use are provided. The system and assembly combine mechanical and electrical methods for removing and/or deactivating harmful chemicals, molecules, atoms, ions, and even microorganisms from fluid. The system and assembly comprise a hand-holdable container that is sized to receive a filter, such as an activated carbon block capable of adsorbing or otherwise capturing a variety of undesirable contents from the fluid. Ultraviolet lights may be disposed along an inner or outer portion of the container and placed so that their emissions penetrate any fluid contents of the container. Finally, means for electrically powering the lights may be provided. The means may be mechanically operated, such as by mechanically inducing a current in a coiled wire, or by hand-cranking a dynamo in electrical communication with the lights. Thus harmful or undesirable contents may be physically filtered and further irradiated to provide potable water.
