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 water filtering pitcher with a pitcher with a top, a base and an inner wall surface extending between the top and the base to define an internal volume. A filter adapter is positioned within the internal volume of the pitcher, configured to couple to a water filter, and movable between a first position closer to the base and a second position closer to the top. At least one bias member configured to bias the filter upward is positioned between the filter adapter and the pitcher base. When a water filter is received through the top of the pitcher to the filter adapter and water is filtered from above the filter adapter through the water filter and into the base of the pitcher, the at least one bias member biases the filter adapter and water filter from the first position toward the second position.

A stand-alone toilet system is powered by photovoltaic cells to operate a dehumidifier from which water is extracted from the atmosphere by dehumidification and used for flushing; an electronic compressor is situated in the toilet tank to compress air which is used with water in the flush cycle; a motorized or hydraulic hinge is utilized to open and close a toilet cover automatically which can be locked in place by electromagnet means to create an airtight seal in the closed position; a heating element and a UV lamp are situated inside the “treatment facility” of the toilet system to evaporate liquid and sanitize waste content therein respectively.

The present invention relates to a portable liquid purifier for purifying liquid contained in the purifier using an ozone flow that passes through the liquid. The invention comprises a container, an ozone generator built into the base of the container, a blower extending from the ozone generator and provided with blow holes in the lower part of the container, and a standalone power source that does not have to be connected to the network during the operation of the purifier in order to power the ozone generator and the blower. The invention can be used to purify drinks in any location, while camping, hiking, travelling in exotic countries, etc., owing to the bactericidal, viricidal, and fungicidal properties of the ozone, as well as offering the unexpected or additional advantage of performing disinfection in the same container into which the ozone generator is built.

A portable drinking water generator includes a micro gas pump, a micro condenser module, and a micro liquid pump. The portable drinking water generator utilizes the micro gas pump to draw air and transmit the purified air to the micro condenser module. The water in the air is condensed into liquid water by the micro condenser module. Afterwards, the liquid water is collected and transported to a water purification module by the micro liquid pump. The liquid water is filtered by the water purification module and becomes drinkable drinking water. Therefore, the portable drinking water generator can achieve generating drinking water.

A system for wastewater treatment includes a container placeable in the fluid within a wastewater treatment vessel. The container comprises an inlet into which fluid from the treatment vessel can flow. In operation, compressed air is provided to aerate fluid within the container and vented from the container in such a way that fluid in the vessel external to the container does not receive aeration. Substrate within the container provides biomedia for treating wastewater. The user controls the operation of a pump that transports fluid from inside the container into fluid in the vessel external to the container. Concomitantly, fluid from outside the container flows in though the container's inlet. Thereby, the system continuously treats wastewater with aeration, intermixing treated and untreated wastewater.

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.

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.
