An automatic rainwater collection system, with a high degree of autonomy and sensitivity, which allows the collection and use of rainwater, in open spaces, areas of difficult access and/or lacking of water extraction systems, as well as in domestic spaces such as gardens or roofs, without additional adaptations for its use and which works with solar energy. The automatic rainwater collection system is conformed by: a flower-shaped obturable rainwater receiving element, which comprises: a plurality of internal petals and a plurality of external petals that can be opened or closed in an automated manner, a sensor with high sensitivity to droplet impacts and/or relative humidity, which is operatively connected to a motor to control the opening and closing of the plurality of petals of the rainwater receiving element; a support frame, which functions as a support for the obturable rainwater receiving element and as a water storage media; a modular system for filtering water, connected to said central media of water accumulation, which comprises a plurality of filtering modules, which provide different filtering options depending on the quantity and combination thereof in order to obtain different qualities of water for use in several activities; and a water storage media, which further functions as base and support of the collection system.

A water sanitization cap for covering a bottle is provided. The cap may include an ultraviolet-C (“UV-C”) light emitting diode (“LED”) housing and a shell. The shell may be adjacent to a portion of the housing. The cap may also include a waterproof compartment formed within the interior of the housing. The waterproof compartment may include one wall formed at least in part from a transparent material. The cap may include a UV-C LED. The UV-C LED may be fixed within the waterproof compartment, proximal to one end of the UV-C LED housing and oriented to shine light through the transparent material. The cap may include a sensor that when activated, applies a voltage to the UV-C LED to cause the UV-C LED to emit light. The cap may include a cartridge cage that can hold a cartridge. The cartridge cage may be removably attachable to an inner surface of the shell. The waterproof compartment wall may be positioned relative to the cartridge cage such that the UV-C LED, in use, treats water within the bottle before the water flows through the cartridge cage.

Disclosed herein are systems and methods for purifying aqueous solutions. For example, disclosed herein are flexible membrane distillation systems comprising one or more stages stacked on top of each other, wherein each stage comprises: a feedwater layer; a membrane distillation layer; a distillate layer; and a thermally conductive layer. The systems further comprise substantially impermeable top surface, bottom surface, and perimeter. Each feedwater layer is independently receives a portion of a contaminated aqueous solution (a feed solution). Each feedwater layer further receives heat from a heat source to distill at least a portion of the feed solution through the membrane distillation layer, thereby producing a distillate in the distillate layer. Distilling said portion of the feed solution through the membrane distillation layer purifies said portion of the feed solution to produce a purified aqueous solution, which is condensed in the distillate layer to form a condensate.

A water purifying and desalination system includes solar concentrators that receive a sunlight and direct the sunlight toward a collection element. The collection element absorbs and converts a solar radiation into thermal energy. A superheater tube enclosed by the heat collection element controls volume flow that partially fills the superheater tube with processed ocean water, which allows steam to escape into a portion of the superheater tube that generates electricity and additional processed ocean water.

A heat power management system is disclosed for an alternating current (AC) power controller for use with portable reverse osmosis water purification systems requiring precise control of a heating action for an internal water heater coupled with energy savings and the reduction of AC line disturbances. The heat power management system is designed to operate with various international electrical systems while protecting such system from excessive current draws.

A heating system for use in the solar powered heating of water. In one embodiment, the heating system is used in conjunction with a solar water farm to desalinate water. The water farm can be utilized on a variety of scales and can be applied to agricultural farms for large scale reclamation of deserts.

A portable water treatment system comprising a water processing unit that automatically determines whether the system is connected to a pressurized water source or not. If an unpressurized source is detected, the system activates a pump to ensure that the water flows through the system at a pressure level to remove particulates and ensure the ultraviolet (UV) light is effective at neutralizing viruses and bacteria. If the water source is pressurized, the pump is deactivated and the water flows through the system under the pressure of the pressurized source. The system uses a failsafe mechanism to 1) ensure that water cannot flow through the water treatment unit if the UV light chamber is not powered and 2) ensure the user can know that the UV light is in fact functioning through the use of an indicator.

A device for generating hydrogen gas, treated water, and metal-containing nanoparticles. The device includes a vessel containing an electrolyte solution having a preferably iron anode and a preferably copper cathode. A renewable energy source is connected to the anode and the cathode. A valve for disbursing the hydrogen is connected to the hydrogen chamber.

Embodiments of the present disclosure include systems and methods for enhancing the performance and efficiency of separation processes. The methods include flowing a fluid through a processing zone defined by an antiferromagnetic portion of a conduit and, as the fluid flows through the processing zone, exposing the fluid to a magnetic field produced by oscillating electromagnetic waves, wherein the direction of the magnetic field is generally counter to the direction in which the fluid is flowing. The systems include magnetic treatment units, separation systems, and the like.

A system for agricultural irrigation water oxygenation for enriching soil oxygen level comprises a source of compressed oxygen (and not compressed air) coupled to a water line feeding an irrigation system, such as a drip irrigation system. The coupling system may include a pressure sensor for measuring the pressure in the water line, a solenoid safety valve, a control valve, a flow meter and a controller that controls the flow of oxygen from the source of compressed liquid oxygen to the water line using the components of the coupling system, without using a special cavitation valve and using off-the-shelf components while achieving the same benefits as a system incorporating the special cavitation valve.
