A method and system for treating and purifying saltwater contaminated by volatile compounds. The saltwater is evaporated resulting in a gas composed of water vapor and gaseous volatile compounds. The gas is condensed into a condensate containing the contaminated volatile compounds which is biologically treated to remove the volatile compounds thereby producing purified water. The latent heat released by condensing is used to evaporate the purified water into the atmosphere in an energy efficient manner.

A modular element for making reverse osmosis filtering devices includes: at least one first container and a second container, each of which is provided with a tubular lateral wall, with a bottom plate which closes a first axial end of said lateral wall, with an inlet, with a first outlet and with a second outlet, the first and second containers being arranged so that the respective lateral walls are arranged adjacent and have mutually parallel central axes, and a scavenging duct which connects the second outlet of the first container with the inlet of the second container, the first container, the second container and the scavenging duct are obtained as a single monolithic body.

The single-hand-operable micro water purifier of the present application relates to a micro water filter, especially a micro water purifier which can filter water by means of pressuring. It consists of a micro filter device and a raw water pressurizing device. The micro filter device consists of a filter cylinder body, a filter water inlet, and a filter water outlet and a filter material assembly located in the filter cylinder body. The raw water pressurizing device consists of a pressurizing device water inlet, a pressurizing device main body, and a pressurizing device water outlet. The present application can promote the raw water to enter the filter device for performing the filtration to obtain the clean water, by using a single hand to operate, which not only brings convenience to the user, but also saves labor and improves the use efficiency.

Provided herein are systems and methods for cleaning surface water streams. More specifically, surface water is cleaned using the systems and methods described herein wherein the surface water cleaning system comprises sequential aligned basins which are configured to direct water flow through one or a series of filter media such that the filtered water stream is reduced in organic chemicals and/or particles.

A universal water purification system and method that can desalinate salt water or just filter fresh water. Preferably, the system is portable and relatively lightweight and provides for emergency or recreational safe power and water accessibility. The components of the system can be installed on an aluminum frame and preferably include one or more of a waterproof front control panel, four pre-filters, a reverse osmosis membrane or graphene filter, or electrical process of separating chloride ions from water, ultraviolet (UV) LED lamp, ultrasonic frequency generator, chlorinator or disinfecting gas infusion, a high pressure reverse osmosis (RO) pump, or other desalination process and a low pressure water supplying pump, an electro valve preferably with a manual override in case of power loss and can be activated based on the content of total dissolved solids of incoming water. The system may be removably inserted into a suitcase that can be carried by an individual, or housed in a frame with wheels.

Systems and methods for use in extracting oil from solid plant-based materials are described. The systems and methods use an electrolyzed carrier fluid made from a hydroxide brine for contacting with plant-based material to thereby separate oil from solid plant particulate. The electrolyzed carrier fluid can have a reductive oxidation-reduction-potential (ORP) of −700 mV or more, such as in the range of from about −900 mV to about −1000 mV.

A polymer/activated carbon composite made up of a branched polyethylenimine and magnetic cores involving Fe.sub.3O.sub.4 disposed activated carbon. The magnetic cores have activated carbonyl groups on the surface. A process for removing organic dyes, such as methyl red, as well as heavy metal ions from a polluted aqueous solution or an industrial wastewater utilizing the composite is introduced. A method of synthesizing the polymer/activated carbon composites is also specified.

The embodiments disclose a method including processing and treating at least one water source supply for mixing with humic acid and fulvic acid, chopping and pulverizing at least one humate source, mixing the chopped and pulverized at least one humate source with the processed and treated at least one water source supply, processing the chopped and pulverized at least one humate source and the processed and treated at least one water source supply for separating, segregating, and suspending fulvic acid and humic acid molecules from the at least one humate source, storing the fulvic acid and humic acid molecules in a fresh quantity of the treated water source supply, adjusting the pH level of the stored fulvic acid and humic acid, and creating at least one or more beverage product for human consumption using the fulvic acid and humic acid molecule ingredients and other ingredients including vitamins, flavorings and additives.

Illustrative configurations of a pet hydration system and methods are disclosed. The pet hydration system includes a bowl section configured to temporarily store water therein. In one configuration, a hydrogen-generation assembly is positioned in the bowl section. The hydrogen-generation assembly generates and introduces hydrogen into the water temporarily stored in the bowl section. In other configurations, methods related to pet hydration are also disclosed.

A water purifying apparatus including a head having a water inlet portion and a water outlet portion; a shaft provided in the head and rotatably mounted between the water inlet portion and the water outlet portion; a bypass flow path passing through a circumference of the shaft, and communicating the water inlet portion with the water outlet portion according to rotation of the shaft; a filter detachably mounted to the head, and having a filter inserting portion in which the shaft is inserted when being mounted on the head; and a filtering flow path in which an inlet port and an outlet port are formed on the circumference of the shaft in a direction intersecting the bypass flow path, and communicated between the filter, the water inlet portion and the water outlet portion with each other according to the rotation of the shaft.
