Systems for treating water, e.g., mobile deionization systems, are disclosed. The system includes a system inlet connectable to a source of water to be treated; a water distribution manifold connected to the system inlet and including a plurality of valves structured and arranged to provide a configurable flow path along the water distribution manifold; a plurality of water treatment vessels each having an inlet and an outlet connected to the water distribution manifold; and a system outlet connected to the outlet of a last of the plurality of water treatment vessels. The plurality of valves are selectively operable to provide for sections of the water distribution manifold to switch between flowing water into one or more of the plurality of water treatment vessels or receiving water from the one or more of the plurality of water treatment vessels. Methods of treating water using the systems are also disclosed.

Processes and systems suitable for purifying or otherwise treating liquids to remove contaminants therein, including but not limited to contaminated water, to permit reclaiming, recycling, and reuse of the liquids. Such a process and system entails the use of a cascading distillation system that evaporates a liquid from the feedstock and then condenses and collects a more purified form of the liquid. The cascading distillation system can be operated to selectively process the feedstock through any of a series of vessels at which different amounts and/or contaminants may be removed from the feedstock.

The present invention relates to systems and methods for cleaning materials, such as flooring and upholstery. In some cases, the systems and methods use an electrolytic cell to electrolyze a solution comprising sodium carbonate, sodium bicarbonate, sodium acetate, sodium percarbonate, potassium carbonate, potassium bicarbonate, and/or any other suitable chemical to generate electrolyzed alkaline water and/or electrolyzed oxidizing water. In some cases, the cell comprises a recirculation loop that recirculates anolyte through an anode compartment of the cell. In some cases, the cell further comprises a senor and a processor, where the processor is configured to automatically change an operation of the cell, based on a reading from the sensor. In some cases, a fluid flows past a magnet before entering the cell.

In some additional cases, fluid from the cell is conditioned by being split into multiple conduits that run in proximity to each other. Additional implementations are described.

A sewage treatment machine comprising: a closed container inside which the liquid to be treated is brought to boil; a vacuum-generating apparatus, which is adapted to maintain the inside of the closed container at a given pressure having a value lower than the environmental/external pressure; a heat-pump assembly which is associated to the closed container so as to be able to transfer heat to the liquid present on the bottom of the closed container, thus to bring said liquid to boil, and simultaneously remove heat from the vapours that reach the top of the closed container, thus to condense the vapour and obtain a distilled liquid, and which contains a refrigerant fluid comprising one or more gases of the family of the hydrofluoroolefins in a percentage greater than 3%.

A cost-effective system and method dissolves gas, such as oxygen, into water in a manner that prevents gas bubble carry over by using a bubble capture system (BCS). The method further eliminates or minimizes turbulence at the suction and discharge of a pump using an energy dissipation header (EDH). The BCS can create a top-down flow that permits bubbles to rise faster than the velocity of the downward flow of water. The EDH can use a pipe design, such as a slotted pipe design, that permits a maximum system water flow. The technology can be applied to water bodies to mitigate eutrophication and may also be applicable in other fields, such as wastewater lift stations, fish farms, oil and gas industry, tidal applications with low flushing rates, and winter under ice oxygenation to prevent fish kills.

A wastewater processing method includes introducing wastewater into an upper region of a chamber. The chamber remains at substantially atmospheric pressure. A portion of the wastewater in the chamber is vaporized. Flame is introduced into the chamber and provides for the ignition of a volatile organic compound. The vaporized portion of the wastewater is vented to the atmosphere.

An evaporation system for spray evaporating undesired water comprising: a first pump, a container comprising a sump, a second pump, a spray manifold comprising a spray nozzle, a packing system disposed within the container, a third pump, and an air system comprising an air blower and an air preheater is disclosed. An outlet of a water inlet is connected to an inlet of the first pump. A first portion of a ceiling of the container is constituted by a demister element such that the first portion of the ceiling is entirely configured as an outlet for evaporated water. A second portion of the ceiling is adjacent to an upper edge of a wall of the container. An outlet of the first pump is connected to an inlet of the container. An inlet of a draw line is disposed in the sump; and an outlet of the draw line is connected to an inlet of the second pump. An outlet of the second pump is connected to an inlet of the spray manifold. The spray nozzle discharges water droplets onto the packing system. An inlet of the third pump is connected to an outlet of the sump. An outlet of the third pump is connected to a discharge outlet. The air system is disposed through the wall of the container; and the air system discharges air flow counter to and/or crossways to the water droplets from the spray nozzle. A method of using the evaporation system is also disclosed.

Per- and polyfluoroalkyl substances (PFAS) are destroyed by oxidation in supercritical conditions. PFAS in water can be concentrated and prepared for destruction in a pretreatment phase. Following annihilation of the PFAS in supercritical conditions to levels below 5 parts per trillion (ppt), the water effluent can be used to recover heat, returned to sub-critical conditions, and then released back into the environment.

An emitter apparatus is mounted on a marine structure powered by wind or marine hydrokinetic energy to disperse a carbon dioxide sorbent such as sodium hydroxide. The sorbent can be generated by reverse osmosis of seawater with electrolysis of the brine, or delivered from an external supply. Suitable marine structures include offshore wind turbines, marine hydrokinetic generators, offshore oil platforms, merchant vessels, and other fixed and mobile structures. Effective capture is made by dispersing a fine mist or fog of aqueous sorbent from nozzles with a particle size from a nozzle of less than 100 microns. The sorbent reacts with atmospheric carbon dioxide forming carbonates and bicarbonates, which drift and fall to the ocean surface, reducing surface acidity and capturing additional atmospheric carbon dioxide via absorption at the local ocean surface. The resulting carbonates sink to the ocean floor and are there sequestered.
