摘要： An energy-saving water purifying system has a tube, two pistons, a movable component, a pump, and a filter. The two pistons are mounted in the tube. The movable component is moveably mounted between two block portions of the tube. Two magnetic elements are mounted on the movable component and repulse magnetic elements of the two pistons. The movable component selectively blocks one of two wastewater entrances of the tube. An outlet of the pump is connected to two check valves of the two inlets in parallel. An inlet of the filter is connected to two check valves of the two outlets in parallel. A wastewater exit of the filter is connected to the two wastewater entrances of the tube in parallel. The water purifying system is switched by magnetic force so that the structure is simplified, energy is saved, and cost and fault rate are decreased.

摘要： An apparatus for increasing gas components in a fluid uses a controller connected to a network and client device for remote control of fluid flow rates, magnet field intensity, and pressure of fluid based on preset parameters. Conductive wire coiled around a magnet fluid treatment device generates a bidirectional magnetic flux to magnetically treat fluid in the conduit at an entry pressure. A variable frequency generator energizes the wire creating magnetic flux lines to pass through the fluid flow conduit. A gas injector receives fluid at the gas injector entry pressure and lowers the gas injector entry pressure of the fluid to a gas injector discharge pressure. A treatment chamber receives the fluid at a treatment chamber entry pressure and lowers the treatment chamber entry pressure to a treatment chamber discharge pressure. The apparatus causes absorption of increased gas component into the fluid by from 10% to at least 500%.

摘要： A gas infusion waste water treatment facility having an apparatus for increasing gas components in a fluid uses a controller connected to a network and client device for remote control of fluid flow rates, magnet field intensity, and pressure of fluid based on preset parameters. Conductive wire coiled around a magnet fluid treatment device generates a bidirectional magnetic flux to magnetically treat fluid in the conduit at an entry pressure. The facility creates absorption of increased gas concentration containing an oxygen atom into the fluid from 10% to at least 500%.

摘要： The disclosed subject matter relates to an automated CFF/TFF system that provides the operations of system treatment with a system treatment solution(such as buffer) and filtration of a solution (e.g., a biofluid) can be accomplished in succession without having to re-configure the system (such as re-routing the fluid conduits) that could compromise the integrity of the system. As a result, there will be reduced contamination risk, reduced volume of buffer required and will save time for the filtration process.

摘要： A device for sea water desalination and power generation, including: a tidal current turbine, a coupling, a revolving shaft, a booster pump, and a body. The body includes a chamber, a divider, and an end cover. The divider and the end cover are in fixed connection to the body, and the divider divides the chamber into a closed pumping chamber and a closed desalination and power generation chamber. The booster pump is disposed in the pumping chamber and is driven by the revolving shaft. The tidal current turbine is connected to the revolving shaft via the coupling. The desalination and power generation chamber includes a seawater pretreatment device, a seawater desalinating unit including an unsteady reverse osmosis membrane, a flow battery, and a controller. The booster pump is connected to the seawater pretreatment device via an inlet tube, and is connected to the seawater desalinating unit via an outlet tube.
