A desalination brine dispersal apparatus and method employ airlift to remove, oxygenate and disperse brine from a desalination apparatus. The apparatus includes a brine removal conduit having a brine inlet that receives brine from the desalination apparatus, a plurality of brine outlets submerged in seawater and one or more air introduction points located at depths below the brine outlets. The supplied air oxygenates and moves brine through the brine removal conduit and outlets via airlift and disperses the brine into seawater away from the brine removal conduit. The apparatus avoids the formation of concentrated, high shear brine plumes and can disperse brine into seawater over a wide area well away from the brine removal conduit.

A filter module for a water dispensing device according to the present disclosure includes a filter housing which has an inflow port and a discharge port, and a plurality of filters which includes a filtration member provided in the filter housing to purify water flowing therein through the inflow port and to supply purified water to the discharge port, and filtering raw water flowing therein from the outside into purified water, and the filter module includes a pre-filter through which raw water passes firstly and in which a first carbon block having a hollow shape is built-in, a hollow fiber membrane (UF membrane) filter through which water passes through the pre-filter passes secondly, a second carbon block having a hollow shape through which water passing through the hollow fiber membrane filter passes thirdly, and an electrostatic adsorption member through which water passing through the second carbon block passes fourthly.

An artificial lung device includes: a housing which is formed in a tubular shape including both end portions closed, includes a blood inflow port and a blood outflow port, and is arranged such that a center axis of the housing is directed in a lateral direction; a hollow fiber body (gas exchanger) which is arranged in the housing and performs gas exchange with respect to blood while the blood flows from the blood inflow port to the blood outflow port; and a straightening frame (gas guide portion) by which a gas having flowed through the gas exchanger by the flow of the blood is guided to the gas exchanger again in the housing.

A submerged offshore reverse osmosis desalination apparatus and method uses product water from the apparatus and an onshore cooler or heat exchanger provide or improve the cooling of a Sea Water Air Conditioning (SWAC) system, power plant, data center, Ocean Thermal Energy Conversion (OTEC) system, or Rankine Cycle heat engine.

An embodiment of this disclosure provides a liquid treatment device, including: a housing 10 having a housing body 16 and a cover body 11, wherein the housing body 16 is open at one end in a length direction and is close at the other end, the cover body 11 is matched with the one end of the housing body 16 for sealing the one end, and the cover body 11 is provided with an inlet 13 for a liquid to flow into the cover body 11; a reverse osmosis membrane unit 20 located in an accommodation space enclosed by the housing body 16 and the cover body 11, the reverse osmosis membrane unit 20 including a reverse osmosis membrane 24 for performing reverse osmosis treatment on the liquid, a collector tube 27 collects a purified liquid obtained by the reverse osmosis treatment, and a support rod 22 supporting the reverse osmosis membrane 24, wherein the reverse osmosis membrane 24 includes a liquid inlet 21 at one end in the length direction; and a filter 30 arranged in the cover body 11 and located between the liquid inlet 21 and the inlet 13 and is used to filter the liquid entering the cover body 11 via the inlet 13, the filtered liquid entering the reverse osmosis membrane 24 via the liquid inlet. According to this disclosure, by providing the filter in the space between the cover body of the liquid treatment device and the support rod, the liquid entering the reverse osmosis membrane may be preprocessed, spaces may be saved, installation is convenient, and cost is relatively low.

A water purifier includes a water purifier body, a filter bracket provided inside the water purifier body, a pump unit provided inside the water purifier body and including a pump connected to a main water purifying filter installed in the filter bracket, and a vibration transmission-preventing unit which, while the main water purifying filter is installed in the filter bracket, ensures the transmission, to the filter bracket and the water purifier body, of vibrations due to the pressure difference between the pump and the main water purifying filter when water is supplied to the main water purifying filter by means of the pump is reduced by a filter vibration-damping member.

A device for the electrodeionization of a sample liquid. The device has an anode chamber having two openings and an anode, a cathode chamber having two openings and a cathode, and a treatment chamber, that is arranged between the anode chamber and the cathode chamber and has two openings and ion exchanger.
