Disclosed are an integrated composite filter cartridge (200) and a water purifying system (300) having same. The integrated composite filter cartridge (200) comprises: an outer shell (20), wherein a chamber (21) is defined in the outer shell (20), and the outer shell (20) is provided with a raw water inlet (22), a pre-treated water outlet (23), a pre-treated water inlet (24), a purified water outlet (25) and a waste water outlet (26) which are in communication with the chamber (21); a pre-treatment filter cartridge (100); a central pipe (30); a filter membrane (40); and a control member, which is connected to the pre-treated water outlet (23) and the pre-treated water inlet (24). When the integrated composite filter cartridge (200) is used for the first time, the control member switches on the raw water inlet (22) and the pre-treated water outlet (23) and switches off the pre-treated water inlet (24).

A portable water purifying apparatus, including a shell and a hollow, elongated chamber. The apparatus includes a first opening that feeds into this chamber, through which the user draws contaminated water into the chamber, and a second opening for removing purified water from the chamber. Purification of the contaminated water drawn into the apparatus is effected by water purification media, which may include an ultrafiltration membrane; a halogenated resin; and granulated, activated carbon. The apparatus may also include one or more cleanable, removable, replaceable cartridges for containing the water purification media.

Integrated tidal desalination system that harnesses tidal power to produce drinkable water through a mechanically linked or direct drive integrated tidal turbine (ITT) and centrifugal reverse osmosis (CRO) system. The ITT-CRO system eliminates conversion losses in the power take-off unit by eliminating the need for electrical energy conversion. The ITT-CRO system is modelled, and the model used for control, and predictive maintenance.

A control method of a control system for controlling water purification module for processing water on two sides of a reverse osmosis membrane. The control system has a water purification module and a control module. The water purification module has a preliminary filter and a reverse osmosis filter. The control module regularly controls the purification and the drainage of the water purification module, and solves the problem that the TDS value of the water on both sides of the reverse osmosis membrane is too high after the water purifier is on standby for a period of time. The control system regularly drains high concentration water on both sides of the reverse osmosis membrane to improve water purification efficiency.

A desalination brine dispersal system for a submerged seawater desalination apparatus, the seawater desalination apparatus having submerged components comprising distillation equipment, evaporation equipment or separation membranes; one or more pumps; and a brine removal conduit. The brine removal conduit receives brine from the desalination apparatus, and has an upwardly-directed length and at least one fluid outlet that is at a lesser depth than the desalination apparatus components. They system disperses brine into seawater without causing pooling of brine on the seafloor, can avoid 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.

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.

The Thermodesalination Device has the capability of employing reverse osmosis via a specialized desalination system. This specialized desalination system is integrated into the upper portion of a steam turbine generator that separates seawater into fresh water and concentrated brine, for preferred allocation. The disclosed desalination device includes a reverse osmosis (RO) membrane comprising a solute side and a solvent side and vanes configured to strengthen a sheer of the RO membrane. The disclosure also includes a steam turbine configured to superheat a saltwater input and create a pressurized and superheated saltwater output on the solute side of the RO membrane. The disclosure yet includes a freezer configured to freeze a brine output from the solute side of the RO membrane into the shape of salt crystals.

A method, an apparatus and a controller for pre-treatment of seawater is described. The apparatus controls a supply of a seawater stream to a filtration unit, which outputs a first filtered stream based on the supply of the seawater stream. The method further includes controlling a supply of the first filtered stream to a graphene-based ultrafiltration unit. The graphene-based ultrafiltration unit outputs a second filtered stream based on the supply of the first filtered stream. The graphene-based ultrafiltration unit comprises graphene oxide membranes. The method further includes controlling a supply of the second filtered stream to a seawater reverse osmosis (SWRO) membrane unit. The method further includes controlling an outlet of the SWRO membrane unit to output a desalinated stream based on the supply of the second filtered stream.
