Disclosed are methods, systems, and apparatuses for purifying liquids. One illustrative method includes generating an aerosol from a contaminated liquid. The illustrative method also includes generating a vapor from the aerosol by applying a negative pressure to the aerosol. The illustrative method further includes separating at least one type of contaminant particle from the vapor and converting the vapor into a liquid.

An atomization device includes a pair of counter-rotating rollers, a fluid source configured to coat at least one of the rollers in a feed fluid, and a baffle unit. The counter-rotation of the rollers stretches the feed fluid into a fluid filament between the two diverging surfaces of the rollers. The stretched fluid filaments break into a plurality of droplets at a capillary break-up point of the feed fluid. The baffle unit introduces a baffle fluid within the interior of the device and the baffle fluid transports formed droplets of the feed fluid from the atomization device. Excess or misguided atomized fluid droplets are collected by the baffle unit and are recycled back into the device for use in later atomization processes. The variation of atomization device parameters allows for the selection of droplets having desired physical parameters.

Provided is a humidification and air cleaning apparatus. The humidification and cleaning apparatus includes: a water tank storing water; an air wash inlet disposed in the water tank and communicating the inside of the water tank with the outside thereof; a water tank humidification medium covering the air wash inlet, formed of a material absorbing water, and humidifying air passing the air wash inlet; a watering housing disposed inside the water tank, suctioning water of the water tank thereinto, pumping the suctioned water to an upper side when rotating, and spraying the pumped water; and a watering motor providing a torque to the watering housing. Here, the water tank humidification medium is spaced from water stored in the water tank and is wetted by water sprayed from the watering unit.

Provided is a humidification and air cleaning apparatus including a water tank storing water; an air wash inlet formed at the water tank and communicating the inside and the outside of the water tank and a water tank humidification medium formed of a material for absorbing water and providing humidification on air passing through the air wash inlet. The water tank humidification medium is located inside the air wash inlet to cover the air wash inlet.

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes: a water tank storing water; a visual body forming at least a portion of the water tank and formed of a transparent material; a top cover assembly disposed over the water tank and including a water supply flow passage disposed therein to supply water into the water tank; a watering housing disposed inside the water tank and rotating inside the water tank; and a watering motor rotating the watering housing. Here, when the watering housing rotates, water supplied to the water supply flow passage drops on the watering housing to be scattered.

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes a water tank storing water; a top cover assembly disposed over the water tank and including a water supply flow passage disposed therein to supply water into the water tank; a reservoir disposed in the top cover assembly, disposed on the water supply flow passage, and storing supplied water; and a watering housing disposed inside the water tank and receiving a torque from a watering motor so as to be rotatable. Here, water supplied through the water supply flow passage is stored in the reservoir, and then drops on an upper part of the watering housing.

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes a water tank storing water; a visual body forming at least a portion of the water tank and formed of a transparent material; a watering housing disposed in the water tank, drawing water stored in the water tank to pump water to an upper side, and spraying the pumped water; a nozzle disposed in the watering housing and spraying the pumped water; and a watering motor rotating the watering housing. Here, when the watering housing rotates, water sprayed from the nozzle forms at least one spray line on an inner side surface of the visual body.

Aspects and embodiments of the invention provide methods and systems of infusing liquid into gas. One method according to an aspect of the invention comprises: filling a chamber having a fixed volume with a first gas content at a first pressure: subjecting the gas content to a high-pressure injection of liquid content into the chamber at a second pressure, wherein, the second pressure is higher than a predetermined pressure saturation requirement of the liquid content. One system according to an aspect of the invention comprises: a cylinder (200) comprising at least one chamber of fixed internal volume and having a first end (200a) and a second end (200b); a floating piston (202) arranged within the internal volume of the chamber; a first gas input port that is selectively connected to the first end of the chamber; a second gas input port that is selectively connected to the second end of the chamber; a first liquid input port that is selectively connected to the first end of the chamber; a second liquid input port that is selectively connected to the second end of the chamber; a first exhaust port that is selectively connected to the first end of the chamber; and a second exhaust port that is selectively connected to the second end of the chamber.
