A

Adiabatic Distillation: Adiabatic is defined as "occurring without gain or loss of heat" and distillation is the condensation process where as water vapor is reduced to a liquid. Skywater's patented adiabatic distillation process replicates and augments nature's process of condensation by simulating the dew point, which allows it to make water continuously, even in low humidity conditions. 

Air-to-Water Device:
a machine that makes water from air with some form of air-to-water technology whether it be "freeze and melt", a desiccant system, or water vapor harvesting technology.

Air-to-Water Technology: science to harvest water from the air. Technology that can capture water vapor from the atmosphere to produce water continuously.

Atmosphere: the gaseous envelope surrounding the earth; the air.

Atmospheric Water Generator: (AWG), is a device that extracts water from humid ambient air. Water vapor in the air is condensed  either by cooling the air below its dew point, pressurizing the air, or exposing the air to desiccants. Unlike a dehumidifier, an AWG is designed to render the water potable.

C

Carbon Filter: Carbon filters are most effective at removing chlorine, sediment, and volatile organic compounds (VOCs) from water. They are not effective at removing minerals, salts, and dissolved inorganic compounds. Typical particle sizes that can be removed by carbon filters range from 0.5 to 50 micrometres. The particle size will be used as part of the filter description. The efficacy of a carbon filter is also based upon the flow rate regulation. When the water is allowed to flow through the filter at a slower rate, the contaminants are exposed to the filter media for a longer amount of time.

Condensation: The act or process of reducing a gas or vapor to a liquid or solid form. The transition of atmospheric water vapor into a liquid. 

D

Desiccant: A desiccant is a hygroscopic substance that induces or sustains a state of dryness (desiccation) in its local vicinity. A desiccant is a substance that absorbs water. It is most commonly used to remove humidity, i.e.; silica, rice, or salt.

Desalination: To remove salt. Water is desalinated in order to convert salt water to fresh water so it is suitable for human consumption or irrigation. In the last decade, membrane processes have developed very quickly, and most new facilities use reverse osmosis technology. Membrane processes use semi-permeable membranes and pressure to separate salts from water. Membrane systems typically use less energy than thermal distillation, which has led to a reduction in overall desalination costs over the past decade. Desalination remains energy intensive, however, and future costs will continue to depend on the price of both energy and desalination technology.1

Dew: moisture condensed from the atmosphere, esp. at night, and deposited in the form of small drops upon any cool surface.

Dew Point:
the temperature to which air must be cooled, at a given pressure and water vapor content, for it to reach saturation; the temperature at which dew begins to form.

Distillation:
The separation of one substance from another. The process of evaporation and subsequent condensation as for purification or concentration.

Distilled Water: water from which impurities, as dissolved salts and colloidal particles, have been removed by one or more processes of distillation; chemically pure water.

Drought: An extended period of dry weather and a diminishing water supply to a region.

E

EPA: The U.S. Environmental Protection Agency (EPA or sometimes USEPA) is an agency of the federal government of the United States charged to protect human health and the environment, by writing and enforcing regulations based on laws passed by Congress. The EPA was proposed by President Richard Nixon and began operation on December 2, 1970, when its establishment was passed by Congress, and signed into law by President Nixon, and has since been chiefly responsible for the environmental policy of the United States.[2] It is led by its Administrator, who is appointed by the President of the United States. The EPA is not a Cabinet agency, but the Administrator is normally given cabinet rank. Lisa P. Jackson is the current Administrator. The agency has approximately 18,000 full-time employees.

Evaporation: Matter passed off in vapor

F

FDA: The Food and Drug Administration (FDA or USFDA) is a government agency of the United States Department of Health and Human Services. The FDA is responsible for regulating and supervising the safety of foods, tobacco products, dietary supplements, prescription and non-prescription medication, vaccines, biopharmaceuticals, blood transfusions, medical devices, electromagnetic radiation emitting devices (ERED), veterinary products, and cosmetics. The FDA also enforces other laws, notably Section 361 of the Public Health Service Act and the associated regulations. Many of these regulations are not directly related to food or drugs. These include sanitation requirements on interstate travel and control of disease on products ranging from certain household pets to sperm donation for assisted reproduction.

G

Gallon to Liters: 1 gallon [US, liquid] = 3.785 Liters

H

Hydrologic Cycle: The natural sequence through which water passes into the atmosphere as water vapor, precipitates to Earth in liquid or solid form, and ultimately returns to the atmosphere through evaporation.

I

K

L

LCD Display: On the Skywater 14 the LCD display is on the front panel of the machine with digital information on the machine's current water level, production status, and also will indicate maintenance and repair needs.

Liters to Gallons: 1 liter = 0.264 Gallons

M

N

NGO: Non-government organization.

O

Ozone: is a molecule composed of three atoms of oxygen. Two atoms of oxygen form the basic oxygen molecule--the oxygen we breathe that is essential to life. The third oxygen atom can detach from the ozone molecule, and re-attach to molecules of other substances, thereby altering their chemical composition. It is this ability to react with other substances that forms the basis of manufacturers’ claims.

P

Potable: fit or suitable for drinking

Potable Water:
water that is fit or suitable for drinking. Water of sufficiently high quality that it can be consumed or used without risk of immediate or long term harm.

Psychometric Chart: a graph of the thermodynamic properties of moist air at a constant pressure
curve.

Q

R

Relative humidity: (RH) is the ratio of the mole fraction of water vapor to the mole fraction of saturated moist air at the same temperature and pressure.

S

T

U

UL: Underwriters Laboratories (UL) is a product safety certification standard in the United States. Additionally, UL analyzes drinking and other clean water samples through its drinking water laboratory in South Bend, Indiana and evaluates products for environmental sustainability through its subsidiary, UL Environment.

V

Vapor: a visible exhalation, as fog, mist, steam, smoke, or noxious gas, diffused through or suspended in the air

W

Water vapor: the gaseous state of water or steam.
