Glossary of Water Terms

Soft Water - A condition of the water in which the water contains low levels of dissolved salts or mineral solids.

Ion Exchange - The process in which a salt-water mix is used to exchange ions between the minerals in the water and the resin in a softener to cause the minerals to stick to the resin for backwashing later.

Water Softener - A device used to reduce, or remove minerals from the water or counteract water hardness.

Water Conditioner - A device that counteracts the side effects of scale buildup but does not alter, remove or change the minerals in the water

Resin - A material used in softeners to affect the state of dissolved minerals within the water through nano-technology or ion exchange.

Nanotechnology - A process or technology that works at an atomic, or molecular level, a range between 1 and 100 nanometers, to create a structure, device or system.

Water Filter - A device that absorbs chemical contaminates from your water such as Chlorine, Chloramines and Pesticides.

pH - The measure of alkalinity or acidity of water, in a scale of 0-14. A pH of 7 is considered neutral.

TDS (Total Dissolved Solids) - The total of any particulate material dissolved in water including minerals.

GPG - Grains per gallon is the measurement of hardness in your water expressed in the grains per gallon of water. This number is normally resulted through the calculation of PPM or mG/L divided by 17.1.

mG/L - Milligrams per litre of hardness in water.

PPM - Another method of displaying mG/L, PPM is the same measurement but is expressed as parts per million.

Reverse osmosis is a separation process that uses pressure to force a solvent through a membrane that retains the solute on one side and allows the pure solvent to pass to the other side. More formally, it is the process of forcing a solvent from a region of high solute concentration through a membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure. This is the reverse of the normal osmosis process, which is the natural movement of solvent from an area of low solute concentration, through a membrane, to an area of high solute concentration when no external pressure is applied. The membrane here is semi permeable, meaning it allows the passage of solvent but not of solute.-wikipedia

Magnetic water softening-is a process in which high energy electrical fields surround a water pipe and as water flows through it, the elements (calcium and magnesium) become suspended in the water and loose their ability to stick to things. This process is temporary.

Compare Water Softeners

Water softeners do not remove contaminants, such as chlorine, chloramines, THM's, VOC's, SOC's, they are designed to address hard water issues.
It is recommended that a whole house water filter be coupled with any water softener.
