Glossary Of Water Treatment Industry Terms . . ."O"
odors - Are self-descriptive.
Odors are sometimes transmitted to the sample by the shipping container
when it is not a standard Culligan sample bottle.
operating pressure- The
range of pressure, usually expressed in pounds per square inch, over
which a water conditioning device or water system is designed to function.
organic matter- Substances
of or derived from plant or animal matter. Organic matter is characterized
by its carbon-hydrogen structure.
osmosis - A process of
diffusion of a solvent such as water through a semipermeable membranae
which will transmit the solvent but impede most dissolved substances.
The normal flow of solvent is from the dilute solution to the concentrated
solution in an attempt to bring the solutions on both sides of the membranae
to equilibrium. (See equilibrium, reverse osmosis.)
oxidation - A chemical
process in which electrons are removed from an atom, ion, or compound;
causing the substance's valence to increase. The addition of oxygen
is a specific form of oxidation; combustion is an extremely rapid form
of oxidation, while the rusting of iron is a slow form. Whenever oxidation
occurs, an offsetting reduction reaction must occur. (See reduction.)
ozone - An unstable form of oxygen (O3), which can be generated by an electrical discharge through air or regular oxygen. It is a strong oxidizing agent and has been used in water conditioning as a disinfectant.
