A positively-charged ion, which has fewer electrons than protons, due to its attraction to cathodes.Saturday, December 06, 2008 10:04 PM
A general term used to describe the behavior of voids or bubbles in a liquid. Cavitation is usually divided into two classes of behavior: inertial (or transient) cavitation and non-inertial cavitation. Inertial cavitation is the process where a void or bubble in a liquid rapidly collapses, producing a shock wave. Such cavitation often occurs in pumps and impellers Non-inertial cavitation is the process where a bubble in a fluid is forced to oscillate in size or shape due to some form of energy input, such as an acoustic field. Such cavitation can be observed in pumps.

- CENTRIFUGAL PUMP
A type of kinetic energy pump using centrifugal force(slinging motion) to accomplish it's work. A pump containing a rotation impeller or rotating vanes mounted on a shaft in a casing and turned by a power source. The rotating impeller uses centrifugal force to deliver water in a steady stream.

A chelating agent is a water soluble molecule that can bond tightly with metal ions, keeping them from coming out of suspension and depositing their stains and scale onto pool surfaces and equipment. Similar to sequestering agents, chelators are found in such products as "Resist" and "Sea-Klear."Saturday, December 06, 2008 10:11 PM
A naturally occurring polymer found in the shells of crabs and lobsters. Contained in the product "Sea-Klear." Chitin acts as a coagulant and flocculent for oils, metals, and organic materials.

The chlorine molecule is strongly attracted to nitrogen and ammonia. When these two combine they form a chloramine, which are undesirable, foul smelling, space taking, compounds that require shocking the pool water to get rid of.Saturday, December 06, 2008 10:14 PM
Devices which allow for the safe controlled introduction of chlorine into the water.
