Primary disinfection means the adding of an acceptable primary disinfectant or ultraviolet light irradiation during the treatment process to provide adequate levels of inactivation of bacteria and pathogens. The effectiveness is measured through "CT" values, and the "Total Inactivation Ratio[.]," and the ultraviolet light dose. Acceptable primary disinfectants are, chlorine, ozone, ultraviolet light, and chlorine dioxide (see also "CT" and "CT99.9").

  • Disinfect means to eliminate virtually all germs from inanimate surfaces through the use of chemicals or physical agents (e.g., heat). In the child care environment, a solution of ¼ cup household liquid chlorine bleach added to one gallon of water (or one tablespoon bleach to one quart of water) and prepared fresh daily is an effective disinfectant for environmental surfaces and other objects. A weaker solution of 1 tablespoon bleach to 1 gallon of cool water is effective for use on toys, eating utensils, etc. Commercial products may also be used.

  • Membrane filtration means a pressure or vacuum driven separation process in which particulate matter larger than one micrometer is rejected by an engineered barrier, primarily through a size exclusion mechanism, and which has a measurable removal efficiency of a target organism that can be verified through the application of a direct integrity test. This definition includes the common membrane technologies of microfiltration, ultrafiltration, nanofiltration, and reverse osmosis.

  • Residual disinfectant concentration (“C” in CT calculations) means the concentration of disinfectant measured in mg/l in a representative sample of water.

  • Diatomaceous earth filtration means a process resulting in substantial particulate removal in which a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and while the water is filtered by passing through the cake on the septum, additional filter media known as body feed is continuously added to the feed water to maintain the permeability of the filter cake.
