Infection Control Flashcards
exposure of milk to progressively higher temperatures
pasteurization
use of chemicals or heat to destroy all life
sterilization
use of chemicals to destroy most pathogens
disinfection
allowing water to pass through materials with pores of different sizes
filtration
use of aluminum to precipitate material from water
flocculation
allows the precipitate to settle out
sedimentation
addition of anaerobic bacteria to aid in the break down organic material
sludge digestion
allowing water to pass through sand which removes anaerobic bacteria
sand filtration
bubbling oxygen through water to kill anaerobic bacteria
aeration
adding chlorine which kills all remaining bacteria
chlorination
inoculation with a substance to establish resistance against specific dz
