Water Treatment

WI-05 Water Treatment

TermDefinition
preoxidation a “prep step” where ozone or other chemicals are added to water to cut down on smells and junk, making later cleaning steps work better
ozone a super-powered version of oxygen with three atoms (O₃). It breaks down unwanted stuff in water really fast
organic materials bits that come from living things—like leaves, tiny organisms, or pollution from people
coagulation special chemicals make dirt particles in water stick together into bigger pieces, kind of like magnets pulling them in
flocculation when the water is gently mixed so those small clumps join up into bigger ones, called flocs
sedimentation water sits in a tank and the heavy clumps (flocs) sink to the bottom, leaving the clearer water on top
filtration water is strained through layers of sand, coal, or other materials, like a giant filter, to trap what’s still floating around
disinfection water is treated with things like chlorine or UV light to kill germs and viruses, making it safe to drink
