Science Again Unit 1 Flashcards
What are the three categories of water contaminents?
Biological, Chemical, Physical
What is the definition of biological contaminents
They are both visible & miccroscopi
Definition of Chemical contaminnents
dissolved substances that come from natural proccesses or human activity
Definitions of physical contaminents
All materials that do not dissolve in water
What Are the 8 sources of water contamination
Leakage, Urban Runoff, Landfills, Mining, Pesticides, Industrial Waste, Radioactive Waste, animal waste/fertilizer
contamination causes leakage
Chemical & Wastewater storage causes frequent leaks
Urban Runoff contamination causes
A use of chemicals, oil and gasoline contributes
Landfills contamination causes
Plastics, printer ink, medication battery acids
MIning contamination causes
Fracking from the mining industry
Fracking Definition
Waste
Pesticides contamination causes
The chemicals can cause cancer & Death (DDT)
Industrial Waste contamination causes
Industrial waste is waste in factories cooperations
Radioactive waste contamination causes
When water is polluted with radiation it kills fish almost immediately
Animal Waste/Fertilizer contamination causes
The Buildup of ammonia & Nitrates lead to nutrient pollution
What are the 4 steps of Water treatment Plants
Coagulation & Flocculation, Sedimentation, Filtration, Disinfection
Definition of Coagulation & Flocculation
When chemicals called coagulants (Flocc Particles) mix with water in flocculation basin
What is removed in Coagulation and Flocculation
Flocc Particles, sludge
Definition of Sedimentation
Sediments fall to the bottom
What is removed in sedimentation
Sand Bacteria & Materials
Filtration definition
Sand filter, and active carbon
What does active carbon do
Improves taste and odor
What is removed in filtration
Bacteria
