A
  1. Screening
  2. Aeration
  3. pH Correction
  4. Coagulation
  5. Sedimentation
  6. Disinfection
27
Q

Step 1 of Water Treatment; Screening

Silly Alligators Pee Constantly Sadly Doe

A

Removal of large floating objects through a large rotating screen

28
Q

Step 2 of Water Treatment; Aeration

Silly Alligators Pee Constantly Sadly Doe

A

Using pressure to force oxygen gas into the water to remove the bad smell and taste

29
Q

Step 3 of Water Treatment; pH Correction

Silly Alligators Pee Constantly Sadly Doe

A

Add chemicals so that water is neutral, helps with coagulation

30
Q

Step 4 of Water Treatment; Coagulation

Silly Alligators Pee Constantly Sadly Doe

A

Use alum to clump together solids into larger solids so they sink to the bottom of the tank

31
Q

Step 5 of Water Treatment; Sedimentation

Silly Alligators Pee Constantly Sadly Doe

A

Large solids settle on the bottom of the tank and then are removed and used for fertilizer

32
Q

Step 6 of Water Treatment; Disinfection

Silly Alligators Pee Constantly Sadly Doe

A

Water is treated with chlorine and UV light to kill any remaining bacteria

33
Q

Where are the most micro plastics located

Why are microplastics dangerous

A

Center of Gyre

Gets stuck in their bodies, they feel full and starve
Gets stuck in their bodies and causes harm to their development

34
Q

Burning fossil fuels produces the gas carbon dioxide which creates carbonic acid and results

A

in death to coral reefs and death to marine organisms

35
Q

How does sea ice keep polar waters cold?

A

Sea ice reflects light

36
Q

Consequences of melting sea ice

A

Sea levels rising, climate change, disrupts global conveyer belt, harm to polar organisms

37
Q

Artificial Stabilization

A

Preventing naturally caused erosion

38
Q

Seawalls

A

Built parallel to beach to prevent erosion on beach front properties

Effects; Worsens on beach erosion

39
Q

Groin

A

Walls built perpendicular to beach to trap sand

Effects; Deprives nearby beaches of sand

40
Q

Beach Nourishment

A

Replenishing beach with sediment

Effects; Expensive, temporary, harms marine habitat
