Sewage Treatment
List the potable water treatment in the correct order. Use filtration, sedimentation, disinfection, and coagulation.
Coagulation, Sedimentation, Filtration, Disinfection
Coral reefs are rocky mounds and/or ridges formed in the sea by marine organisms through the accumulation and deposition of (BLANK)
limestone (calcium carbonate).
How do Crown of Thorns Starfish eat?
Adult opportunistic carnivore: stony corals by everting stomach onto coral substratum and digesting polyps.
What type of estuaries are characterized by a deep elongated basin that is U-shaped and a ledge or barrier that separates the basin from the sea?
Fjord
What does NTU stand for?
Nephelometric Turbidity Units
What is the main difference between potable water and wastewater treatment?
A) Sedimentation B) Filtration C) Sludge D) Chemical Cleansing
C) Sludge
These small marine animals, (individual organisms are called (BLANK), produce a hard skeleton made of calcium carbonate, which they extract from the seawater and combine with CO2 for limestone.
Polyps
How much do groupers weigh?
100kg
Gravitational pull of sun & moon & rotation of Earth, moon, & sun. Moon’s influence - gravity strongest on side of earth closest - pulls water in ocean toward it.
What are the units for measuring Fecal Coliform in water?
Number of bacterial colonies/ 100 mL Water
In tertiary treatment, the fluid from secondary treatment is treated to remove (BLANK) and (BLANK) products
Nitrates and Phosphates
Name the difference between Hermatypic and Ahermatypic Corals
Hermatypic Corals - Corals that form large colonies called reefs and have a symbiotic relationship with the dinoflagellate Zooxanthell.
Ahermatypic Corals - Corals that are solitary or form small colonies- they often lack symbiotic relationships with Zooxanthellae and don't help build reefs.
What are the two groups of hard coral?
Colonial and Solitary
Of the (BLANK) of water that is fresh water, (BLANK) is frozen in ice caps and only (BLANK) is usable by organisms as liquid water or water vapor found in lakes, rivers, streams, ponds, in the ground water, and as vapor in the atmosphere.
3%, 2%, 1%
Higher temperatures cause (increase/decrease) in metabolic rate of organisms and BOD (biochemical oxygen demand)
Increase
Place the steps of drinking water treatment in order (fluoridation/chlorination, filtration, flocculation/coagulation)
flocculation/coagulation, filtration, fluorination/chlorination
Final stage of reefs are extinct reefs as a (BLANK) (an underwater mountain) or (BLANK) (underwater mountain or seamount with a flat top)
Seamount, guyot
What is Aposometism, and what animal uses it?
Flamingo Tongue Snail, Bright colors warn predators of poison
What word describes the stickiness (cohesion) of water molecules allowing water to go up a small tube?
Capillary Action
If the pH of a body of water is 6, what is the pOH, and what is the concentration of OH- ions, and what is the concentration of H+ ions?
pOH- 8
Concentration OH- = 10^-8 M
Concentration H+ = 10^-6 M
In which step of Wastewater treatment is a biological treatment in which majority of nutrients are removed?
Secondary Treatment
Coral are actually a special group of (BLANK)
cnidarians
Name a purpose for Long-Spined Black Sea Urchin Eggs
Eggs used in embryonic research
Which type of estuary has salt water mixed upward and fresh water is mixed downward. The lower layers of water typically remain saltier than the upper layers
Partially mixed, or Slightly Stratified
What does TDS stand for, and name one way to measure it in water?
Gravimetric analysis and conductivity, the former being the more accurate method. The gravimetric method involves evaporating the liquid and measuring the mass of solids left behind and should be used if inorganic salts comprise most of TDS. Measuring the electrical conductivity of the water can also help determine TDS
