1. First action for a poly- Apply an absorbent to dispel such as sand or kitty litter and then sweep
mer spill? up the materials
2. Total discharge head in- Discharge pressure head + static discharge head + velocity head +
cludes? friction head
3. Where is the best loca- A location that represents the entire waste stream or basin
tion to collect a sample?
4. Preservation and hold- 48 hours at<=6 degrees centigrade
ing times for BOD sam-
ples
5. Define BOD The rate at which organisms use the oxygen in water or wastewater while
stabilizing decomposable organic matter under aerobic conditions. And
decomposition, organic matter serves as food for the bacteria and ener-
gy results from its oxidation. VOD measurements are used as a measure
of the organic strength of wastes and water
6. Purpose of a desiccator To allow residual samples to cool prior to weighing
7. What will happen if the Too much organic material will be deposited
flow to the grit chamber
is too low?
8. How does an operator Wasting in return activated sludge
control the suspended
solids in an activated
sludge basin?
9. Chlorine combines with Chloramines
ammonia to form what?
10. Flow, detention time, wasting and return rates

What can the operator
control with the activat-
ed sludge process?
11. What is the best way to Addition of chlorine to the return sludge
control filamentous bac-
teria?
12. A 5.2 acre lagoon with 470,577 gallons per day
an influence of 47,000
gallons per day is
dropped 3 inches a day
from a depth of 5 feet
to a depth of 2 feet.
How many gallons are
discharged each day?
13. Define endogenous res- A situation where living organisms oxidize some of their own cell material
piration instead of new organic matter they absorb or absorbed from their
environment
14. What should the veloc- At least 2.0 FPS
ity of the sewage in a
gravity sewer line be
coming into the waste-
water treatment plant?
15. What does hydrogen Cause corrosion
sulfide do in the collec-
tion system?
16. What must be on the Signature of person who locked out the switch and who is the only
warning tag attached to person authorized to remove the tag
