Florida Wastewater Certification Exam Review 2026 |
Verified Q&A | Graded A+
1. Describe how the use of hypochlorinators can impact the overall safety of
treated wastewater.
Hypochlorinators improve the efficiency of wastewater treatment
without any risks.
Hypochlorinators can lead to the formation of harmful byproducts,
which may pose health risks.
Hypochlorinators are only used for odor control, not disinfection.
Hypochlorinators have no impact on the safety of treated wastewater.
2. Describe the role of ciliates in the context of good settling sludge in
wastewater treatment.
Ciliates are harmful to the treatment process and should be
eliminated.
Ciliates help in the breakdown of organic matter and indicate a
healthy microbial community in settling sludge.
Ciliates only contribute to the formation of scum on the surface.
Ciliates are not relevant to the quality of settling sludge.
3. Sodium Hypochlorite when added to the wastewater will
not effect the pH.
not react with hydroxide.
increase the pH.
Decrease the pH.
, not react with reducing agents in the wastewater.
4. What is the primary role of bacteria in the stabilization tank during the
contact stabilization process?
Chemical disinfection
Nutrient absorption
Filtration of solids
Decomposition of organic matter
5. What specific incidents must operators report to the permittee and the
department within 24 hours according to FDEP chapter 62-602?
Any unauthorized discharge or violation of permit conditions
Routine maintenance schedules
Staff training updates
Monthly sampling results
6. If the screenings dumpster is full and measures 6ft tall, 10ft long, and 8ft wide,
how many cubic yards of screenings must be disposed of in a 30-day month?
100 cubic yards
80 cubic yards
60 cubic yards
120 cubic yards
7. Reduced capacity with vibration and noise at the centrifugal pump suction
due to vapor pockets in the fluid being pumped is caused by _.
Incorrect fluid viscosity
, Cavitation
Aeration of the oil
Steam knock
8. Describe the role of anaerobic digestion in the overall wastewater treatment
process.
Anaerobic digestion is a method for filtering out pathogens from
wastewater.
Anaerobic digestion is primarily used for removing heavy metals from
wastewater.
Anaerobic digestion involves the addition of oxygen to enhance
microbial activity.
Anaerobic digestion helps reduce organic waste and produces
biogas, which can be used for energy.
9. Tasks performed by a collection system operator include:
Cleaning on-site industrial sewers
Making water connections
Maintaining collection system equipment
Cleaning local treatment plants
10. Describe why high toxicity levels can negatively impact microorganisms in
wastewater treatment processes.
High toxicity levels only affect the physical properties of wastewater.
High toxicity levels have no effect on microorganisms.
High toxicity levels can kill or inhibit the growth of microorganisms
essential for breaking down waste.
, High toxicity levels enhance the growth of microorganisms.
11. Which of the following tests can be run in the field by a certified operator or
trainee under direct supervision of the certified operator?
pH and CBOD
CBOD and TSS
Nitrate and temperature
total chlorine residual and pH
12. What is the primary material used in trickling filters for wastewater
treatment?
Sand
Clay
Plastic
Rock
13. If a wastewater treatment plant is experiencing low chlorine residual due to
ice on the feed lines, what operational change could be implemented to
mitigate this issue?
Switch to a different disinfectant method.
Increase the flow rate of chlorine to compensate for the loss.
Reduce the temperature of the treatment plant.
Insulate the chlorine regulator and feed lines to prevent ice
formation.
