Produce drinking water from raw wastewater The main responsibility of a wastewater treatment plant operator
Chemical feed rates remain constant A treatment plant operator must understand process control because:
The best way for an operator to improve job Delegate testing to others
performance is to:
Which of the following is an example of preventive Replacing parts during routine inspections
maintenance
Which of the following is not a responsibility of a Maintaining operating records
treatment operator?
The total oxygen in the water Biochemical Oxygen Demand (BOD) measures
The average BOD of domestic wastewater is 200 mg/L
approximately
The term "influent" refers to Wastewater entering the plant

A low pH in wastewater indicates: Acidic conditions
The term "TSS" stands for: Total Suspended Solids
Which type of solids can be removed by primary Suspended solids
sedimentation?
Temperature affects wastewater treatment by Microbial activity and reaction rates
influencing:
The most common source of infiltration into sanitary Leaking joints and cracked pipes
sewers is:
The main purpose of preliminary treatment is to: Remove large debris and grit to protect equipment
Bar screens are installed to Remove large solids and rags from influent flow
Grit chambers are designed to remove: Heavy inorganic particles such as sand and gravel

The velocity of flow through a grit chamber should be 1.0 ft/sec
approximately:
A comminutor is used to Grind and shred solids in the influent flow
Parshall flumes are used primarily for: Flow measurement
If grit accumulation increases rapidly in the chamber, it Improper flow velocity or channel design
usually indicates:
The primary purpose of primary clarifiers is to: Remove settleable solids and reduce organic load
The normal detention time for primary clarifiers is 1.5-2.5 hours
approximately:
The weirs on a primary clarifier should be Level to ensure uniform flow distribution
The typical removal efficiency for suspended solids in 40-60%
primary treatment is
