Aquatic Facility Operator
What is NOT one of the AFO's primary responsibilities? - ANSTeaching Lessons
What should you do every day as a part of your AFO safety duty program? - ANSFacility
Inspection
How many gallons of water is in one cubic ft? - ANSapproximately 7.5
How do you calculate how many gallons are in a pool? - ANS1. calculate the volume
(LxW)xDavg
2. multiple by 7.5 gallons
Law of Dilution - ANSDuring a turnover less than half of the water molecules pass through the
filter
What kind of pools need a higher turnover? - ANSSpecial pools
When do gutters NOT work? - ANSwhen flooded
What do surge pits need? - ANSroom to contain surge flow
What do modulating float valves regulate? - ANSthe amount of water contributed by the bottom
outlet by slowly restricting the bottom drain valve as the water level in the surge pit rises
What are the two types of pumps? - ANSSelf-Priming and Flooded Suction Centrifugal
4 inches = - ANS400 gpm
What does eliminating dead spots mean? - ANSHeated and treated water is equally distributed
in the pool
Horizontal High Rate Sand Filter - ANSincreases surface area
When do you backwash? - ANSWhen the pressure differential indicates it is needed
When do you body feeding (DE) ? - ANSduring the filter cycle
What is oxidation? - ANSa chemical process that destroys organic compounds in the pool water
What is disinfection? - ANSthe chemical process that kills or deactivates pathogens
