FLORIDA WASTEWATER CORE EXAM MANUAL 2025/2026
QUESTIONS AND ANSWERS RATED A+
✔✔Digestion - ✔✔The breaking down of sludge and other waste biologically by
microorganisms. Results in byproducts such as methane gas, carbon dioxide, sludge
solids and water. Aerobic digestion requires oxygen, anaerobic digestion the absence of
oxygen.
✔✔Denitrification - ✔✔Biologically removing nitrate converting it to nitrogen gas.
✔✔Disinfection - ✔✔The use of chemicals to kill any disease causing organisms in the
polished wastewater. UV light can also be used.
✔✔Dissolved Oxygen (DO) - ✔✔The amount of oxygen dissolved in the water.
Measured in milligrams per liter.
✔✔Ecological Engineering - ✔✔Systems designs that are considered to be
"sustainable", that is with the aim of having little to no impact on earth's ecology.
✔✔Effluent - ✔✔The final output flow of a wastewater treatment plant.
✔✔Extended Aeration - ✔✔An aeration system that adds aerobic sludge digestion to
the activated sludge process.
✔✔Facultative Ponds - ✔✔Wastewater ponds with some form of aeration for oxygen
replenishment. Can also use algae and other plants for oxygen replenishment.
✔✔Floc - ✔✔Particulate and or bacterial clumps forming wooly looking clusters in
wastewater. In biological processes such as extended aeration or activated sludge and
others the floc contains aerobic or anaerobic microorganisms.
✔✔Flocculation - ✔✔The process whereby a chemical or other substances is added to
wastewater to trap or attract the particulate suspended solids into clusters or clumps of
floc or flocculent, wooly looking masses.
✔✔Flocculating agent - ✔✔The flocculant or chemical used to cause flocculation
✔✔Free Water Surface Wetland (FWS) - ✔✔A constructed wetland or other shallow
wastewater treatment pond where the shallow water is exposed directly to the air.
✔✔Grease - ✔✔Fats, soaps, oils, waxes and etc. in wastewater.
