What Does it Take to Treat the Water?
The process consists of coagulation, flocculation, sedimentation, filtration, fluoridation, and disinfection. The influent metering/control vault measures and controls the flow of raw (untreated) water into the treatment process. The majority of the treatment process components are automatically controlled via computers based on flow metering at this structure. The rapid mix basins are where chemicals are added and mixed with the water. These chemicals are needed to remove the extremely small suspended solids from the water. The flocculation basins provide an environment where the chemicals and the suspended solids interact to accumulate into larger masses called "floc." In the sedimentation basins, the majority of the "floc" settles out of the water, and the supernatant is drawn off and conveyed via underground piping to the facility’s building for filtration.
