Second Stage: Ozone Disinfection

Ozone is the primary disinfectant used in the regional surface water treatment plant.  Used throughout the United States, it is the most powerful disinfectant in water treatment today.  Ozone kills microorganisms that may be left in the water, including bacteria, viruses and protozoa.

Third Stage: Biologically Active Filtration

Water moves from the ozone tank to the biologically active filtration area where “good bacteria” aid in removing remaining organic molecules.  After that, layers of sand and granular activated carbon filter out any remaining particles.  The water is then disinfected again, using a two-process process of chlorine and chloramines, before it is blended with other treated supplies and distributed to Tampa Bay Water’s member governments.
