The Breese
Water Treatment Plant is a conventional surface water
treatment plant. Its raw water source is Shoal Creek with a
thirty day supply reservoir adjacent to it. We treat water
by coagulation and sedimentation.
The raw water is pumped from either the creek or the
reservoir where potassium permanganate is added. This
chemical is a strong oxidizer. We use it to oxidize
manganese into an insoluble form so it can be removed by
settling out in the basins or by filtering it out. The
water then enters the plant and aluminum sulfate (alum) and
a cationic polyelectrolyte is added to the water and mixed.
The chemicals react with the dirt and slit in the water to
form floc. These chemicals have a positive charge and the
dirt has a negative charge so they attract each other to
form floc.
The water continues to
mix and an anionic polyelectrolyte in added. This polymer
is used to kind of glue the floc together to form bigger and
heavier floc. This will help in the settling process.
Calcium hydroxide (lime) is then add to the water for PH
control.
The water continues
through the mixer and in the last one activated carbon is
added for taste and odor control. It then enters the
settling basins, the floc settles out and enters troughs
that bring it through the filters. Chlorine is added at the
trough for disaffection purposes. After the water is
filtered it is collected in the clear well where fluoride,
ammonia and more chlorine is added.
The plant supplies the
City of Breese, St. Rose and the North Water District. It
also supplies the village of Germantown. It averages
555,000 gallons per day. The maximum output capacity of the
plant is 1,200,000 gallons per day. The maximum demand in
one day is 900,000 gallons. The plant serves a population
of about 4100 people in the City of Breese alone.
