Some months ago we visited a water treatment plant.
This water treatment plant is located in a small village very close to
Guadalajara; the name of this village is Mohernando. We learnt many different
things about water and all the processes it undergoes to become drinking water.
Most of the water we use in Guadalajara comes from the River Sorbe. Although
this water is very good, it must be cleaned before we drink it, and this is
what they do at the water treatment plant. They explained us about the three
different processes water suffers in order to become drinking water, these
processes are: disinfection, decantation and filtering.
During disinfection process water is disinfected, this
is done with ozone and chlorine. Next, during decantation process water is
cleaned, in order to clean water they use pax and starch. Finally, clean water
is filtered. After these three processes water is totally clean and ready to be
drunk. This clean water is then carried through big pipes from the water
treatment plant to water tanks. From these water tanks water travels through
smaller pipes to many different places such as factories, schools, houses…
Besides, this water treatment plant is also in charge of the maintenance of the
clean water in our area.
To
finish, I have to say this was a very interesting visit in which we learnt a
lot about water and about the importance of water treatment plants. We really
enjoyed it.
