When it
comes to treating water for drinking, two terms come to mind:
purification and filtration. While they’re often used
interchangeably, filtration and purification differ in many
fundamental ways.
Of the
two, purification is more misunderstood. A lot of people believe that
water is “pure” if it doesn’t have anything mixed with it. But
the gist of the term is in its root word “purify,” which by
definition means removing what is unwanted and not necessarily all
that isn’t H2O. The only components targeted by iodine or
chlorine water purification are harmful contaminants like viruses,
chemicals, and their ilk. Of the two water treatment methods,
purification is considered less effective as it can’t always remove
every impurity there is.
