Natural filtration methods
In order to effectively chlorinate turbid water,
it is useful to either let the water settle or filter
it through a cloth.
Settling and decanting the
water (often known as the three pot method)
is an effective way to reduce turbidity and to
reduce the demand for chlorine but requires
at least 2 containers.
Aluminium sulphate
and moringa seeds are
two naturally occurring flocculants. In many
countries
„alum‟ can be bought as a block of
white stone that is stirred in turbid water. This
causes the solids to clump together and then
they
will then settle out, allowing the cleaner
water to be decanted. However using too
much alum can affect
the taste of the water
and make it unpalatable.
