The diagram below illustrates how a simple water filter is constructed and how it functions to produce clean drinking water.

The diagram provides information about the construction of a simple

water

filter

and its mechanism of it to generate clean

water

. Impure

water

consists of stones and dust and

this

can be cleaned by a mechanical straightforward sieve. The

water

filter

is made up of layers of materials

such

as gravel on the lowermost

layer

and the middle

layer

is made up of charcoal and the upper

layer

contains sand.

Along with

this

, there is an opening that connects it to a drinking

water

storage

tank

.

First,

the impure

water

is poured into the container that has the

filter

system, and

then

it gets strained as it passes through the layers of sand and next into the charcoal

layer

later the specks of dust are removed in the lower

layer

from where a way is made as an outlet from the

filter

tank

to drinking

water

tank

.

Moreover

, filtered

water

is transferred to a drinking storage

tank

which has a tap for consumption.
