The diagram below illustrate how a simple water filter is constructed and how it functions to produce clean drinking water. Write a report for a university lecturer describing the diagram below.

The given diagram shows the process of producing clean drinking

water

with a

water

filter.

Overall

, it can be seen that there are numerous steps in the process from the initial impure

water

to the final portable

water

.

To begin

with, let us shed light on the first step, impure

water

is put into a metal container with a wooden lid. In the metal

container

Add a comma

container,

show examples

there are three filtering layers, namely sand, charcoal and gravel, with sand at the top and gravel at the

bottom

.

Additionally

, in the

bottom

part

, the

water

, which is filtered through the three layers, is stored temporarily.

Further

, an angled metal pipe is there which has the lower opening in the

bottom

part

of the

water

filter

tank

. The upper

part

of the pipe comes out from the upper

part

and is linked to another closed metal

tank

.

Finally

, the filtered

water

from the first

tank

is brought into the second

tank

, which is at a lower level than the first

tank

. There is a tap attached to the

bottom

area of the

tank

, through which the clean drinking

water

can be taken out for drinking.
