The diagram below illustrates 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 information shown below. Summarise the information by selecting and reporting the main features and make comparisons where relevant.

The diagram provides information concerning the steps and methods to make

water

clean drinking

water

.

Overall

, it can be clearly seen that there are 3 stages of production. Commencing with pouring

water

into a plastic barrel and culminating in releasing

water

by the tap for consumption.

To begin

with, there are several steps to produce the clear

water

. The first and most essential step is that the plastic barrel with 3 preferred elements inside which are sand, charcoal, and gravel needs to be prepared.

Then

, add the raw

water

to

this

prepared keg, and do not forget to protect it from any dusk by using a plastic lid covering. In the

last

process before exporting, after the

water

passes through the sand, charcoal, and gravel,

this

pure liquid is going to be collected in the storage drum.

Finally

, the manufacturer will transport these casks to a residential area or supermarket.
