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 diagram below.
SAMPLE ANSWER
The given diagram shows the process of producing clean drinking water by a water filter. It can be seen that there are numerous steps in the process from the initial impure water to the final potable water.
In the first step, impure water is put into a metal (iron or steel) container with a wooden top. In the metal container there are three filtering layers, namely sand, charcoal and gravel, with sand at the top and gravel at the bottom. In the bottom part, the water, which is filtered through the three layers, is stored temporarily.
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. 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 part of the tank, through which the clean drinking water can be taken out for drinking.
