The diagram 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 given.
The process of using a water filter to produce clean drinking water is depicted in the provided diagram. From the original impure water to the finished potable water, it is evident that there are several steps involved in the process.
The first step involves filling a wooden-topped metal (steel or iron) container with impure water. Three filtering layers—sand, charcoal, and gravel—are arranged in the metal container, with gravel at the bottom and sand at the top. The water that has passed through the three layers of filtering is temporarily held in the bottom section.
The bottom portion of the water filter tank has an angled metal pipe with a lower opening. A closed metal tank is connected to the upper section of the pipe that emerges from the upper section. In the second tank, which is situated below the first tank, the filtered water from the first tank is transferred.
It is possible to extract clean drinking water for consumption through a tap that is fixed to the bottom of the tank.
