The supplied diagram demonstrates how to produce clean water by using a simple water-filter assembly.
In general, it is obvious that there are 4 main steps in the process, beginning with pouring in dirty water and finishing with drinking clean water.
To begin with, a plastic barrel and a storage drum are placed next to each other. In addition, they are connected by a pipe from the bottom of the barrel to the drum. After lifting the plastic lid, unclean water is poured into the barrel and undergoes a filtering stage that consists of 3 layers of gravel, charcoal, sand arranged in turn from the bottom of the barrel. During this step, all the bacteria, particle and contaminant are eliminated from the water.
Turning to the next stage, the treated water drift along the pipe into the drum, where it is stored. Finally, when the tap in the drum is opened, clean water is flowing into a cup to drink.
