The diagram illustrates a straightforward mechanism for converting contaminated water into clean drinking water using a basic water filtration assembly.
The system consists of two storage drums, one for filtering and one for storing the purified water. The process begins by pouring unclean water into an upper plastic drum, where it undergoes filtration through three distinct layers: gravel, charcoal, and sand. Finally, the purified water is stored in a lower drum equipped with a tap for convenient access.
Initially, the lid of the upper drum is removed, allowing the unpurified water to be poured in. As the water flows down, it percolates through the filtration layers. The sand acts as a fine filter, removing small particles, while the charcoal eliminates impurities and contaminants, and the gravel provides additional support for the filtration process. Once filtered, the clean water is directed through a pipe system to the lower storage drum.
In the final stage, the clean water is securely contained within the lower drum, which is sealed to prevent contamination. A tap at the bottom allows users to draw purified drinking water easily. Overall, this process involves a series of straightforward steps, from initial filtration to final storage, culminating in the availability of safe, clean drinking water.
