The diagram depicts the construction and operation of a basic water filter designed to produce clean drinking water.
This system consists of a plastic barrel with multiple filtering layers and a storage drum, which work together to purify water and create pure water.
At the beginning of the process, contaminated water is introduced into the system through an opening in the plastic lid before undergoing purification with three filtering materials including sand, charcoal, and gravel. This step would help to purify the water, with each component significantly contributing to the removal of impurities.
Upon completion of the filtration process, the cleansed water is collected at the bottom of the plastic barrel before being drawn through a pipe into an adjacent container, ready for domestic or industrial use.
