The diagram provides information about the construction stage of a simple water filter and how it works to manufacture clean drinking water. Overall, the process begins with the added water into the filter and finishes the storage drum container.
In the first stage, the plastic lid that is located at the top of the filter is removed by a human, and then water is added to the filter container. The filter container has three types of goods such as sand, charcoal, and gravel. The pink gravel is placed at the bottom of the machine, the brown charcoal is located above the gravel, and the yellow sand is placed below the water in the plastic barrel.
In the following stage, the added water is mixed with the products to purify water. The mixed goods are transferred to a storage drum with the help of a tube, and then the cleaned water is flowed into the cup, and ready to drink.
