The diagram illustrates a simple water-filter system used to convert dirty water into clean drinking water.
Overall, the system uses a plastic barrel with several filter layers and a storage drum to clean the water. The process involves gravity and natural materials like gravel, charcoal, and sand to purify the water.
To strart with, dirty water is poured through a plastic lid into the top of the plastic barrel. Inside the barrel, there are three main filtering layers. I addition, the water first passes through a layer of sand, which removes larger particles. Then, it flows through a charcoal layer that helps eliminate harmful chemicals and bad smells. The final layer is gravel, which filters out smaller impurities.
After the water moves through all the filtering layers, it travels through a pipe into the storage drum placed next to the barrel. This drum holds the clean, filtered water. A tap is attached to the bottom of the drum, allowing people to collect safe drinking water easily.
In conclusion, this simple and low-cost system is effective for producing clean water using natural materials.
