The provided diagram illustrates how a simple water filter system turns dirty water into drinking water.
In general, the system consists of two main parts, the filter and the storage drum. Dirty water goes through several filter layers before becoming clean water, which is stored in the storage drum.
The system is a cylinder-shaped object with a plastic lid on top. Inside the filter, there are three layers, including gravel at the bottom, charcoal in the middle, and sand on top. These layers take up the bottom half of the filter part, while the top half holds dirty water that needs filtering. After being filtered, water goes through a pipe, which is located at the bottom of the filter, to the storage drum. People can take water using a faucet on the side of the storage drum.
Compared to more complex filtration systems, this method is simple and cost-effective, though it may be less efficient for heavily contaminated water due to its reliance on basic materials.
