The given diagram illustrates the configuration and the operational mechanism of a simple water filter.
Overall, the structure consists of two major components: a purification tank and a clean water storage tank, both of which are connected via a hose or a pipe. It is clear that the clean drinking water producing process commences with water cleaning and terminating with clean water being stored and ready for use.
Initially, impure water is poured into the filtration tank, whose bottom is layered with gravels, charcoal, and sand. These three layers reach up to half the height of the tank. Water then slowly permeates the filtering layers and gradually loses its sediments and other impurities before reaching the bottom of the tank. Besides, a linking hose (or pipe) located here is ready to direct clean water into another reservoir.
In the next stage of the process, thanks to the hose (or pipe), purified water is led into the drinking water storage tank from its top. Moreover, this tank also has a faucet attached to its bottom on the outside to eventually dispense water for multiple uses.
