Answers & Comments
The best order to use stone, pebbles, gravel, and cotton balls to filter dirty water is as follows:
a. Cotton Balls: Place a layer of cotton balls at the bottom to trap large particles and debris.
b. Gravel: On top of the cotton balls, add a layer of gravel. Gravel helps in removing larger impurities and provides a stable base for the subsequent layers.
c. Pebbles: Place a layer of pebbles on top of the gravel. Pebbles further filter the water by trapping medium-sized particles.
d. Stone: Finally, add a layer of stones on top of the pebbles. Stones remove smaller particles and help in the physical filtration of the water.
2) Sand and Gravel Filtration:
Sand: Sand has a high surface area and can trap small particles suspended in water. As water passes through the sand, impurities are trapped in the gaps between the sand particles.
Gravel: Gravel provides a coarse filtration layer, removing larger particles. It also prevents the sand from clogging by creating channels for water flow.
3) yes, It is generally better to use crushed charcoal rather than large pieces. Crushed charcoal has a larger surface area, which enhances its ability to adsorb impurities and toxins from the water, making the filtration process more effective.
4) Charcoal, especially activated charcoal, is highly porous and has a large surface area. When water passes through charcoal, impurities, chemicals, and contaminants adhere to the surface of the charcoal due to a process called adsorption. Charcoal can effectively remove odors, chemicals, and some heavy metals, making the water cleaner and safer to drink.
5) Functions of Filtering Components:
a. Gravel: Provides a base for the filtration system, removes larger debris, and allows water to flow through.
b. Pebbles: Further filters water by trapping medium-sized particles and helps prevent clogging of the lower layers.
c. Cotton Ball: Acts as a p r e-filter, capturing large particles and debris before water passes through the gravel and pebble layers.
In a practical setup, these components work together to physically and chemically filter the water, providing a multi-layered approach to removing impurities.
