In this article I am providing the information on how to make water purifier-filter working model using waste bottles
Creating a simple water purifier using a plastic bottle, gravel, sand, and coal is a basic filtration system that can help remove larger impurities from water.
However, it’s important to note that this model is not sufficient for comprehensive water purification, and it won’t remove harmful bacteria or chemicals.
For practical water purification, advanced filtration methods and disinfection processes are necessary. Here’s a step-by-step guide to making the basic water purifier model:
Materials you will need:
- Plastic bottle (500 ml or 1-liter size)
- Gravel (small stones)
- Activated carbon (available in small pieces or crushed charcoal)
- Cotton or filter paper (optional, for additional filtration)
- Funnel (optional, for easier pouring)
- Dirty water (to test the filtration)
- Prepare the plastic bottle:
- Rinse the plastic bottle thoroughly to remove any residue or contaminants.
- Layer the filtration materials:
- Start by adding a layer of gravel at the bottom of the bottle. This layer will act as the first stage of filtration, removing larger particles and sediment.
- Next, add a layer of sand on top of the gravel. The sand will serve as the second stage of filtration, further removing smaller particles from the water.
- Lastly, add a layer of activated carbon on top of the sand. The activated carbon will help remove certain impurities and odors from the water.
- Optional: Add a cotton or filter paper layer:
- If you want to enhance the filtration, you can place a layer of cotton or filter paper above the activated carbon. This additional layer will help trap finer particles and improve water clarity.
- Assemble the water purifier:
- Make sure the layers are well-packed and firmly placed to prevent water from bypassing the filtration media.
- Test the water purifier:
- Pour dirty water into the top of the purifier and observe how the water passes through the layers of gravel, sand, and activated carbon. The water that comes out at the bottom should be cleaner and clearer than the water you poured in.
