Instructions To Build a Nano-Tech Enhanced Water Purifier

1. Cut the Bottle: Use scissors to cut the plastic bottle in half horizontally. The bottom half will serve as the filter container, while the top half can be inverted to act as a funnel.
2. Remove the Cap: Take off the cap from the top half of the bottle.

Step 2: Create the Filtration Layers

1. Insert a Filter: Place a cotton ball or a coffee filter at the neck of the top half of the bottle to prevent the filtration materials from falling out.
2. Add Sand: Pour about an inch of clean sand into the top half, pressing it down lightly.
3. Add Activated Carbon: Next, add a layer of activated carbon (approximately 2-3 inches) on top of the sand. This layer is crucial as it will adsorb various contaminants, including chlorine, volatile organic compounds, and bad odors.
4. Add More Sand: Pour another layer of sand on top of the activated carbon. This layer helps filter out larger particles.
5. Add Silver Nanoparticles: Finally, sprinkle a layer of silver nanoparticles over the sand. Silver nanoparticles provide antibacterial properties, ensuring that any remaining bacteria in the water are neutralized.

Step 3: Assemble the Purifier

1. Combine Both Halves: Invert the top half of the bottle (the funnel) into the bottom half. Ensure it fits snugly.
2. Secure the Structure: Use tape if necessary to secure the two halves together and prevent leaks.

Step 4: Purify the Water

1. Collect Contaminated Water: Gather the water you want to purify in a separate container.
2. Pour the Water: Slowly pour the contaminated water into the funnel. Allow it to filter through the layers.
3. Collect Purified Water: The purified water will collect in the bottom half of the bottle. You can use this water for non-potable purposes, such as watering plants or cleaning.

Scientific Explanation

This DIY water purifier utilizes the principles of filtration and adsorption. Activated carbon works by attracting and binding various contaminants, effectively removing them from the water. The addition of sand acts as a pre-filter, capturing larger particles before they reach the activated carbon layer. The silver nanoparticles contribute to the purification process by providing antimicrobial properties, killing bacteria and viruses that may be present in the water.

The overall efficiency of this purification system can vary based on factors such as the initial water quality and the quantity of materials used. For more information on water purification methods and the science behind them, visit World Health Organization.

Advanced Filtration Techniques

If you want to enhance your nano-tech water purifier further, consider integrating the following advanced filtration techniques:

1. Use of Biochar

Biochar, a form of charcoal produced from organic material, can improve filtration quality. It enhances adsorption and can remove various pollutants from water. For more information on biochar, visit Biochar Journal.

Modification Steps:

• Replace or add a layer of biochar between the sand and activated carbon in your purifier.
• This will provide additional filtration properties and improve the removal of heavy metals and organic pollutants.

2. UV Light Treatment

Integrating UV light can effectively eliminate pathogens in the water. UV light disrupts the DNA of bacteria and viruses, rendering them harmless.

Modification Steps:

• After filtration, expose the collected water to a UV light source for a few minutes.
• Consider using a solar-powered UV light for an eco-friendly option.
