Introduction

This tutorial outlines the process of creating a simple water filtration system, which is essential for ensuring access to clean drinking water. Clean water is a critical factor in preventing health issues like stunting. This guide will provide you with step-by-step instructions on how to build an effective water filter using readily available materials.

Step 1: Gather Your Materials

Before you begin constructing your water filter, collect the following materials:

• Plastic bottle (cut in half)
• Sand
• Gravel
• Activated charcoal
• Cotton or a coffee filter
• Clean container for filtered water

Practical Tips

• Ensure all materials are clean to avoid contaminating the water.
• Choose a transparent plastic bottle for better visibility of the filtration process.

Step 2: Prepare the Bottle

1. Take the plastic bottle and invert the top half into the bottom half.
2. If you have a cap for the bottle, make sure to poke a hole in it to allow water to flow through.

Common Pitfalls to Avoid

• Ensure the bottle is stable when inverted to prevent spills.
• Make sure the hole is not too large, as this may allow unfiltered water to escape.

Step 3: Layer Your Filtration Materials

1. Start with a layer of cotton or a coffee filter at the bottom of the inverted bottle. This will act as the first barrier for larger particles.
2. Add a layer of activated charcoal on top of the cotton. This will help remove impurities and odors from the water.
3. Next, put a layer of sand. Sand helps in filtering out smaller particles.
4. Finally, add a layer of gravel at the top. This layer aids in preventing the sand from being disturbed when water is poured in.

Practical Advice

• The order of layers is crucial for effective filtration. Always start with the finest material at the bottom and coarser materials at the top.

Step 4: Filter the Water

1. Pour the water you wish to filter into the gravel layer slowly.
2. Allow the water to pass through all layers and collect it in the clean container below.

Tips for Effectiveness

• Pour the water gently to avoid disturbing the layers.
• If the water is very dirty, you might need to filter it multiple times for better clarity.

Conclusion

You have successfully created a simple water filtration system. This DIY filter can help provide cleaner water, contributing to health and well-being. For ongoing improvement, consider experimenting with different materials or configurations to enhance filtration. Remember to regularly clean and maintain your filter for optimal performance.
