How to Make a Homemade Water Purification System?

Fresh and clean drinking water is essential for human survival, but unfortunately, access to safe drinking water is a scarcity in many parts of the world. In this article, we will guide you on how to make a homemade water purification system using readily available materials.

Why Do I Need a Homemade Water Purification System?

Before we dive into the process of making a homemade water purification system, let’s understand why having one is crucial. Untreated water can contain pathogens, heavy metals, chemicals, and other contaminants that can cause serious health issues such as:

• Water-borne diseases like cholera, typhoid, and dysentery
• Cancer and other severe health problems caused by contaminants
• Skin and lung infections from inhaling toxic particles

Type of Contaminants We Need to Remove

To make an effective homemade water purification system, we need to be aware of the types of contaminants we need to remove. These include:

Physical Contaminants: Sand, silt, sediment, and other particles larger than 0.001 millimeters

Bacterial Contaminants: E. coli, Campylobacter, Shigella, and Salmonella

Viral Contaminants: Viruses like Rotavirus and Norovirus

Chemical Contaminants: Heavy metals like Mercury, Lead, and arsenic, as well as pesticides and herbicides

Other Contaminants: Radon, arsenic, and other environmental pollutants

Basics of Homemade Water Purification System

A homemade water purification system typically consists of:

1. Pre-filtration: Removing coarse particles and sediment using techniques like sedimentation or activated carbon filtration

2. Primary Filtration: Removing smaller particles, bacteria, and viruses using techniques like ceramic filtration, UV light, or ultrafiltration

3. Secondary Filtration: Removing remaining contaminants like heavy metals, pesticides, and herbicides using techniques like reverse osmosis or activated alumina

4. Disinfection: Killing remaining microorganisms using techniques like disinfectants, UV light, or boiling

In this article, we’ll focus on a simple 4-stage homemade water purification system using readily available materials. This system will remove various contaminants, including physical and bacterial contaminants.

Materials Needed

To make the homemade water purification system, you’ll need the following materials:

• A large bucket or container: for sedimentation and chemical reactions
• Cheesecloth or an old t-shirt: as a pre-filter
• Activated carbon: 1-2 cups as a primary filter
• Ceramic tiles or coffee filters: for secondary filtration
• Reverse osmosis or activated alumina: 1-2 cups (optional) for secondary filtration
• Disinfectant: bleach (5-10 drops in 1 liter of water) or UV light or boiling
• Straws or tubes: to transfer water between stages
• Measuring cups: for measuring water and adjusting pH levels
• pH test strips (optional): to ensure water pH levels are balanced

Step 1: Pre-Filtration

1. Pour the polluted water into the large bucket or container.
2. Add the cheesecloth or old t-shirt into the bucket, making a pre-filter bag.
3. Allow the water to sit for about 30 minutes to settle, allowing the larger contaminants to settle at the bottom of the bucket.
4. Carefully pour off the top layer of settled water into a separate bucket, leaving the sediment at the bottom.

Step 2: Primary Filtration using Activated Carbon

1. Mix 1-2 cups of activated carbon with approximately 1 liter of treated water from Step 1.
2. Stir well and allow the mixture to sit for about 30 minutes to allow the activated carbon to absorb impurities and contaminants.
3. Squeeze the mixture through cheesecloth or a paper towel to remove the used activated carbon.
4. Collect the filtered water into a separate bucket.

Step 3: Secondary Filtration using Ceramic Tiles or Coffee Filters

1. Cut the ceramic tiles or coffee filters into the desired size for the filtration process.
2. Arrange the ceramic tiles or filters in a layer, staggering them to ensure maximum surface contact.
3. Pour the filtered water from Step 2 over the ceramic tiles or filters.
4. Allow the water to drizzle through the filters into a separate bucket.

Optional: If you wish to add an additional secondary filtration stage, you can use reverse osmosis or activated alumina filter. Follow the manufacturer’s instructions for installation and setup.

Step 4: Disinfection

1. Add 5-10 drops of bleach per 1 liter of treated water to the filtered water from Step 3, stirring well to ensure homogenization.
2. Allow the water to stand for 30 minutes, then pour off the upper layer into a separate container.
3. Alternatively, you can use UV light or boiling to disinfect the water.

Final Steps

1. Before consuming the purified water, it’s essential to double-check the pH levels.
2. Use pH test strips to ensure the pH levels are within the accepted range (6.0-8.5) for human consumption.
3. If necessary, make adjustments to the pH level using baking soda or a pH adjuster.
4. Store the purified water in a clean, protected container for later use or consumption.

Conclusion
Making a homemade water purification system is a simple process that requires minimal materials. By following these steps and using the right materials, you can remove various contaminants and create a safe source of drinking water. Whether you’re preparing for natural disasters, traveling, or simply wanting to ensure safe drinking water, this method can be a reliable backup system.
