    Getting Started:

    • Materials Needed: Clear plastic bottles or glass jars, sunlight, and a little patience.

    The Process:

    • Preparation: Fill the bottles or jars with water. Pre-filter the water using a cloth or coffee filter if it is cloudy.
    • Disinfection: Place the water-filled containers in direct sunlight for 6-8 hours on a sunny day or 24-48 hours if overcast.
    • The Science: UV rays from the sun kill pathogens in the water, making it safer to drink. The process also improves the taste.

    DIY Filtration Method 4: Biosand Filter

    Getting Started:

    • Materials Needed: A concrete or plastic container, gravel, sand, and a diffuser plate.

    Building Your Filter:

    • Layering: Similar to the charcoal and sand filter, start with a layer of gravel at the bottom, then add sand. The sand should be fine and clean.
    • Bio Layer: Over time, a biological layer will form on top of the sand, which is crucial for the filtration process, breaking down pathogens and organic materials.
    • Operation: Pour water into the top, and it filters through to the bottom, where it can be collected.
    • Maintenance: Regularly remove and clean the diffuser plate, and occasionally stir the top layer of sand to maintain efficiency.

    Enhancing Filtration with Natural Coagulants

    What the heck is a Natural Coagulant?

    Nature’s Helping Hand:

    • Introduction to Natural Coagulants: Moringa seeds, an incredible gift from nature, have been used for centuries to purify water. These seeds act as natural coagulants, clumping impurities together to be easily removed.
    • Application: To use moringa seeds, shell, crush, and add them to a jug of water. Stir vigorously for about 5 minutes, then let the mixture sit. The seeds attract dirt and microbes, settling them at the bottom.
    • Effectiveness: Moringa seeds improve water clarity and have antimicrobial properties, making them a fantastic pre-treatment before filtration.

    Boiling: The Simplest Disinfection Method

    The old tried and true method.

    Turn Up the Heat:

    • Proper Techniques: Boiling water is straightforward but requires attention to detail. Bring water to a rolling boil for at least one minute (or three minutes at higher altitudes) to ensure all harmful organisms are killed.
    • When to Use: Boiling is most effective when used after physical filtration, especially if the water source is suspected of being contaminated with pathogens.

    Chemical Disinfection at Home

    So what’s under that kitchen sink of yours?

    A Dash of Chemistry:

    • Using Household Bleach: Household bleach (unscented chlorine bleach) can be a powerful disinfectant. For every gallon of water, use about four drops of bleach. Stir and let it stand for 30 minutes. The water should have a slight chlorine odor; if not, repeat the process and let it stand for another 15 minutes.
    • Precautions: Always ensure the bleach is not expired and is suitable for disinfection. Never mix bleach with other chemicals, as it can create dangerous reactions.
