Title: Water Purification Using Moringa Seeds and Cactus Mucilage
Introduction
Water contamination is a critical challenge, particularly in regions with limited access to clean water. Natural coagulants, such as Moringa seeds and cactus mucilage, have demonstrated potential in improving water quality. This project explores the synergistic use of Moringa seeds and cactus mucilage to remove turbidity and contaminants from water, offering a sustainable, cost-effective solution for water purification.
Statement of the Problem
Millions of people worldwide lack access to clean drinking water, leading to health hazards such as waterborne diseases. Conventional water treatment methods are often expensive, inaccessible, or environmentally damaging. This project aims to address these challenges by utilizing locally available, natural materials (Moringa seeds and cactus mucilage) to purify water effectively.
Objective
To investigate the effectiveness of Moringa seeds and cactus mucilage in purifying turbid water by reducing turbidity, removing impurities, and improving water quality parameters.
Apparatus
- Dried Moringa seeds
- Fresh cactus pads (for mucilage)
- Beakers (500 mL and 1 L)
- Measuring cylinder
- Stirring rod
- Cheesecloth or fine mesh
- Turbidity meter (if available)
- Funnel
- Filter paper
- Contaminated water samples (e.g., muddy water)
Procedure
- Preparation of Moringa Seed Powder
- Dry the Moringa seeds and grind them into a fine powder.
- Store the powder in an airtight container for use.
- Extraction of Cactus Mucilage
- Peel the cactus pads to remove the outer skin.
- Blend the inner gel with a small amount of water to extract mucilage.
- Filter the mucilage using cheesecloth or fine mesh.
- Water Treatment Process
- Pour 500 mL of turbid water into a beaker.
- Add 0.5 g of Moringa seed powder to the water.
- Stir vigorously for 5 minutes to ensure proper mixing.
- Let the mixture settle for 30 minutes.
- Add 10 mL of cactus mucilage to the same water sample and stir gently for 2 minutes.
- Allow the mixture to settle for another 30 minutes.
- Filtration
- Filter the treated water using filter paper in a funnel.
- Collect the purified water in a clean beaker for observation and testing.
Observation
- Turbidity reduction was observed after the addition of Moringa seed powder and cactus mucilage.
- Fine particles settled at the bottom of the beaker during the settling periods.
- The filtered water appeared clearer compared to untreated water.
Data
| Parameter | Before Treatment | After Treatment |
|---|---|---|
| Turbidity (NTU) | 200 | 20 |
| pH | 6.5 | 7.0 |
| Visible Clarity | Muddy | Clear |
| Sediment Volume (mL) | 0 | 5 |
Conclusion
The combination of Moringa seed powder and cactus mucilage effectively reduced turbidity and improved water quality. This method provides a sustainable and affordable solution for water purification, particularly in resource-constrained settings. Further research could explore scaling the process for larger water volumes.
