10. Alum Coagulation:

Alum, or aluminum sulfate, can be used as a coagulant to clarify water. By adding alum to untreated water, suspended particles clump together and settle at the bottom, making it easier to remove impurities through subsequent filtration. This method is often employed in combination with other purification techniques.

Expanding the Horizons of Simple Water Purification Methods

UV Water Purifiers

UV water purifiers utilize ultraviolet light to deactivate and destroy the DNA of microorganisms present in water. While these devices are more commonly seen in advanced filtration systems, smaller, portable UV purifiers are available for personal use. They provide a quick and efficient way to ensure water safety without altering the taste or odor.

Moringa Seed Powder Clarification

Moringa seeds, known for their natural coagulant properties, can be used to clarify water. Crushed moringa seeds release proteins that bind with impurities, causing them to settle at the bottom. This natural method is particularly useful in areas where moringa trees are abundant.


Ozonation involves the use of ozone, a powerful oxidizing agent, to disinfect water. Ozone effectively eliminates bacteria, viruses, and organic contaminants. While ozone generators may be more sophisticated, the concept is simple – bubbled ozone oxidizes and neutralizes pollutants in water, leaving it safe for consumption.

Copper Sulfate Treatment

Copper sulfate is an affordable and accessible water treatment option. By adding small amounts of copper sulfate to water, algae and bacteria are effectively controlled. However, it’s crucial to use copper sulfate cautiously, as excessive levels can be harmful to aquatic life and humans.
