The Ceramic Filtration System – For a mere $20 US dollars an easy to use filtration system can be constructed and installed using locally available materials. This system is especially valuable in areas where electricity is not available or where minimal understanding of germs and water born illness is prevalent.
How does it work?
- A specially constructed clay/ceramic pot is placed inside the top of a large water storage container.
- Contaminated water is poured into the ceramic pot.
- As the water seeps through the porous pot, nearly all of the impurities are removed.
- Pure drinkable water is collected in the large water container.
- Drink up!
Pros: Very inexpensive. Very easy to use. Removes all germs and bacteria from water. Works with both rain water and surface water. Purifies 2 liters per hour. (as of this publication)
Cons: Cannot remove arsenic from water. As a result, this is not a good device for arsenic contaminated well water. (Its best used in Cambodia for rain and surface water.) Not time efficient for purifying large quantities of water.
