Need Clean Drinking Water? Make Your Own DIY Clay Filter
It’s a sad fact that most of the water in the world needs filtering before it can be safely drunk. It’s the result of many years of industrialization and the resulting pollution in the air, soil, and water. However, most water filters are a fairly expensive and technology-dependent solution to the problem, and it’s not a feasible option for many less privileged people around the world who suffer from polluted water sources. But this clay water filter might just be the inexpensive, practical solution that we need!
I really want to try this. This DIY clay filter requires very few and common ingredients, and can be made very quickly and easily. From Planet Green comes the instructions:
The filter is created with clay, organic materials (coffee grinds or rice), water and manure. The straw and rice are mixed in with the clay and water and then fired over some burning manure. The organic materials are burned away during the firing process and create small passages in the filter that allow water, but not pathogens, to pass. This filter effectively removes 96.4-99.8% of E. Coli in water. One of these filters can great a liter of drinkable water in only two hours. You can make your own filter by following these steps:
1. crushed, dry clay
2. organic material(tea leaves, cofffee grounds, or rice hulls)
4. Cow manure
1. Mix in enough water to make a stiff biscuit-like mixture
2. Form a cylindrical pot that has one closed end
3. Dry the pot in the sun
4. Surround the pot with straw and place it in a mound of cow manure
5. Light the straw and then top up the burning manure as required.
6. Filter will be completed in less than an hour.
Pretty neat, huh? Clay can be found literally everywhere, which makes this filter solution an extremely appealing answer to the global water purification problem. Try it out!
