How To Make A Bio-Sand Filter To Filter Collected Rainwater
Most people who collect rainwater, do so for watering their garden and crops. The thing is, rainwater collected from the roof of your home etc is perfectly drinkable if it is first filtered, to take out any toxins and bacteria etc. You don’t need a high-tech expensive industrial water filter system to do this; you can easily make something known as a bio-sand filter, which can all but be made for free…
Below is some additional information from Wikipedia
Bio sand filters remove pathogens and suspended solids through a combination of biological and physical processes that take place in the biolayer and within the sand column. BSFs have been shown to remove 5.00-64.00% of heavy metals and 90.00-99.99% of turbidity and contaminants such as bacteria, viruses, and protozoa.
If you are interested in setting up your own bio-sand water filter, to run your collected rain water through, check out the link below.
