Event Description

Let's talk about Slow Sand Water Filters. I have basic knowledge of how they work and I am in process building my first one.

They produce very clean water at about 10 gallons per day. The supply of raw water must be free of sediment for best results.

I will have pics of my system in progress and I would like very much to talk to you about how they work.

These filters have an active "Bio Layer" of microorganisms that grow in the top few inches of the sand in a 55 gallon barrel. This bio layer must be kept alive and well fed for the filter to work. That means that once you get the filter set up, raw water must slowly trickle into the filter 24/7. After 3 weeks of operation the water output should be very clean. You can't use any of the output water until the bio layer is established. The output water should be tested before you start drinking it.
