SUMMARY:Slow Sand Water Filter discussion.
DESCRIPTION:Let's talk about Slow Sand Water Filters. I have basic kno
 wledge of how they work and I am in process building my first one.\nTh
 ey produce very clean water at about 10 gallons per day. The supply of
  raw water must be free of sediment for best results.\nI will have pic
 s of my system in progress and I would like very much to talk to you a
 bout how they work.\nThese filters have an active \"Bio Layer\" of mic
 roorganisms 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 mu
 st 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 wa
 ter until the bio layer is established. The output water should be tes
 ted before you start drinking it.\n\n\nFor more information visit http
