100-Year-Old Way To Filter Rainwater In A Barrel. During our boiling, broiling, blistering summer of 2012 here in the Missouri Ozarks, water was a topic of conversation wherever we went.
Creeks and ponds dried up (some never recovered) and the water table dropped, forcing a few neighbors to have their well pumps lowered or to even have deeper wells drilled. Many folks shared memories of rain barrels, cisterns, hand pumps and drawing water with a well bucket as a child, usually on grandpa and grandma’s farm. Some said they’d never want to rely again on those old-time methods of getting water. But, at least they knew how it was done. It seems we have lost much practical knowledge in the last 50 or so years because we thought we’d never need it again. A tattered, 4-inch thick, 1909 book I happily secured for $8 in a thrift store reveals, among umpteen-thousand other every-day skills, how to make homemade water filters.
The “wholesome” observation applies to plants, too. 100-year-old instructions Free online reading. DIY: Field-Expedient Water Filter. We all know how important water is in a survival situation.
Without it, you don’t stand to last long. One question I get on this blog from time to time is: “If I were stuck out in the bush how would I go about making a field-expedient or homemade version of a water filter similar to the commercial varieties made by companies like Katadyn or Berkey.” I assume they mean making a filter that can eliminate biological nasties like Cryptosporidium or Giardia. If that’s what you’re after, boiling is the only tried and true method of water purification out in the bush. The Limitations and Uses of a Field-Expedient Water Filter In reality, there is no way to get a field-expedient water filter to replicate the filtration performance (in terms of microorganisms filtered out) that you’d get out of a commercial one, but it DEFINITELY doesn’t mean these filters are useless.
And this, my friends, is where a field-expedient filter would come in real handy. Emergency Water Filtration Devices. Slow Sand Filtration For Water Treatment. By Art Ludwig Background Although slow sand filtration technology has been widely used in Europe since the early 1800s, its current use in North America has been primarily limited to smaller communities in New England.
With the recent issuance of the Surface Water Treatment Rule by the U.S. Environmental Protection Agency and new filter requirements for all surface water systems to ensure removal of Giardia cysts, there is renewed interest in slow sand technology. Although extensive research has been conducted over the past ten years documenting the efficacy of this technology for removing cysts and other particles, no publication has provided the appropriate level of engineering information to design, construct, and operate a slow sand filter to meet the level of treatment performance specified in the new regulations. Slow sand filtration technology is especially appropriate for small communities that are required to use filtration to comply with new regulations. How SSF works Housing.
Improvised Rapid Sand Water Filter. -Plastic bag, Birch bark, Poplar Bark etc. -Small Pebbles? -Sand? -Non poisonous Grasses -Charcoal leftover from a fire, or coal from a grill.? -Container to collect water as it drips out of filter. Creating an Improvised Rapid Sand Filter. Step 1 If you are using bark you need to cut out a square off the tree, and tie it into a cone, or funnel shape. Step 2 Gather materials together and begin to layer inside them inside the bag or bark cone. 1st layer should be non poisonous grass webbed or woven to catch particulates and some of the taste of the second layer. 2nd layer needs to be coal. 3rd layer Sand. 4th layer pebbles. 5th layer sand. 6th layer pebbles. 7th layer webbed or woven grass.
