Bio-Sand Water Filter Description

  Bio-sand filtration is a simple, cheap and effective means of removing disease-causing micro-organisms from contaminated water. It is a modification of traditional slow Filtration Technology that has been around for over 150 years. While the traditional slow-sand filter technology requires a continuous flow of water, this unique design was developed specifically for intermittent use in the households of developing countries where a continuous supply of water is usually difficult to maintain. It can be constructed out of low cost materials that are available world wide. This filter has no moving parts and is very low maintenance. Bio-sand filters have been shown to almost entirely remove harmful microbes found in water. This filter design has been introduced in more than 30 countries, by a variety of organizations and people.

So How Does it Work? ---CONTINUED---

  Here's some info to consider about filtering through fabric that I had saved from the old APN site. Another 'Oldie but Goodie' rescued!

Filtering Through Fabric
From American Preppers Network

tigger2:
You can use a lot of stuff to clean up the water before you run through your filter. You could run it through a towel, cheese cloth or a pair of jeans. The cloth would act like a filter and get a lot of the big stuff out.

 Muzhik:
If you're going to use a cloth pre-filter, some things to keep in mind:

   1. The cloth should be 100% cotton with a medium-to-tight weave. Old tee shirts work really well for this.
   2. You should fold the fabric so that the water will go through 4 layers.
   3. You should use the cloth ONLY ONCE. After that the cloth needs to be washed and then dried in the sun before being used again.

This comes from some research in India, where public health officials were trying to find out why some families got sick drinking the river water and others didn't. It turns out the women who collected the water for the families that didn't get sick were running the water through folded parts of their cotton saris. The researchers found out that filtering your water through 4 layers of cotton cloth would remove up to 99% of biological contaminants. This means you can use this technique in an emergency. Just remember: the cloth needs to be dried in the sun to ensure any remaining germs, etc. get killed by the UV.

Large Quantity Home-made filter:   You can also make a wonderful and inexpensive filter yourself that will filter about 1000 gallons of water.  Get a 4-6 gal. bucket and cut a hole in the side as shown below.  Place a piece of cheesecloth or a piece of clean bed sheet over the top with a dip in the center.   Tie a cotton rope (cotton clothesline works great) around the top of the bucket under one of the ridges to hold the material in place.  Layer sand and activated charcoal in the bucket = 7 layers, 1/2” thick each.  Place a bowl or pan inside the bucket under the material to catch water.  Pour water into the bucket over the sand and charcoal layers.  Let the water filter through to the collecting pan underneath.   Empty the bowl occasionally.  This device will filter about 7-8 gallons per day.
   The finer the sand, the better:  (Lowe’s, Home Depot);  and you can get activated charcoal at Pet Smart in the aquarium section.  You’ll need about a quart of charcoal and about a gallon of sand.  (Charcoal = about $4-9/ quart, and sand = about $4-6 for 100 lbs! -- it’s “dirt” cheap!)

**Note:  radioactive fallout can be filtered out of water.  NEVER boil water with fallout in it before filtering.
