Method of making a filter with ground animal bone granules and filtering therewith
The present disclosure provides a water filter device generated using animal bone. In some embodiments, the water filter device comprises a tube containing a series of layers of animal bone granules.
1 . A method of generating a water filter device comprising:
(a) obtaining an animal bone;
(b) boiling the animal bone to remove oil;
(c) drying the animal bone;
(d) grinding the animal bone to bone granules;
(e) sieving the bone granules into:
coarse size granules having a diameter of 0.4-0.8 mm,
medium size granules having a diameter of 0.2-0.4 mm, and
fine size granules having a diameter of less than 0.2 mm;
(f) obtaining a tube having a top end and a bottom end, wherein the bottom end is covered with a water permeable barrier; and
(g) placing the bone granules in the tube, in an order from the bottom end of the tube to the top end of the tube:
a first layer of coarse size granules,
a layer of fine size granules,
a layer of medium size granules, and
a second layer of coarse size granules.
2 . The method of claim 1 , further comprising before step (b) a step of cleaning the animal bone to remove residue on the animal bone.
3 . The method of claim 1 , further comprising before step (b) a step of cutting the animal bone into pieces.
4 . The method of claim 1 , wherein the water permeable barrier is a cloth.
5 . The method of claim 1 , wherein the tube is made of polyvinyl chloride.
6 . The method of claim 1 , wherein tube has a length of about 3.5 inches.
7 . The method of claim 1 , wherein the animal bone is grinded by a bean grinder.
8 . The method of claim 1 , wherein the animal bone is grinded by mortar and pestle.
9 . The method of claim 1 , wherein the animal bone is cow bone, lamb bone or pig bone.
10 . The method of claim 1 , wherein each layer of bone granules has a thickness of about 0.8 inch.
11 . A method of filtering water comprising:
obtaining a water filter device generated according to the method of claim 1 ;
pouring water from the top of the water filter device; and
collecting filtered water from the bottom of the water filter.
12 . The method of claim 11 , further comprising boiling the filtered water.
13 . The method of claim 12 , wherein the filtered water is drinkable.
