Activated is sometimes substituted with active. https://padlet.com/diverkathleen/ztbq5w7b1ji/wish/341381415 https://en.wikipedia.org/wiki/Activated_carbon]]> 2019-03-14 15:22:54 UTC https://padlet.com/diverkathleen/ztbq5w7b1ji/wish/341381415 Gravel https://padlet.com/diverkathleen/ztbq5w7b1ji/wish/341381849 Gravel is a loose aggregation of rock fragments. Gravel is classified by particle size range and includes size classes from granule- to boulder-sized fragments.

The fiber is almost pure cellulose. Under natural conditions, the cotton bolls will increase the dispersal of the seeds]]> 2019-03-14 15:25:34 UTC https://padlet.com/diverkathleen/ztbq5w7b1ji/wish/341383075 Diatomaceous earth is a type of powder made from the sediment of fossilized algae found in bodies of water. Because the cells of these algae were high in a compound called silica, the dried sediment produced from these fossils are also very high in silica. These deposits are found all over the world. The ancient Greeks used diatomaceous earth to make building materials, like bricks and blocks. Later on it became popular in Europe for various industrial uses. https://padlet.com/diverkathleen/ztbq5w7b1ji/wish/341383778 2019-03-14 15:26:44 UTC https://padlet.com/diverkathleen/ztbq5w7b1ji/wish/341383778 Gravel https://padlet.com/diverkathleen/ztbq5w7b1ji/wish/341384206 In slow sand filters, the gravel is normally on the bottom layer and is used as channels for filtered water to make it to the outlet lines. ]]> 2019-03-14 15:27:22 UTC https://padlet.com/diverkathleen/ztbq5w7b1ji/wish/341384206 carbon Filter https://padlet.com/diverkathleen/ztbq5w7b1ji/wish/341384480 Diatomaceous Earth]]> 2019-03-14 15:27:47 UTC https://padlet.com/diverkathleen/ztbq5w7b1ji/wish/341384480 reason for carbon filter https://padlet.com/diverkathleen/ztbq5w7b1ji/wish/341384951 https://learn.allergyandair.com/activated-carbon-filters/]]> 2019-03-14 15:28:33 UTC https://padlet.com/diverkathleen/ztbq5w7b1ji/wish/341384951 Cheesecloth https://padlet.com/diverkathleen/ztbq5w7b1ji/wish/341384982 Cheesecloth is a loose-woven gauze-like carded cotton cloth used primarily in cheese making and cooking.]]> 2019-03-14 15:28:35 UTC https://padlet.com/diverkathleen/ztbq5w7b1ji/wish/341384982 Why we useDiatomaceous Earth https://padlet.com/diverkathleen/ztbq5w7b1ji/wish/341392968 When taken by mouth, diatomaceous earth is used as a source of silica, for treating high cholesterol levels, for treating constipation, and for improving the health of skin, nails, teeth, bones, and hair.These microscopic organisms such as plankton or algae have the unique ability to extract silica from water to produce a microporous exoskeleton.]]> 2019-03-14 15:42:39 UTC https://padlet.com/diverkathleen/ztbq5w7b1ji/wish/341392968 Diatomaceous Earth is used to filter out biological contaminants such as bacteria and soil. diverkathleen https://padlet.com/diverkathleen/ztbq5w7b1ji/wish/341404810 2019-03-14 16:03:38 UTC https://padlet.com/diverkathleen/ztbq5w7b1ji/wish/341404810
