Oil sands process and production. Oil sand is a mixture of bitumen, sand, clay and water. Because it does not flow like conventional crude oil which is a liquid, it must be mined or heated underground before it can be processed. Once the bitumen has been extracted, we upgrade it into higher-value synthetic crude oil, diesel fuel and other products.

The filter sand used in rapid sand filters is manufactured specifically for the purpose of water filtration. Most rapid sand filters contain 24-30 inches of sand, but some newer filters are deeper. The sand used is generally 0.4 to 0.6 mm in diameter. This is larger than the sand used in slow rate filtration.
