Marble Test Water Treatment

The marble test and the langelier index.

Marble test water treatment.

Testing for oil based marble staining. A sample of water shaken with finely ground marble then filtered was analyzed for hardness and alkalinity before and after. There are two ways to determine calcium carbonate saturation. Pour a bit of water on the counter.

Put a few drops of mineral oil or water on your counter and leave it for a few minutes 4 minutes for the water and 10 for the mineral oil. Wipe up the liquid. Both the langelier index and the marble test are laboratory tests which can determine the degree of calcium carbonate saturation in the water at the treatment plant. This same test needs to be conducted for petroleum or oil based products you may use on a regular basis.

1 4 cup should be enough note the time that you placed the water on the counter and time the water to see how long it takes to absorb the granite will darken. Water which is just saturated with calcium carbonate or which is slightly supersaturated with calcium carbonate is considered stable and safe to release into the distribution system. Perform a simple water test to see if your granite countertops need to be sealed. Test the marble with water or mineral oil.

In this condition it will neither dissolve nor deposit calcium carbonate. Years ago the marble test was used as a measure of a water balance. To conduct this part of the test follow these steps.
