Method of Reverse Osmosis Water Testing

Reverse Osmosis water purification process is a simple and straightforward water filtration process. It is accomplished by water pressure pushing tap water through a semipermeable membrane to remove impurities from water. In this process, the dissolved inorganic solids are removed from the water. Few impurities that are found in tap water can be removed by the use of RO. Impurities such as Fluoride, Lead, Chlorine and chloramine, Pesticides, Detergents, and more, Nitrates and Sulfates.

Just because of modern chemistry, we able to found thousands of chemicals in water even at extremely low concentrations. There are a number of lists available, and the majority of the tests required lab facilities. The tests that are required to motored the quality of water are divided into three categories:

Test Strips

As the name tells us that this test is considered of strips that change color to bring indication of specific chemical in water. In this test, you need to dip the strip in the water, and after some time, the user can compare the test strip color with a color chart to read the concentration of the chemical. These kits are easy to use but less accurate than other methods.

Color disk Kits

This test is available for a wide range of chemical tests. In this test the user adds a powder packet for a few drops of a liquid reagent to a water sample in a reusable plastic tube. The user then places the sample tube in a small plastic viewing box. This viewing box contains a plastic disk with a color gradient printed on it. Color disk kits typically have multiple steps often include prescribed wait times, so they are little more complicated and costly, but generally more accurate.

Handheld digital instruments

Digital meters are available that are used for water testing. They provide the most accurate results as compared to the other two testing methods, but this method is also expensive as compared to previous ones discussed above.

Depending on local conditions and on the focus of a water quality monitoring project, more chemical tests can be added. The majority of tests are those that are being performed in a laboratory given current technologies.
