Justification of tests

Since the ions contained in salt water and the radioactive ions, which have been included in the test program, are smaller than 0.001 microns (one micron is 0.000001 meter) and thus smaller than any other types of particles, the tests conducted with salt water and radioactive ions prove that all types of particles are removed.

Tests with bacteria have been conducted to control that live organisms do not behave differently in the process compared to other matter tested. Bacteria are around 1 micron in size. There are known smaller living organisms. Virus, for instance, are as small as 0.01 micron. However, not even unknown organisms can be smaller than an ion. An ion consists of one or several atoms.

Chlorine, trihalomethanes and radon are gases commonly found in drinking water. The former in municipal water and the latter in well waters. Total removal of these gases imply that also other gases are removed completely.

Total efficiency

All gases (or any volatile matter) will be removed in the same way and all material (or any non-volatile matter) will be removed. And there is no other type of matter than volatile and non-volatile. Therefore we can say: no matter what your contaminants, they will be removed.

Detection levels

The contracted laboratories have used state-of-the art measuring methods. Even though all test results are zero, i.e. below the detection level (measuring capacity) of the equipment presently used, there may be some undetected traces of the tested elements in the purified water. As soon as more sophisticated test methods appear on the market, HVR will make new tests.
