In the previous pages, we explain that the organic matter that is decomposed by oxidizing power of ozone.
Here, I will discuss pond activated carbon adsorption to adsorb organic matter is decomposed.

Just break down organic matter in the ozone, it is still remaining after decomposition was suspended.
What's activated carbon?
I cleaned in that there are many things very fine holes of less than 2 nanometers, has been decomposed into its hole is captured.

In the water purification plant what is called a granular activated carbon, of about 0.5 cm cylindrical vertical have been used.

Isn't the effect of activated carbon falls?

Of course, that is a hole, activated carbon purification capacity is going down with use.
Therefore, the water treatment plant We have been revived by the effect of reversing the water from the bottom of the activated carbon injection on a regular basis, the "backwash".
