Counter-current skimmer allowing an injection of ozone.

Skimming is a process of removing unwanted substances in the water from the basin. This means removing them from the water and not simply transforming them like a biological filter.

What are these substances?

These include, among others, amino acids, lipids, phenolic compounds, proteins, in short organic carbon molecules.

Proteins and phenols are substances that color water in yellow and degrade the quality of the water in the basin. The structure of these substances has a carbon-based end which does not like water (hydrophobic) and a different end (N or O) hydrophilic (attracted by water).

It emerges that these molecules are surfactant: they will therefore be attracted by an interface (*) which allows the hydrophilic part to remain in the water while its hydrophobic opposite touches an air bubble. The skimmer makes it possible to exploit this peculiarity ... it is the principle of skimming!

(*) Interface: any separation between air and water. Examples, bubbles, surface of a pool, drop of water ... reason why the interfaces are often carriers of visible pollutions. One understands the utility of a skimmer (surface of basin) ...

Operation

The operation of the skimmer is very simple: the air blown into the column attracts those molecules that rise with the bubbles. In the upper part of the skimmer, these bubbles eventually create foam that overflows into the cup under the pressure of other rising bubbles.

The dirt is exported to the bucket: water is not only cleared of the molecules mentioned above, but also of MES, traces of possible drugs, micro algae ...

The proposed skimmer model is of countercurrent type: water and air circulate in opposite directions: the water goes down into the reactor while the air is diffused at the bottom of the column. The contact time of 1 minute allows a good yield to this reactor: this allows the molecules to be attracted by the rising bubbles.

Ozone destroys the substances that color the water and breaks up the biggest molecules: just like the skimmer that allows them to be switched off ... two distinct actions for a device twice as efficient!

The skimmer can function without ozone, it remains an excellent device able to partially participate in the discoloration of the water and allowing a good oxygenation.

With ozone injection, we can increase the efficiency of the device and increase the oxidative power of the pelvis: with the control of a regulation (Redox sensor) you are certain to increase the quality of the water in your pond! There is no other method more effective.
