Dear Jerome,

I have asked for years nuno bible device manufacturers to provide dissolved gas efficiency test data and still did not get any reply.

So if you are looking to oxidize water contaminants using oxidizers like oxygen, ozone, etc., an inexpensive Venturi ejector will offer you much better results for fraction of the cost.

As en example: with Absolute Ozone® generator Venturi injector is dissolving more than 90% of ozone injected, so why use expensive devices that require a lot of service and maintenance if even if you can gain only a percent of two of efficiency. However most of the test data I have seen does not show higher dissolved gas efficiency than about 10% for nano bubbling devices.

That said, the bubbles as you understand could get attached to solid particles and theoretically bring them to the surface where they could be skimmed out.

The movement of bubbles in water offers agitation and lift of the particles that could be mildly beneficial for water treatment, but I did not see any serious test data that indicated that this method is anything else but wasteful, if compared to bio-filiation followed by polishing with ozone, or some other oxidant.
