mnestroy, I just finished reading this old thread too and I've decided to inject my Enaly via a maxi jet (through the extra fitting they supply, which is supposed to bring air into the maxi) into a PhosBan reactor full of carbon. Doing it this way tho you'll have to have an Enaly or rig an air pump to the ozone.
I'll post in a couple of days and let you know how it works.
Injecting air/ozone into a fluidized bed filter will attach bubbles to the carbon, causing them to float out of the column.
You can inject ozone with a pump venturi, but it is less efficient than doing so with a protein skimmer where the gas is much more stable and has longer dwell/contact time.
Freshwater applications are suitable for this method of introduction, as ozone goes into solution readily. It's typically done in commercial systems with long runs of PVC pipe, with a long contact time. Saltwater has a lot more dissolved solids, so it's ion-rich nature causes small, stable bubbles. These stable bubbles take to long to pop, so air injection should be limited to protein skimmer use.
Using ozone with protein skimmers compromises the integrity of the bubbles, as the bubble surface losses stability. Fractionation is less effective due to the ozone, but overall skimmer efficiency is greatly improved, as organics are oxidized. I can really see a difference in the colour, consistency, and yield of the skimmer when ozone is added.
I believe I read somewhere that it's a fire hazard to expose dry carbon to ozone. Perhaps this is only in great quantities.
A gas reactor is your only other option for ozone introduction. gas reactors are used for Co2, oxygen, and ozone. They are relatively small, plumbed inline or on a bypass, and resemble a trickle filter due to the bioball contact media. The reactor fills and drains in a continual ebb and flow cycle. Some reactors are pressurized enough so that they can maintain a consistent water level at the bottom of the reactor.
. I will use the eheim to feed the reactor
