An extremely powerful oxidizing agent, ozone will essentially “bleach” your seawater clean when used in a controlled environment in a safe and effective manner. Since the amount of ozone needed to clarify water is significantly less than that needed to kill most pathogens or other organisms, the usefulness of ozone extends even to systems that employ “probiotic” means of nutrient control. Coupled with an efficient protein skimmer, ozone can help improve water quality by breaking down large organic molecules into components more suited to skimming or usable by bacteria. Ozone users frequently report an increase in skimmer productivity and almost always better water clarity and overall system health.
The AVAST Mutiny ozone reactor series is designed to react seawater in a pressurized, ozonated air environment. The efficiency of this process is maximized by balancing water throughput with contact time as water is sprayed over a bed of thin HDPE ribbon media in an atmosphere of ozonated air. The high surface area of this media allows much better gas exchange and oxidation of organic material than simply bubbling ozonated air through a column of water, as when using ozone in a protein skimmer. The media also increases dwell time, since it creates a circuitous path for the water to reach the bottom exit.
Our reactor mixes water and air via ozone safe Kynar venturi and sprays this mixture into a diffuser chamber designed to distribute water over the ribbon media. Once the water reaches the bottom, it is forced up the center tube and out to the carbon post-filter where residual ozone and oxidation byproducts are removed. This path of water flow, coupled with the sizing of the fittings and pipe, is what creates a “pre-set” internal pressure, eliminating the need for an expensive stainless steel pressure gauge. All of our reactor sizes, when driven with the recommended water pump (or flow rate), will run with an internal pressure around 3psi.
Even though the reactor uses a venturi to mix air and water, the reactor still requires a quality air pump to assist the venturi. The reason for this is since the reaction chamber is under pressure, there is not enough pressure differential between the two sides of the venturi to allow adequate air intake from the speedup of the water through the venturi nozzle. We recommend a Luft pump or similar pump capable of producing at least 2 scfh (60lph) at 3psi. It is possible that using a stronger water pump would provide the necessary pressure in the venturi to eliminate the need for the air assist, but such a pump would require a lot more electricity, where a Luft pump requires very little power to do the same thing.
Included with the reactor is an accurate Dwyer airflow meter. During testing, we found this device to be invaluable in determining how much ozonated air was moving through the reactor. Coupled with a performance curve of your chosen ozone generator, the air flow meter will tell you how much ozone you are using to achieve various water quality goals. For example, you may find that 100mg/hr at 2scfh will remove any visible yellow tint from tank water. Below, we give general guidelines for dosing ozone but since each system is different, some experimentation may be needed.
