The Oxygenator, how effective is it?

  1. 1. The Oxygenator How well does it work?
  2. 2. <ul><li>The Oxygenator is battery-powered device purported to increase oxygen in livewells. </li></ul><ul><li>According to the manufacturer, it splits water (H 2 0) into its two basic elements, </li></ul><ul><li>hydrogen (H) and oxygen (O), resulting in formation of dissolved oxygen. </li></ul><ul><li>More information about the device can be found at the manufacturer’s website: www.keepfishalive.com </li></ul>
  3. 3. <ul><li>Both the Portable and the Pro Livewell Flush Mount models of the Oxygenator were evaluated. </li></ul><ul><li>The Portable model was used in a 2006 Skeeter and the Pro Livewell Flush Mount was installed into a 2008 Skeeter. Both boats had two independent 15- gallon capacity livewells. </li></ul><ul><li>For each boat and Oxygenator combination, six one-hour trials were conducted with oxygen level measured every 10 minutes. </li></ul><ul><li>Two trials were conducted for each of the following: </li></ul><ul><ul><li>Recirculation system only </li></ul></ul><ul><ul><li>Oxygenator only </li></ul></ul><ul><ul><li>Oxygenator and recirculation together. </li></ul></ul><ul><li>Livewells did not contain fish. </li></ul>
  4. 4. <ul><li>Portable Oxygenator Test Results </li></ul><ul><li>Recirculation produced substantially more oxygen than the oxygenator and raised oxygen level to near saturation in 10 minutes. </li></ul><ul><li>Using the Oxygenator together with recirculation increased oxygen by only 3.8% over recirculation only. </li></ul>Water temperature = 75 F Oxygen saturation = 8.4 PPM
  5. 5. <ul><li>Pro Livewell Flush Mount Oxygenator Test Results </li></ul><ul><li>Oxygen increased minimally using recirculation and recirculation together with the Oxygenator. Oxygen did not increase when using the Oxygenator only. </li></ul><ul><li>Using the Oxygenator together with recirculation increased oxygen by only 3.8% over recirculation only. </li></ul>Water temperature = 68 F Oxygen saturation = 9.1 PPM
  6. 6. Conclusions and Recommendations <ul><li>The Oxygenator produced less oxygen than standard recirculation on two Skeeter Boats. </li></ul><ul><li>The Oxygenator increased oxygen by only 3.8% when used together with recirculation. </li></ul><ul><li>If using the Oxygenator, run recirculation system continuously to maintain sufficient oxygen in livewells. </li></ul>
