| I am not the best person to answer your question, Monscine. I am hoping one of our filter gurus will come along and give you some direction.
But, if you are planning to move 22,000 gallons per hour through the filter system, I will say that you are going to need a bigger vortex than I have ever seen, or a bunch of them. I am currently moving approx. 6,000 gallons per hour through a 50+" vortex. It does a good job, but not as good as I would want if I was relying on brushes in the next stage. I certainly would not want to move any more through it. Vortex settlement is more efficient than a settlement chamber such as Dwight shows in his drawing, but still depends on relatively slow water flow for debris to settle out.
If you were referring to the dwell time in the filter system, think again. You want to run the volume of the pond through the system within two hours. I try for a 45 minute turnover of the pond volume, and use multiple separate systems to accomplish that. |
