Very interesting and I'm sure quite effective. Albeit a little antiquated.
I'm not sure how many here will want to go through that much trouble to clean it. The Doc and Skippy filter require 45 seconds every couple weeks and we do not have to move any pipes or fittings, get our hands wet or have a vacuum turned upside down as a blower to do it. I need only 50 gallons of water to get mine clean and that is what is dumped when I open the 2 Inch dump valve. After 45 seconds, I close it and I'm done.
Water is always crystal clear and bio perfect. If you are ever in the San Diego area, stop by, I would be happy to show you the trouble free system used here.
Another breeder just north of here who has 80,000 Koi uses the same method I use. His family in Japan that have 250,000 koi are using the same as his. These are, of course much larger in scale.
