Well I promised to do his when I posted the larger version and I finally got the parts and some time.
For those who didn't see the first thread, http://www.plantedtank.net/forums/eq...n-reactor.html
I wanted to find a more efficient way to use Purigen with my filter systems. The "bag" approach tends to channel flow around the exterior and I would always end up with some dark regions and lot's of white purigen that hadn't been exposed to impurities.
A fluidized bed approach is ideal but i couldn't find a good reactor that could work with such small beads. I built a larger reactor that worked with my high flow filter systems for my 90 gallon and for my 60 gallon. These have been working very well. Here is the original thread
So The current reactor is smaller and designed to work with my 12 year old Eheim 2213 which is on a 10 gallon tank.
- Pentek 2 and 3/4" by 5" water filter housing with 3/8" inlet and outlet
- Two 3/8" threaded by 1/2" barbed adapters
- A 2 and 3/4" diameter by 5" pleated polypropylene filter cartridge. This is 30 micron as I could not find a 50 micron cartridge to fit the housing
- about 200ml of purigen - this was too much. I will try 100ml next time to get all of it fluidized
In action. The Purigen is wedged into the pleats, kind of like a diatom filter. The remaining material is split - half in motion and half down on the bottom. I'll use less next time
