DIY Sulfur Denitrator

I read that article a while back and I guess I misread part of it. I have always used Kent Super Chelated Iron to catalyze the oxidation of hydrogen sulfide. It is good to know that GFO works as well.

Update again, things are going VERY fast

3/22 started cycle on bucket running full open nitrates at ~20
3/24 lowered flow to 1 dps
3/25 Effluent 0 bucket ~20 upped to 2 dps
3/26 Effluent 0 bucket ~20 upped to 4 dps
3/27 Effluent 0 bucket 10 upped to 6 dps
3/28 Effluent 0 bucket 0

3/29 tightened it all down and moved it onto the tank currently running nitrates of about 30, flow at 1 dps

I will preform a 50% water change this weekend as well to speed things up, and well its time for one anyway.

EnderG60------excellant, now watch your effluent for Nitrite as your Tank parms are much higher than your bucket, just before switching to the tank. I say this because while I intended to post my recent results I have run into a snag, but more about that when I figure out my next move. The good news in your case is that your tank Nitrates are "only" about 30 ppm.:mixed: :mixed:

Please post your results when you get them in the AM.

quick question so now that you have this sulfur denitrator you dont do water changes.
i know its kinda a newb question but is that the point.

nu2..............positively NOT, the "only goal" of sulfur denitrafication is just that, an efficent method of reducing or eliminating Nitrate. Water changes will always be required to replenish the " elements" that our live stock consume on an going basis.............:mixed: :mixed:
 
ok thats what i thought just wanted to make sure. cause i do water changes every 2 weeks when needed but am not religious and usually just every month.

should i go with a coarse or small ARM.

I thought I ordered coarse ARM but actually got small instead. I think the small is better for surface area, thus it is more soluble. The only drawback I can see with the small ARM is it tends to attach itself to my pump strainer inlet. This can be avoided by placing a sponge in your reactor above the ARM.

Update:

Alk - 8dkh stopped dosing extra alk, will add a lesser ml now
Ph - 8.2
NO3 - 2.5ppm :D

So thats 19 days on the tank and trates went from 25 to 2.5!!
 
Great thread!

Question, Im almost finished with my 6 inch OD reactor, only part Im missing is the blue foam layer. Where can I get a sheet of foam so I can cut 2 circles for my reactor, the ehiem 5 inch ones won't work for my tube size
Thanks
Erik
 
Question- I have mine set up in my sump. When I do water changes I clean (empty) out my sump for that short period of time. Will turning it off until my water change is done cause any problems? Or will I have to go through mini cycles every time I do a water change? If there may be issues with doing this than I'll just leave it running in just the sump and do water changes in just the main tank. I don't want to hurt the way the system is running now as I like having 0 nitrate issues :D

this is what I made
6 inch OD cast tube, 22 inches tall, eheim pump for recirc.

A while back someone mentioned foam from HD or Lowes. Check out around the pond section and they have two sheets for like $10 down here.

One sheet is black and one is blue.

Looking good. Replace those hoses with braided vinyl hoses so they don't kink. You can find them at HD, Lowes or Ace.

Thanks for the heads up on the hoses, I needed to go out and get some clamps anyways.

Another question:
Do I need a bleeder valve for gases when I have my return line at the top like I do? Won't the gases just come out with the efluent?
Just checking before I put her online

hi,,i have this diy unit running for a few month now,,,just want to know if my alk keep falling down all the time?? every time i bring it up and it keep going down,,,is this gonna happen for ever?? or does it stop some day,,,all i have is two part solution,,,

Yes, you do. Gases tend to lock or block the flow and give you and inconsistent effluent drip. The effluent line tubing should go deeper into the water column inside the reactor.
