Sulfur DeNITRIFIER DIY!!!
Does any body have any diy sulfer denitrifier plans. Thanks

Run line between 3 'add-on' RO canisters, plus a feed line, and a drain.
Hook a small maxijet up to the feed line, with a flow restricter valve in the line. An aqualifter might work here too, though Ive never tried it- I think the flow would be too slow though. 1st canister: Sulfur media 2nd canister: Crushed coral/Calcium reactor media (to adjust pH) 3rd canister: Granular activated carbon (to help remove hydrogen sulfide) Note, you can get refillable media canisters (like what DI media comes in). I would suggest using those to put your media in, just to prevent any particles from clogging up the lines. Test the effluent coming out of the reactor after a week or two; if you still have high nitrates, turn the restricter valve and reduce the flow through the reactor. If it comes out clean (or real close to it) then leave it be. One thing to note, I think its better to run the effluent into a sump, rather than directly into the tank. That will allow for more aeration and reduction of any potential Hydrogen sulfide produced by the reactor. Its worked pretty well for me and for people Ive put them together for anyhow.

Hormigaquatica-
How high were your nitrates initially that prompted you to put this online? Thanks!

You know, its been running for a while, and I really dont remember. The last one I helped someone hook up dropped his Nitrates from 40ppm to 9 within 2 weeks if I remember correctly. (Total volume on that system is over 200g)

yeah mine are at 70!!!!Not good

Can you give us an estimate on the flow rate we should end up
with? Will it be a drip or slow dribble, or more like several gallons/hr? |

If you go back and read, it really will depend on how its effecting your nitrates.

It will be a fairly slow stream. If youve ever run an RO unit then you will be familiar with how fast the waste water drains out; itll be a flow similar to that. But it really will take some fine tuning- you will want the fastest flow possible while still giving it just enough time to polish off the nitrates.

Yes, I did read that. I was just wondering what flow rates you
typically would end up with. I wondering if instead of feeding it with a powerhead I could instead feed it by gravity from the main tank. Quote:

Question: I've seen reports of these sulfur reactors producing
smelly hydrogen sulfide at times. What causes this? Is it from adjusting the flow rate? Should it not happen with a properly functioning reactor? Thanks! Quote:

Thanks. I'm going to try a gravity feed first. This would be from
a siphon off the main tank, roughly 5' above the sump. I'll let you know how it works. Another question: The media -- meaning the sulfur, crushed coral, and carbon; do they need to be changed, and if so how often? Thanks! Quote:

Hormigaquatica,
I notice that your RO/DI canister design does not use a recirculation pump, while it looks like the commercial products all do. Can you explain what the pump does and why it's not necessary? Thanks for all the great info! |

Some of the premade ones have a recirculation pump on them just to extend the amount of time the water spends moving through the media. I didnt bother putting one on mine because I just didnt find it necessary; you can control the dwell time by using a flow restrictor on the feed or drain line. I will say that restricting the flow may shorten the lifespan of your feed pump (if youre using one). If you had a feed pump running full tilt, then depended on a recirc pump to increase dwell time, the feed pump would probably last a bit longer. But- I just wasnt that concerned about the $20 MaxiJet.. lol

Hormigaquatica.... can you post a pic of your diy DeNITRIFIER please

#22

Sorry- took me a couple days to get a shot This isnt my own, its one of the first ones we played with at work- it handles a 1000g system fully stocked pretty well.

Any idea if this is better or more efficient than a standard coil denitrator?
|
#24
|
|||
|

Really couldnt say- Ive never used one of the coil types. I would assume the sulfur denitrator would be more efficient because you are providing a food source and oxygen depleted environment for the anaerobic bacteria (the sulfur coupled with slow water flow) rather than just the anaerobic conditions you get in a coil. But like I said, thats just a speculative WAG.

That was very inventive. I like it. In the picture, the media isn't in canisters. I'm thinking the canisters will require the fluid to flow through the media instead of circulate over the top of it, as it appears in that picture.
I wouldn't mind making one myself. Might have been nice to do that before I ran AZNO3 in my tank.
