Coil De-nitrator help

[jefft321]

I just got back in town and the feed pump for my coil denitrator failed. (it has a coil of tubing in side an acrylic cylinder with bioballs in the center).
I don't know how long there was no flow, but as expected when I flushed RO water through it I could smell the sulfur smell, what is the best thing to do now? I tried flushing it with 10 gallons of RO water, but there is still a smell. How much more should I flush it? Is there any harm in running it even if it still has the smell?

Well I am no expert here but I will try and help from experience of owning 2. First off not really sure why you may be getting a sulfur smell. Coil de-nitrators do not use sulfur nor should sulfur be added to them. They work by water moves so slow through the tubing that it breaks down the nitrates. I think the smell you may have is just the sludge inside that accumulates over the time. Personally those take time to cycle in so I wouldn't flush it to much or you may have to re-cycle the unit. I have since switched to a sulfur de-nitrator and when you start smelling sulfur it is because you drip rate is off. So if you have a sulfur unit check the drip rate. Also you may have a slight odor from time to time but not much which I have had. Hope that helps. If you need any more help give me a call!!!! Ben

Thanks Ben, I actually have the coil version that you used to have. I guess I would rate the smell as "like rotten eggs", I figured it's from the bacteria dying from lack of flow, I just didn't want to release any toxins into the water. I will hook it back up and see what happens.

You could just hook up your new pump and let the effluent run down the sink drain for a few hours or until it stops smelling bad. Then when you put it back on your system you can be relatively sure there is nothing bad going into your tank.
