DIY denitrator any risk?

Thanks

i have the 2nd edition and its missing alot of the good stuff on nitrates !!


also Biological Nutrient Removal (BNR) Operation in Wastewater Treatment Plants (Wef Manual of Practice)"
Water Environment Federation


looks like a good title.havent seen it yet

John,
I would be interested in any results you find. I have access to Australian University databases and journals and there is a large mining industry presence in Australia where they also wish to reduce aqueous nitrate in effluent.

Perhaps you should use plants to remove nitrate? Aquatic Hornwort and edible Corn are listed with Hornwort being particularly efficient at nitrate removal.

thanks for the link


i am leaning towards a large bio media filled anoxic filter...still checking..........vrs traditional deep sand bed....

I thought about this a few years ago and put it in the too hard/water changes are cheap~easier basket. Mostly hesitant because I have lost valuable fish from hydrogen sulphide poisioning before and the scary part is there is little or no warning.

On most of my central filtration fish systems I incorporate an external tank (outside) which I take off the system - turn off tap- to culture green water or sometimes a live baby brine shrimp culture. Turning it back on slowly is an easy way to feed and gives indoor fish great natural colour. I have thought about using this method for lowering nitrate and then turning it back onto the system as a gradual water change source. That way I could put some canaries (sensitive fish) in to make sure all is okay before adding into the main system. What I ended up doing was installing large rainwater tanks instead. Its annoying because the technology for nitrate removal is available but too expensive or impractical to implement at the moment. I think live plants are the safest and easiest option but I am very much interested in your success.

1) WHAT WAS THE SOURCE OF SULFUR ???

2) i am currently changing so much water Los Angeles in now in a drought

I do not think a coil denitrate filter will have an effect on a large 8' over stocked tank. I do not even think you would be able to see the difference on a test kit.

I know a guy who made a 32' 1'' pvc denitrate filter and an existing 9' section.

If you are worried about ammonia and nitrite leaching back into the tank you can install a bio wheel or a small W/D tower to the output.
