Abiotic nitrate reduction

[russiangoat]

Hello,

I am looking for information on converting nitrate to inert nitrogen gas (denitrification), without harmful byproducts, for use in treating domestic wastewater. Most processes I've been introduced to use biological means to accomplish denitrification, so I was wondering if anyone could pass on information for a chemical, or possibly metal filing technology. The idea is that biological processes need to be attended more than a straight chemical process, so a non-biological process would be much more appealing for clients that cannot attend to the treatment on a consistent basis.

Thanks in advance, for any help.
