So NNR stands for Natural Nitrate Reduction...

How you do this??? DSB ...LR......????

[Achilles Tang]

????? Do what?

[Phang]

Achieve NNR status...

[Achilles Tang]

oh... yes... both will are NNR methods... if you set it up right.

Howdee,

Thanks Archilles Tang, this is indeed very helpful. I was a bit lost with all the jargon, but not anymore.

Cheers

How about, FR? had a bit difficult time deciphering that before... i found it once and now i forgot again...
