nitrate removal

[sjnovakovich]

On a 55 gal., what about setting up a sump and putting a polyreactor in it that contains nitra-zorb? It's an involved solution, but I think better than RO because you don't have to replace the good stuff that RO would remove.

Well, a bottle of RO-Rite is a couple bucks.. lasts a long time, $100+ for the RO/DI, using it just for PWC then filters m a y b e once a year + some wasted water unless you collect and use it for plants etc.

Now lets cost out the sump/over flow/return pump/plumbing option?

Remember each PWC the OP is adding 40ppm of nitrates.. over and over and over and over and over. ..... Did I say "and over"?

Plus what's created naturally



From the CDC:

nitrate concentrations can be reported either as nitrate (NO3) or as nitrate-nitrogen (NO3-N). Be sure to know which reporting system is being used since the acceptable concentrations of each are considerably different. If the lab reports its results as nitrate-nitrogen (NO3-N), the drinking water quality standard is 10 milligrams per liter. The standard is 45 milligrams per liter if the results are reported as nitrate (NO3). A milligram per liter (mg/l) is also equal to a part per million (ppm). If you are unsure of how to interpret the report, contact the lab, the local Extension office, or health department. It is important to check the lab report carefully because the two systems of reporting are frequently interchanged.
