Hi There,
So we are on the cusp of opening and i sent 2 water samples to ward labs. 1 bottle of city water before it hits our 6 foot tall, 2 foot wide Charcoal bed, and 1 bottle after it had been filtered. We used 6 Cu Feet(165 pounds) of Bulk Coconut Carbon Drinking water grade 12X30 on top of 150ish pounds of Peastone in the filter.
Unfiltered Sample
pH 7.5
TDS 396
NA 98
K 3
CA 17
Mg 6
Total Hardness 68
Sulfate 5
Chloride 159
CO3 <1.0
HCO3 41
CaCO3 34
P 0.02
Filtered Sample
pH 9.4
TDS 542
NA 88
K 112
CA 9
Mg 4
Total Hardness 39
Sulfate 4
Chloride 146
CO3 20.1
HCO3 152
CaCO3 153
P 2.64
As you can see the changes between the 2 samples there are some expected loss and then some very unexpected increase in K, Cl and Bicarb. I called Ward Labs and he believes something may of been infected with K leading to the increased levels of K carb and K bi-carb. Im trying to hunt down what it could be but i was looking for some input on where to look. It seems like it should really only be from the Carbon or from the Peastone. We rinsed the Peastone of as much residual much and dirt on it. The carbon is still relatively new, with only a few hundred gallons run through it. Will the K levels come down with time as we continue to use the filter, or did we end up with a product that is bad and we need to arrange replacement?
Cheers,
Jeff Marquis
