EPA Sampling and Analysis Methods

How much copper can your media sorb within 20 seconds
@ 232.2 gph out of tap water?

How much chelated Copper can your media sorb in 14 minutes and
16 seconds from synthetic seawater @ 232.2 gph (3.87 gpm)? EPA Method 7210

Did you know that adding calcium supplements puts additional lead into your marine or reef tank? How much of this added lead (Pb) can your filter media remove from synthetic seawater? EPA Method 7421

Does your carbon media really adsorb volatile organic chemicals? Did you know that chloroform (CHCI3) is used as a surrogate for volatile organics? How much chloroform can your carbon adsorb from water? EPA Method 502.1

EPA Method 7210
Poly-Filter sorbed 47.96% of 718.95ng/ml copper out of tap water, producing 374.09 ng/ml filtrate! (2) PMA 12/Pks sorbed 46.4% of 1570.16 ng/ml chelated Cu (CopperSafe) to produce 841.86 ng/ml filtrate @232.2 gph.

EPA Method 7421
Our standard Poly-Filter cut into discs (2.75" dia.) sorbed 63.47% of 248.38 ng/ml (lead) producing 90.72 ng/ml filtrate after 14 minutes and 16 seconds @ 232.2 gph flow rate. 8.12pH-8.39pH.

EPA Method 502.1
Our PMA 12/Pk sorbed 73.85% of 347.01 ng/ml chloroform (CHCI3) to produce a 90.71ng/ml chloroform filtrate. We produced potable water on a single pass! We know our data is more usable than pore sizes and volume ratings.

Note: ng/ml = µg/l
µg/l = part-per-billion
