Tests!
The NanoCarb Advanced Wide-Spectrum Carbonit Monobloc Water Filter has been continuously tested
in independent laboratories located around the world.
The information
provided herein is only but a portion or summary of test results. We will
increase test results in this section as time progresses in order to provide
current and potential users with an easy method of determination of the
filtration capabilities and usefulness of NanoCarb products and technology
for your applications.
1)
Typical laboratory and trial results with NanoCarb?
A)
Six month Polio Virus and Anthrax (replacement spores) study under real
usage conditions showed no passage of Polio Virus and Anthrax during the
complete test period which stopped when filters were totally and mechanically
blocked or saturated (clogged).
B)
Study of the removal of pharmaceutical residues, steroid hormones and polar
pesticides from fortified drinking water samples with NanoCarb drinking water filters, until filters were mechanically blocked (filter lifetime).
The
following compounds were tested in this study:
-
carbamazepine
(antiepileptic drug), clofibric acid (active metabolite of several blood
lipid regulating drugs), diclofenac (analgesic, antifheumatic drug), ibuprofen
(analgesic antifheumatic drug), ketoprofen (analgesic drug) and propyphenazone
(analgesic drug).
-
17B-estradiol
and ethinyl estradiol as environmentally relevant steroid hormones.
-
the
polar herbicides mecoprop, dichlorprop, MCPA, 2,4-D, bentazone and the
pesticide metabolite p,p6-DDA (polar metabolite of the insecticide
p,p9-DDT).
Test
results thoughout the testing period showed removal effeciencies greater
than 99,5% to 99,9%
C)
Study of copper removal with feed water containing 3,4 mg/l to 4,5 mg/l
was conducted until filters were saturated. Passage of copper at the beginning
of the test was 0,02 mg/l and by the end of the tests at 0,43 mg/l. Hence
removal was 99% at the beginning of tests and 90% at the end of tests.
D)
Six month study on two bacteria loaded feed water samples, with analysis
every two weeks. Water was drawn from the filters every 3 days to simulate
low usage, hence enabling bacteria to have enough time to grow and proliferate.
The table below shows the results.
