Laboratory 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.
