Understanding Water Filtration – Part 2

Now that we identified the different types of filtration technology let’s discuss particle sizes a bit. Depending on the type of contaminant and the type of filtration we are using, science uses three main conventions to describe particle size. Micrometers or microns – 1 micron = 0.00004 inches Angstrom units – 1 angstrom = 10(-4) microns. Or 10,000 angstroms = 1 micron Molecular Weight Units – 0 – 500,000. The…
