Several factors separate RO systems from some of the more conventional approaches. The capacity to reduce and eliminate contaminants, however, is what’s at the crux of the matter. We need to take a closer look at the types of contaminants that a traditional filtration method removes versus that of an RO system.
Here is what conventional filtration can remove:
- Volatile Organic Compounds. This typically involves industrial solvents, fuels, and radioactive materials.
- Herbicides, pesticides, and other substances that are used for pest control.
- Disinfectants (such as chlorine) typically used in water treatment facilities.
- Awful odors and bad taste.
An RO system will remove everything mentioned above plus:
- Salts, nitrates, and heavy metals such as lead or copper.
- Hard minerals that form deposits on metallic surfaces, including magnesium and calcium.
- Organic chemicals such as fluoride.
- Viruses and harmful bacteria. Some examples include E. Coli, Hepatitis, and Salmonella.
- Arsenic and other toxins
RO systems aren’t as effective as an activated carbon filter at removing VOCs and other organic compounds, but there is no denying that they are extremely serviceable.
