Drinking Water Treatment

 

  • Purpose

    Water purification removes contaminants like bacteria, algae, viruses, and fungi to provide clean drinking water. It also meets the needs of other industries and applications for clean water..
  • Disinfection

    Disinfection is important for providing safe drinking water and is often done with chlorine.
  • Contaminants

    Water treatment removes contaminants that are harmful to health and those that make the water smell, taste, or look bad.
  • Objectives

    The main objectives of water treatment are to:

    • Reduce or remove contaminants
    • Raise water quality
    • Meet water quality standards
    • Reduce waterborne diseases

    Reverse Osmosis Systems

    • Reverse Osmosis Systems use a process that reverses the flow of water in a natural process of osmosis so that water passes from a more concentrated solution to a more dilute solution through a semi-permeable membrane. Pre- and post-filters are often incorporated along with the reverse osmosis membrane itself.
    • A reverse osmosis filter has a pore size of approximately 0.0001 micron.
    • Reverse Osmosis Systems have a very high effectiveness in removing protozoa (for example, Cryptosporidium, Giardia);
    • Reverse Osmosis Systems have a very high effectiveness in removing bacteria (for example, Campylobacter, Salmonella, Shigella, E. coli);
    • Reverse Osmosis Systems have a very high effectiveness in removing viruses (for example, Enteric, Hepatitis A, Norovirus, Rotavirus);
    • Reverse Osmosis Systems will remove common chemical contaminants (metal ions, aqueous salts), including sodium, chloride, copper, chromium, and lead; may reduce arsenic, fluoride, radium, sulfate, calcium, magnesium, potassium, nitrate, and phosphorous.

    Hygiene

    In addition to providing safe drinking water to your household, you can also protect yourself and others from waterborne illness by paying practicing good personal hygiene.
