Xylem helps ensure successful passages by treating drinking water, wastewater and ballast water.
​Our pollution-free ultraviolet (UV) technology combined with filtration is a most effective, environmentally friendly and easy-to-implement system. A sensible alternative to chemical disinfectants and expensive membrane systems, our UV technology greatly improves the health of crew members and protects waterways and their ecological systems.
Some of the ways Xylem helps with maritime water treatment include:
  • Treating drinking water and wastewater: The great advantage of UV light compared with other techniques is the environmentally friendly way in which it works:
    • Viruses, bacteria and parasites are inactivated by a photochemical reaction between the UV radiation and the genetic information carrier (DNA) of the pathogen within seconds
    • The pathogen can no longer multiply and dies; because this is a purely physical technique, the pathogen types do not become resistant to the UV radiation
    • No harmful by-products form in the water
    • The natural taste and odor of the water are preserved


  • Treating “stowaways” in ballast water: In order to prevent organisms, algae and micro-organisms from spreading into other offshore ecological systems, ballast water must be treated before it is released into coastal waters. There are several advantages to treating your ballast water with Xylem’s UV and filtration systems:
    • “Stowaways” are rendered harmless, effectively and completely
    • No chemical additives are put into the water with UV disinfection; the water retains its natural characteristics
    • No toxic by-products form
    • Considerably lower space requirements compared with alternative methods

  • Providing a wide array of UV disinfection products and accessories such as:
    • The effective applications of high-performance, energy-efficient UV lamps that destroy more than 99.99% of all waterborne pathogens — in just seconds
    • UV disinfection for liquids with low UV transmittance
    • Flow-rate up to 1.335 m³/h per unit
    • Available seawater-resistant UV chambers made of marine-graded HDPE (Polyethylene)
