Water, essential for all life, can be a major source of infection and illnesses. Bacteria, algae and other micro-organisms can grow extremely quickly in water. Just like food, water deteriorates.    

When stored on board, water is prone to fouling and bacterial growth. In order to prevent this and keep your water supply, crew and passengers safe, upgrade your water storage and distribution system with drinking water disinfection technologies such as Ultra Violet water disinfection, Copper/Silver ionisation or our Hadex drinking water disinfectant and chlorination. For larger of more complex installations, one water disinfectant technology is often insufficient. Combine drinking water filter systems and technologies for additional water treatment and healthy working conditions, complying with health regulations such as NIPH, MLC etcetera. 

Ultraviolet drinking water disinfection     

  • Proven, chemical-free and sustainable drinking water filter system for killing pathogens
  • Easy to install and maintain
  • Reliable and proven water disinfection for challenging water conditions
  • Combat potentially dangerous pathogens, including Cryptosporidium and Giardia

Copper/Silver ionisation disinfection of water       

  • Disinfection water treatments that are effective in hot as well as cold water
  • Dosing proportionally to water flow
  • Highly effective water disinfection method for complex distribution systems
  • Drinking water filter systems that clean heavily corroded and contaminated piping
  • 100% effective against Legionella
