UV & Silver Ion Water Sterilization
FAQ's
What does a UV water sterilizer do on a boat?
A UV water sterilizer eliminates bacteria, viruses, and microorganisms from onboard water by exposing it to ultraviolet light as it flows through the unit. It adds nothing to the water and requires no chemicals — making it the safest and most effective method of biological sterilization for marine use.
What is the difference between UV sterilization and silver ion water treatment?
UV sterilization provides instant elimination of bacteria and viruses at the point of use as water flows through the unit. Silver ion treatment provides continuous antimicrobial protection throughout tanks and pipework between uses. The two technologies are complementary and work best together as part of a complete onboard water system.
Do I need a UV sterilizer if I already have a watermaker?
Yes. A watermaker produces clean water but does not sterilize it. Once water enters your tanks and plumbing it can become contaminated through tank vents, hose connections, or biofilm in pipework. A UV sterilizer installed before the tap ensures water is biologically safe at the point of consumption.
Is there a 12V UV sterilizer for sailboats?
Yes. The Revive Water UV Light Filter Kit 12W is available in 12V DC and 24V DC configurations — suited to sailboats, solar-equipped cruisers, and any vessel where AC power is not available at the sterilization point.
What is the JOWA silver ion sterilizer used for?
The JOWA Ag-S Silver Ion Sterilizer doses controlled silver ions into the freshwater distribution system of larger vessels and superyachts — providing continuous antimicrobial protection throughout tanks, pipework, and hot water systems without chemicals.
