The #1 Way to Keep Your RO Bacteria-Free

“Keeping bacteria under control in a reverse osmosis is impossible.”

That’s what most water treatment professionals seem to believe. What they don’t know is that there’s a solution that exists and works really well but that hasn’t really made its way into the mainstream for protecting RO yet.

Why should you care? Well, perhaps you:

  • Clean your membranes frequently because of organic fouling (like twice a year or more)
  • Need to maintain low TOC or bacteria concentrations in your pure water
  • Want to optimize your RO’s efficiency and prevent downtime

Introducing Chlorine Dioxide

Chlorine dioxide is NOT chlorine. It doesn’t damage RO membranes. It remains in gaseous form in water and successfully penetrates biofilm and passes through RO membranes, meaning it prevents bacterial growth on the “pure water” side of membranes.

ClO2 is used by many industries for other applications like bleaching, manganese reduction and potable water disinfection.

Isn’t Chlorine Dioxide Dangerous to Produce?

Chlorine dioxide generation has been a real challenge until fairly recently. You see, making chlorine dioxide requires that it be produced at relatively high concentrations. At these high concentrations it’s prone to off-gassing and is highly explosive once it’s in air at high enough concentrations. There have been numerous explosions caused by chlorine dioxide generators in the last century.

Thankfully there are chlorine dioxide generators that use a special process to generate the disinfectant gas and then almost immediately dilute it to safe concentrations.

Check out the Securox system by Thetis Environnement if you’re curious about ClO2 for your applications. It’s been approved for use in nuclear power plants in France. That should be enough to convince you it won’t be blowing up any time soon.
