The term "disinfection" refers to the process of destroying or preventing the growth of disease carrying microorganisms like bacteria and cysts. There are several methods that can be used effectively for the disinfection of water, including chlorination, ultraviolet or UV, and ozonation. However, quantum disinfection, which is the most recent advancement in water treatment technology, may very well be the best method of them all.

Compare the Technologies

Quantum Disinfection

This recent innovation in water disinfection was developed using technology utilized in the manufacturing of semiconductors. Quantum disinfection kills bacteria and other microorganisms at the cellular level instantly upon contact by removing the electrons from their cell structure. It is the method of choice by informed consumers because it adds nothing to the water, has no carbon footprint, and kills up to 99.9999% of microorganisms and viruses. This is a physical disinfection water treatment method, and no chemicals are added to your water.


  1. The best technology at destroying bacteria
  2. Low initial cost
  3. No electricity needed
  4. No chemicals added
  5. Low maintenance
  6. No carbon footprint
  7. Delivers maximum performance, even during power outages
  8. Actually destroys the organism



Ultraviolet Disinfection

UV, as it is often called, is also a physical method for the disinfection of water in that no chemicals are added. An ultraviolet light operates at 254 nanometers (nm) and, as water containing microorganisms passes by the UV light, their DNA is altered so that it cannot reproduce. Since these microorganisms cannot replicate, they are essentially dead. As mentioned, UV adds nothing to the water and while it does use power, it generally costs only about $30 a year to operate.


  1. Moderate initial cost
  2. No harmful chemicals added
  3. No disinfection byproducts


  1. Uses electricity
  2. Requires proper contact time
  3. Bulb contains mercury and must be disposed of properly
  4. When the power goes out, your plumbing system can be compromised with bacteria
  5. Controller (ballast) needs periodic replacement


Ozone, molecularly known as O3, is an outstanding sanitizer and is relentless in attacking organic microbes, such as bacteria, viruses, and cysts, like Giardia and Cryptosporidium. Through a process called "lysing," ozone breaks down cell walls or membranes, allowing it to then destroy the nucleus of the microbe. In addition to sanitation, ozone is well known for its ability to oxidize inorganic materials that could be present in water, including iron, sulfur, and manganese. Although there are a few stronger oxidizers, ozone is the strongest that is readily available for commercial or residential use for disinfecting water. In fact, it is 1.5 times stronger than chlorine and many, many times faster acting.


  1. Outstanding at destroying bacteria
  2. Also oxidizes other inorganic materials
  3. Very little operational costs, except electricity


  1. High initial cost
  2. Requires some contact time
  3. Uses electricity
  4. Ozone must be destroyed after use


The disinfection water treatment of choice for many years, chlorine is starting to decline in popularity due to newer, better, and more economical methods. Chlorine and chloramine (a related chemical) are still the methods of choice for disinfecting water in most municipalities, but homeowners are often hesitant to use chlorination due to the sheer size of the system, the dangerous disinfection byproducts (such as trihalomethane) produced by chlorination, and the service required to keep the system operational. That said, sometimes chlorination is necessary, especially in surface water systems where the presence of algae needs to be addressed.


  1. Chemical disinfection is effective at killing bacteria
  2. Can measure the amount in the water
  3. Effective at killing algae


  1. Requires 20 to 30 minutes of contact time, so a large retention tank is needed
  2. Troublesome technology in that chlorine tends to crystallize and plug at the injection point
  3. Produces disinfection byproducts that are carcinogenic
  4. Corrosive to metals close to chlorine
