Why use ozone water treatment for your well water?

#1: Ozone is a powerful disinfectant:

Ozone water treatment can rapidly disinfect your well water and kill bacteria and viruses, but unlike chlorine does not leave a chemical chlorine residual.

#2: When used with filtration, it removes iron, manganese and sulfur odor:

The oxidizing properties of ozone, when combined with filtration, will eliminate iron, manganese, sulfur and reduce or eliminate tastes and odor problems.

#3: Ozone is automatic and doesn’t require additional chemicals:

Ozone is a gas that is generated by an ozone generator at your site and injected into your water.

#4: Sizing is critical:

Ozone generators need to be sized to fit the application. Ozone generators produce ozone in grams per hour and depends on your well water flow rate and water chemistry.

#5: Decide on ultraviolet (“UV”) light ozone water treatment or corona-discharge type: 

While UV light can produce low levels of ozone, it works best for removing slight odors and should be not used for disinfection.  Corona discharge uses electricity inside a ceramic or glass cell or stainless steel plate chamber to produce ozone. It works better with dry air and there are cartridges that will produce dry air and help the generator produce high levels of ozone.

#6: Inject ozone under pressure for best results:

Ozone can be bubbled into the water in open storage tanks or low-pressure vessels, but most of the ozone does not get transferred into the water.  It is much better to draw in the ozone with a venturi into a contact tank that is under 40 – 50 PSI of pressure for optimum transfer of the ozone into water.

Ozone Systems Are Widely Use for Bottling Water and Water Purification Worldwide

Ozone has been used for over 100 years to treat water for cities, bottling water plants and other commercial and industrial processes.   Home systems have been available for some years and improved in quality and design.

If you have iron, manganese, odor AND bacteria, ozone combined with proper filtration can work great and last for many years.

Ozone water treatment oxidizes iron, manganese, and sulfur in your well water to form insoluble metal oxides or elemental sulfur. These insoluble particles such as rust, are then removed by filtration which is typically activated carbon, manganese dioxide, or other media such as filter sand.

Ozone is much faster at killing bacteria and oxidizing iron and manganese compared to chlorine or peroxide.  One advantage for home use is that ozone is quite unstable and will degrade over a time frame ranging from a few seconds to 30 minutes.

So if ozone water treatment is so great, why doesn’t everyone use it you may ask?

It is quite expensive compared to chlorination.  Ozone water treatment costs a lot more up front compared to aeration, chlorine injection or hydrogen peroxide injection!  That is the primary disadvantage.  Shop our ozone systems.

Ozone for Disinfection

Ozone has a greater ability to disinfect water of bacteria and viruses compared to chlorination. To properly disinfect water with chlorine or ozone there must be enough residual of the chlorine or ozone in mg/L (same as saying parts per million or PPM) in the water, AND enough minutes of contact time for disinfection to occur.

Water chemistry is also very important.  The pH of the water (how acid or alkaline it is) along with the turbidity and other contaminants all play a role in how effective chlorine or ozone will be at disinfecting your well water of bacteria.
