Some people have called DW Liquid ROS “Liquid Ozone”. Now here at DisinfectWater.com we know that there is no such thing as Liquid Ozone, but we do not argue with the basic premise here.
In the water treatment arena, ozone has proven to be very effective, but unfortunately there are some drawbacks with Ozone. Some of these concerns are initial start up costs, danger of the production, the level of technical skills required to run an ozone system to name a few.
DW Liquid ROS is unique in its ability to deliver very similar outcomes of ozone while also addressing these general concerns. To begin, lets look at the similarities between DW Liquid ROS and Ozone.
What is similar:
Oxidation Potential (the ability of the product to effectively remove pathogens):
DW Liquid ROS=270, Ozone=2.07
So although the numbers are close, DW Liquid ROS does have a higher oxidation potential.
Ability to remove taste & oder and remove waterbourne pathogen.
Both DW Liquid ROS and Ozone are very effective at all of these.
What is different?
Form: How easily can these be handled.
DW Liquid ROS is already a liquid so adding it to water for treatment is easily done, all you need is a metering pump to add the right quantity.
Since Ozone is a gas, it is difficult to dissolve and use efficiently.
Solubility: How easily does this dissolve into water.
As a liquid, DW Liquid ROS is 100% soluble in water. Where Ozone has a maximum solubility of approximately 5%.
Handling: How safe is the chosen product to handle.
DW Liquid ROS is listed as a corrosive, just because of the high PH it is shipped at but can be handled using simple protocols like gloves and eye protection. Ozone, if handled incorrectly can be very dangerous and even explosive.
Potential By-Products: By using the product, what problematic concerns could occur.
Dw Liquid ROS does not have any potential by-products while ozone can result in bromate and HAA5s.
Residual Protection: Will the use of the product continue to work after the initial application?
Ozone does not offer any residual effect while DW Liquid ROS, through the use of hydroxyl Radical Ions, offers lasting residual effects which can be tracked using ORP.
Cost: The most glaring difference between ozone and DW Liquid ROS is the Capital and ongoing cost.
To install an ozone generator at a plant is VERY expensive and requires ongoing maintenance and specially trained staff to monitor and run the system. DW Liquid ROS costs approximately $2 per pound and can used at levels of 3.5 ppm or less depending on the quality of the water. All that is required is maintaining the ORP of the raw water at a level of 700 or more.
