There is a lot of controversy being spread on the internet about UV versus corona discharge to generate ozone gas. What is the truth? Well proponents of UV ozone claim that it is the only way to generate pure ozone gas. While it is true that UV ozone generation can be pure if you feed pure oxygen into any corona discharge machine you will get pure ozone. What the UV guys won’t tell you is that the UV method will never produce massive amount of ozone gas. They will never produce kind of gas necessary, in the quantities necessary, to perform SHOCK OZONE TREATMENTS. Let’s face it when you are performing a SHOCK TREATMENT you need massive amounts of gas, and corona discharge is the only method capable of generating that kind of volume it's what professional contractors rely on and so should you!(Source: http://en.wikipedia.org/wiki/High-ozone_shock_treatmenthttp://www.waterth.com/products/pdf_files/applier_ozone.pdf)
