How Does It Work in Swimming Pools?

Have you ever heard about ozone generators? Do you know how do they work in swimming pools? Or, you maybe want to know how does ozone work in pools and what factors affect its work in a swimming pool. In order to find out the answer to all these questions, keep on reading the following lines.

The ozone generator acts as a sanitizer or an algaecide that protects swimmers against bacteria, viruses and infections. However, it is not as dangerous as chlorine or other sanitizers that contain harmful chemicals. It is more like a chlorine alternative. There are so many alternatives on the market, that it is quite difficult to find the right one, but most people opt for this method as it is the safest of all. These systems work with ozone.

They release this unstable molecule into the water in order to stabilize a normal pH level. However, keep in mind that ozone only works if a few factors are met. For example, the outside temperature is an important factor that can change the good work of the generator. In addition to this, something else will determine how effective this method is: The size of the pool. Take a real measure of your swimming pool and choose a unit that is suitable for it. These types of generators, especially the latest versions use ultraviolet (UV) lights from the sun to create ozone. The newest models are equipped with improved technologies, so although they are a bit more expensive, the investment is justified.
