Eco friendly pool sanitation can a ozone system keep our pool clean?

Answer 1

Ozone for pool sanitization is most cost effective (including consumption of electrical power, some of which is still fossil fuel derived) when it is used to "reactivate" the actual sanitizer in the pool. Ozone will reactivate bromine compounds to hypobromous acid, and bromine has a lower vapor pressure than chlorine, so you can use less bromine if you add ozone, than you would ever be able to get away with for chlorine (because ozone and chlorine are not synergistic in the same way... or at all). This means less hardness change due to chemical additions... more chemical savings. There are pools that use ozone for the primary (pre-filter) and secondary (in the pool itself) sterilant. They are made from special materials (especially the pumping / filtration), take special pool coatings (regular paints fail quickly), and take a much more expensive ozone generator (both to buy and operate). Most eco-friendly of all, is not to have a private pool, but to use a community pool instead. It is safer than most public bodies of water... if the pool is well maintained.
