Eau Potable
Ozone production technology is in most cases the only method that effectively allows for the production of high-quality drinking water. The R.P. OZONE inc. method using ozone is essentially used for the following purposes:
- disinfection, aka the destruction of micro-organisms (giradia lamblia/inactivation of viruses / elimination of cryptosporidium)
- elimination of odours (deodorisation)
- elimination of humic substances (decolouration)
- improvement of taste
- oxidation of iron and manganese
- degradation of pesticides
The advantages of ozone versus chlorine are the following:
- no production of haloformes
- small amount of ozone is required, which reduces the investment and operating costs
- no by-products
- does not affect pH level
- support and partial replacement of flocculants
The treatment of drinking water with ozone has two phases, decolouration, oxidation of iron and manganese, disinfection and deodorisation take place during pre-ozonation (and eventually inter-ozonation). As a general rule, the principal ozonation phase is used to degrade organic matter and eliminate cryptosporidium, giradia, etc.

These guidelines are from taken from Quebec’s provincial guidelines on drinking water (Règlement sur l'eau potable du Québec) and recommendations for drinking water quality established by Health Canada.
