Ozone disinfection
The Illustrated Guide to Hot and Cold Water Services (BG 33/2014), written by Reginald Brown and published by BSRIA in 2014. In relation to ozone disinfection, it states: ‘Ozone Ozone (O3) is formed by an ozone generator that exposes oxygen to a high voltage electric field. Ozone is a highly effective oxidising biocide with limited persistence and quickly reverts to oxygen without formation of harmful by-products. Care is needed in the choice of the materials near the injection point as trace levels of ozone will react with a wide range of materials including rubber that may be present in water fitting seals. Ozone is widely used for water treatment at the utility scale. Small units are readily available for industrial process use but it is not clear how cost-effective they might be for building applications compared to other possible disinfection methods.’
