Disinfection is a process which destroys or irreversibly inactivates micro-organisms, reducing their numbers to a safe level.
Its purpose is to leave a clean water supply. It must be carried out in the following circumstances:
- During routine annual system maintenance
- New installations n After major system extensions or alterations
- After installing underground pipework, except localised repairs which require prior disinfection of components
- Where it is suspected that contamination may have occurred: i.e. fouling by sewage, or if systems have been inspected or repaired
- Where a system has not been in regular use nor regularly flushed
What should be done?
Fernox offers a silver catalysed hydrogen peroxide treatment, Fernox LP Sterox.
Fernox LP Sterox
This product treats a wide spectrum of biocidal activity including all water-borne bacteria and viruses. It is particularly valuable in modern water system hygiene management where more conventional treatments such as chlorination are unsuitable. Fernox LP Sterox is supplied in one litre bottles. This will treat 300 litres of system water. After treatment, it is not critical that Fernox LP Sterox is flushed from the water supply as it naturally decomposes to water and oxygen.
Water should be run from each outlet and tested with a Fernox LP Sterox Test Strip until the concentration in the water is less than 200ppm.
