LP Sterox is a highly effective disinfectant for use against Legionella, pseudomonas, bacteria and algae, as well as the removal of biofilm. Ideal for disinfecting stored water systems in all domestic or commercial properties, LP Sterox is easy to use, with no need to flush out or neutralise the system once disinfection is complete. One bottle will disinfect a 300 litre system during normal use, or 400 litres if the system is not used for 24 hours after application.
One bottle of LP Sterox will disinfect a 300 litre system during normal use, or 400 litres if the system is not used for 24 hours after application. It is not recommended to exceed this dosage rate. For drinking water systems, a full flush is recommended after disinfection to remove any dislodged biofilms before consumption.Test strips are available for monitoring hydrogen peroxide as follows: At the recommended dosage rate, 1 litre contains 100 ppm in-use hydrogen peroxide (0.30% LP Sterox in solution) – this is the required dosage rate for legionella control. For further information on treating legionella, consult BS EN 8580, ACoP L8, HSG274 and HSG282.
LP Sterox is supplied in 1 L bottles.
LP Sterox is classified as non-hazardous for human health, but as with all chemicals, keep out of reach of children. In case of contact with eyes or skin, rinse immediately with plenty of water.

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:
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.
