Steritank HP is an effective and environmentally friendly liquid disinfectant suitable for potable water, based on stabilised Hydrogen Peroxide. Unlike chlorine it has no taste or odour of its own so it is ideal for the disinfection of drinking water tanks and piping and other applications in horticulture and bottling. It is suitable for one-off or continuous disinfection or deodourisation of the water in a tank. Steritank HP can be added directly to the tank and mixed in. Electricity is not required.
