Application

LP Sterox Test Strips come in a pack of 50 strips and are designed to give a quick and clear indication of adequate dosing of LP Sterox in a system. Once the system is dosed with LP Sterox, the furthest tap from the tank or dose point should be run out to allow the LP Sterox to move through the system prior to testing. Dip a test strip into a sample of system water for two seconds, wait 10 seconds and then compare to the colour chart on the side of the container. 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. Should the test strip show the required concentration of LP Sterox is not adequate, dose the system with the required amount of LP Sterox required to achieve the 100ppm in-use concentration of hydrogen peroxide and retest following the above procedure. For further information on treating legionella, consult BS EN 8580, ACoP L8, HSG274 and HSG282.

Frequently Asked Questions

How to avoid bacterial contamination?

Algae in feed and expansion cisterns Leathery skins or films of algae on the surface of expansion cisterns in open vented systems are caused by fungal mould growths. It occurs when the expansion cistern is not properly covered causing dust, insects and spores to be able to enter the water.Algae in feed and expansion cisternsUnderfloor heating systems are also susceptible to microbial growth due to the lower temperatures at which these systems operate.Gas in the system Microbiological fermentation in a system could result in flammable gas. Methane gas, which burns with a blue flame, is most often found.Hydrogen sulphide (emitting a ‚Äòbad egg‚Äô smell) may also occur, and is associated with the presence of corrosive sulphate-reducing bacteria.Bacterial or yeast infestations caused by organisms entering the system from the supply water; debris in new systems or through air contact in open expansion cisterns can also occur.What should be done?To combat algae in open vented systems, empty the cistern and disinfect with Fernox AF-10 Biocide or Fernox LP Sterox. Refill the tank, adding the correct dose of AF-10 Biocide (refer to the instructions on the container)and top up the concentration levels of Protector F1. Ensure the tank is fitted with a purpose-made lid to prevent future contamination of the tank.When there is gas in a system,use Fernox AF-10 Biocide to control microbiological growths and prevent gas build-up. Where contamination is significant,several repeat doses of biocide may be required: in such situations, it may be appropriate to drain and retreat the entire system.Bacterial contamination in air and ground source heat pumpsWhen there is bacterial contamination in air and ground source heat pumps, Fernox HPCleaner can be used.Before use, it should be diluted using no more than 600 litres ofmains water per one litre of HPCleaner (equivalent to 600 metres of 40mm pipework). The ground collector must be flushed out with fresh mains water before being filled with the diluted product.Having circulated the HP Cleaner for at least one hour, after whichit should be flushed out until thewater runs clear. Fill the ground collector with Fernox HP-5 /HP-5c or HP-15 / HP-15c depending on the level of frost protection required.
