Method for the control of corrosion and bacteria from Legionella family in hot service water installations and cooling systems

摘要

the invention discloses a way of combating corrosion and bacteria from the family of legionella in water heaters and galvanised installations in cooling systems. how is the initial cleaning chemical installations, using the known chemical bath and then introduction to the chemical compositions.introduced the chemical composition gives rise to an aqueous solution containing: 1 0001 weights. sodium hydrogen carbonate or potassium, 0.7 to 0001% by weight. sodium carbonate or potassium, 0.5 to 0.002 wt%. pyrophosphate sodium or potassium, 0.5 to 0.002 wt%.polifosforanu sodium of formula (napo3) n, where n is a positive integer value in the range 6 to 22, 0.6 to 0001% by weight. the sodium or potassium salts, methyl ester of p - hydroksybezoesowego and 0,5 to 00001% by weight. guanidine hydrochloride or phosphate derivatives.
