The operation of thermal devices and installations, in particular heat exchangers, is associated with the formation of various de p osits of sediments, forming the boiler scale. The amount of precipitate depends on the quality of the flowing liquids treatment, as well as the intensity of the use of devices. There are both mechanical and chemical treatment methods to remove these deposits. The chemical methods of boiler scale treatment include the cleaning method consisting in dissolving boiler scale inside heat devices. Worked out descaling concentrate contains phosphoric acid (V) and the components that inhibit corrosion, anti-foam substances, as well as anti-microbial substances as formalin, ammonium chloride, copper sulphate and zinc sulfate. Dissolution of the boiler scale results in the formation of wastewater which can be totally utilized as raw materials in phosphoric fertilizer production. As a result, both the preparation produced and its use are entirely free from waste. (original abstract)
