we are offering superior water conditioner, cooling water from a lake or river typically contains a few hundred ppm of anions and cations, most notably calcium, sodium, magnesium, potassium, bicarbonate, chloride, silica and sulphate, as well as other materials, including suspended solids. in cooling towers, these impurities cycle up in concentration. as these contaminants enter the boiler, a number of temperature induced reactions occur. two common reactions are shown;  ca2+ + + 2hco3 == caco3 + co2 + h2o  ca2+ + (or mg2+) + sio32- = casio3 + (or mgsio3) these are scale formation reactions that superior water conditioners will prevent from occurring. these reactions causing a thin deposit on the internals of pipes will significantly reduce heat transfer and a boiler must be fired harder to achieve the same level of steam production. this also can lead to overheating of the boiler tubes which will shorten boiler tube life. much more frightening is the effect that cooling water in-leakage has with regard to rapid and catastrophic corrosion. the reaction shown below is a prime example:- mg2cl + h2o + heat = mg2 (oh)2 + hcl magnesium salts react with water to produce magnesium hydroxide precipitate plus hydrochloric acid. while hydrochloric acid may cause general corrosion in and of itself, the compound will concentrate under deposits where the reaction of acid with iron generates hydrogen which can lead to hydrogen damage of the boiler tubes. in this mechanism hydrogen gas molecules which are very small penetrate into the metal wall and react with carbon atoms in the steel to generate methane (ch4). this non chemical method to control lime scale is not only used to increase quality in the product and reduce production costs but also as a means to reduce pollution and enhance the image of the industry.
