Scaling is another common issue faced by cooling towers, primarily caused by the precipitation of minerals from the water during the cooling process. Scale can build up on heat exchange surfaces, diminishing thermal efficiency and leading to operational failures. To combat this, scale inhibitors are used to prevent the precipitation of hardness minerals like calcium and magnesium. Products based on phosphonates and polyacrylic acids are often employed to disrupt crystal formation and maintain a clean heat exchanger surface, ensuring optimal heat transfer efficiency.


Historically, ammonium mercuric thiocyanate played a crucial role in identifying and isolating thiocyanate ions in analytical chemistry. It was typically used in qualitative tests to detect the presence of thiocyanate, a process that has paved the way for broader applications in chemical analysis. Its use, however, has decreased over the years due to the growing concerns over mercury toxicity and the move towards safer, more sustainable alternatives.
