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.

To address these concerns, many plants have turned to alternative disinfectants like ozone and ultraviolet (UV) light. Ozone is a powerful oxidant that can inactivate a wide range of pathogens and is particularly advantageous because it leaves no residual chemicals in the treated water. UV disinfection, on the other hand, uses ultraviolet light to disrupt the DNA of microorganisms, effectively neutralizing them without adding any chemicals.

Chemical treatment processes involve the addition of chemicals to water or wastewater to facilitate the removal of contaminants. One of the most widely used chemical treatments is chlorination, which involves adding chlorine or chlorine-based compounds to disinfect water by killing pathogens. However, this method must be carefully managed, as excessive chlorine can lead to the formation of harmful by-products.
