3. pH Adjusters (e.g., Lime and Sodium Bisulfite) Maintaining the correct pH level in water is essential for optimal chemical reactions and overall water quality. pH adjusters provided by suppliers help balance acidity and alkalinity, enhancing treatment processes.


Sodium thiocyanate is widely used in various industrial processes. In the textile industry, it serves as a chemical agent in the dyeing process, particularly for producing vibrant colors in fabrics. The compound's ability to facilitate the reaction between dye and fabric ensures a more consistent and long-lasting color. Furthermore, sodium thiocyanate is utilized in the extraction of precious metals such as gold and silver. Its complexation ability allows for better recovery rates, making it a critical component in metal recovery processes.


One of the most critical aspects of water treatment is disinfection. Chemicals such as chlorine, chloramines, and ozone are commonly used to kill bacteria, viruses, and other harmful microorganisms that can pose health risks. Chlorine is the most widely used disinfectant due to its effectiveness and cost-efficiency. However, treatment facilities must carefully manage chlorine levels to minimize the formation of disinfection byproducts, which can have adverse health effects.
