The pH level of water can significantly impact its chemistry and usability. In many cases, it is necessary to adjust the pH to neutral levels for optimal treatment and safety. Chemicals like sulfuric acid or sodium hydroxide are commonly used for this purpose. By balancing the pH, water becomes less corrosive and more effective for disinfection processes. This adjustment also helps in preventing the leaching of heavy metals from distribution pipes, thereby protecting water quality.


 

Despite its utility, handling sulphamic acid requires caution. It can be corrosive and irritant to the skin, eyes, and respiratory tract. Inhalation of its dust or mists can lead to respiratory issues, and contact with skin can cause burns. Therefore, individuals working with this compound must adhere to strict safety protocols, including the use of proper personal protective equipment (PPE) such as gloves, goggles, and respirators.


 

Corrosion is another major issue in chilled water systems that can lead to equipment damage and unscheduled downtime. The presence of dissolved oxygen, carbon dioxide, and chlorides can exacerbate corrosion processes. To mitigate this risk, corrosion inhibitors, such as nitrites, phosphates, or azoles, are added to the chilled water. These inhibitors form a protective film on the metal surfaces, effectively shielding them from corrosive agents. Implementing a tailored chemical treatment program not only prevents corrosion but can also extend the lifespan of the system components.
