Special care should be taken to prevent alum from getting damp because:

Alum, which is commonly used in various industrial and chemical processes, can easily absorb moisture from the air. When it becomes damp, it tends to clump together, forming solid masses. This phenomenon, known as caking, can lead to several operational issues. Primarily, the clumped alum can jam equipment when it flows through feeders, hoppers, or other handling systems, disrupting the smooth operation of the processes that rely on the consistent flow of this chemical.

Maintaining the dryness of alum is critical to ensure proper handling and dosing in processes where precision is key. If alum is allowed to absorb moisture and caked together, it can affect the dosing accuracy and operational efficiency of the equipment, necessitating maintenance and potentially causing downtime. Thus, preventing dampness is crucial for both the safety and efficiency of the operations involving alum.
