Aluminum Sulfate (Alum) Industrial Coagulant
What is Aluminum Sulfate (Alum)?
Aluminum sulfate is a mineral salt whose most important characteristic is its ability to act as a coagulant and flocculant. When this substance is added to water, the positively charged aluminum ions neutralize suspended colloidal particles (such as silt, bacteria, and impurities) which carry a negative charge.
This process causes the fine particles to stick together, forming larger and heavier flocs that can be easily settled or filtered out. This property has made alum the backbone of water and wastewater treatment processes.
