Moreover, untreated water systems are prone to biological contamination that may lead to the growth of algae, bacteria, and fungi. This biological growth not only decreases system efficiency but can also produce harmful byproducts that affect air quality and pose health risks to personnel.
One of the foundational chemical treatment processes is coagulation and flocculation. In this method, chemicals known as coagulants are added to the water to destabilize suspended particles. Common coagulants include aluminum sulfate (alum) and ferric chloride. These chemicals cause small particles to clump together into larger aggregates, or flocs, which can then be removed from the water through sedimentation or filtration. This process significantly improves water clarity and is often used as a preliminary step in drinking water treatment.
4. pH Adjusters Maintaining the proper pH level in cooling water is crucial for preventing corrosion and scaling. pH adjusters, such as sulfuric acid or sodium hydroxide, are used to regulate acidity or alkalinity, ensuring that the water chemistry remains within an optimal range.
