What is the primary role of copper sulfate in water treatment?

Copper sulfate is primarily used in water treatment for algae control. The effectiveness of copper sulfate as an algaecide stems from its ability to disrupt the metabolic processes of algae, ultimately leading to their death. This is particularly important in maintaining clean and safe water sources, as excessive algae growth can lead to problems such as taste and odor issues, as well as water quality deterioration.

In aquatic environments, especially in ponds and lakes, the overgrowth of algae can create oxygen depletion during decay, which harms aquatic life. By applying copper sulfate strategically, water treatment professionals can manage algae populations, thereby promoting a healthier ecosystem and improving the quality of the water supplied for consumption or recreational use.

While copper sulfate may have roles in other applications, its primary function in the context of water treatment specifically relates to controlling algae and preventing harmful algal blooms.
