How can seasonal algae blooms affect water treatment processes?

Seasonal algae blooms can significantly impact water treatment processes, mainly due to the increase in organic material they contribute to the water supply. When algae bloom, they produce a high biomass that can lead to elevated levels of organic compounds, including natural organic matter (NOM). This increased organic load can create challenges during the treatment process.

The presence of excessive organic material necessitates additional treatment measures to ensure water quality standards are met and to effectively remove potentially harmful byproducts. For example, conventional treatment processes like coagulation, sedimentation, and filtration may require optimization or adjustment to address the larger volume of organic matter. Without appropriate treatment adaptations, this increase can hinder the effectiveness of these processes and lead to issues such as taste, odor, or even unsafe drinking water levels.

In contrast, other outcomes like decreased disinfection needs or claims of no significant impact on treatment processes ignore the complexities introduced by algal blooms. Similarly, while algae blooms can reduce the efficiency of filtration systems, the primary concern revolves around the overall increase in organic material necessitating enhanced treatment responses.
