What are volatile organic compounds (VOCs) and why are they significant in wastewater treatment?

Volatile organic compounds (VOCs) are characterized as organic chemicals that can easily evaporate at room temperature. This property makes them significant in the context of wastewater treatment for several reasons. Primarily, VOCs can contribute to air pollution when they evaporate and enter the atmosphere, leading to the formation of ground-level ozone and smog. Their presence in wastewater can indicate contamination from various industrial processes and activities, making it essential to monitor and treat them effectively to protect environmental and human health.

Treatment methods in wastewater plants may need to specifically address VOCs to reduce their concentrations before discharge into the environment, as they can pose risks to both water quality and air quality. Monitoring levels of VOCs in wastewater can also be crucial for regulatory compliance, ensuring that treatment facilities meet environmental standards and protect public health.
