Part 1 & 2 The Microscopic Monster | Christine Wood, PE

Tuesday, June 14, 2022 at 1:30 pm

This presentation focuses on microplastics in wastewater and their impact on the treatment process. Microplastics are ubiquitous in the environment and are found in the influent wastewater stream. Current regulations do not require treatment plants to monitor the flow of microplastics through the plant; however, they are a growing health concern and WWTPs are considered a point source for the release of microplastics to the environment. Conventional wastewater treatment processes remove approximately 90% of influent microplastics with additional removal provided by tertiary treatment.
