MSU Vertical Flow Wetland Pilot Update: Optimising Treatment Under Challenging Conditions

The MSU vertical flow wetland pilot in the USA treated high-strength wastewater, focusing on optimising operational parameters for chemical oxygen demand (COD) and total nitrogen (TN) removal. The system demonstrated effective denitrification and nitrification across different stages, ensuring compliance with treatment performance standards. Additionally, the pilot monitored greenhouse gas (GHG) emissions, providing valuable data on the environmental impact of the treatment process.

Challenges included the short operational window of the ski resort that feeds the system and adverse conditions requiring snow removal during sampling events. Despite these difficulties, the pilot successfully optimised treatment processes and provided insights into managing high-strength wastewater under challenging conditions.

The findings from the MSU vertical flow wetland pilot contribute to the broader understanding of wastewater treatment optimisation and environmental monitoring. The data collected on GHG emissions and treatment performance can inform future implementations of similar systems, highlighting the importance of adapting to local conditions and operational constraints.
