Objective:
The aim of this project is to assist a small community with a population of less than 10,000 to improve nutrient removal of ammonia, nitrogen, and phosphorus from the wastewater treatment lagoons using innovative technologies. The northwestern Michigan community lies in a humid continental climate, where the mean temperature range is 17.0 to 64.9 degrees F (NOAA 2021) and the average seasonal snowfall is approximately 200 in/yr (Keweenaw County 2021); representing climate extremes found across the U.S. The pilot sustainable floating treatment wetland (FTW) and monitoring system to be developed and demonstrated here at a low cost will be transferable to similar climates and communities across the U.S.
Progress Summary:
The first project year gathered baseline data on the performance of the wastewater lagoons prior to installation of the FTWs. Baseline data gathered in year 1 includes nutrient data, hyperspectral lightweight portable radiometer (LPR) data, hourly lagoon photos, test hyperspectral images, microbial community composition data. A Biowin model of the existing lagoon system was developed. An educational model on data cleaning was developed.
Future Activities:
Selected wetland plants will be installed in the Beemats floating system in the 2024 field season, with plant harvesting and analysis for nutrient uptake in the fall. The next reporting period will include a BioWin model that incorporates the FTW and is calibrated with data following the FTW installation. We will quantify the photochemically produced reactive intermediates and fate of reactive nitrogen species. Life Cycle Cost and Environmental Assessments will be developed.
