Westernport Water has joined forces with scientists to explore how floating wetlands can be used in the wastewater treatment process.
The two-year research project from 2023-2025 involved the installation of a floating wetlands system on a wastewater lagoon at Cowes Wastewater Treatment Plant.
Floating wetlands are a recent innovation for wastewater treatment. They mimic the appearance of a natural floating island. Like a hydroponic system, the roots of native plants grow into the water under modules that float on the surface of the water.
As the plants grow, their roots provide habitat for microorganisms that assist with the removal of wastewater pollutants and capture floating particles in the water.
Together with scientists from Deakin University and CSIRO, Westernport Water are monitoring the plants over two-years to evaluate their impact on nutrient removal and greenhouse gas reduction. The removal of emerging contaminants to the plant tissue is also being investigated.
