Description

Our research is evaluating how sustainable and practical duckweed is as a treatment option for removing phosphorus from wastewater lagoons which ultimately improves the water quality of streams and reservoirs downstream. Duckweed grows naturally in many climates including northern Utah and requires phosphorus to sustain its fast growth rate. After duckweed uptakes phosphorus from the wastewater and into its biomass, the harvested biomass may then be converted into methane or used as an animal feed. Our research is measuring duckweed growth rates in the lab and field, phosphorus removal rates, methane production by anaerobic digestion of duckweed, and potential to use duckweed as an animal feed. Advantages and disadvantages of each option are discussed in this presentation.
