Abstract

Wastewater is any liquid or water-carried waste accrued from sanitary operations. This waste contains toxins that must be purified, as they pose an environmental and public health hazard. Specifically, this risk is high in developing countries. Aquatic plants can be used to purify wastewater. Duckweed is a free-floating aquatic plant with over 37 species, but Lemna minor is typically used for wastewater management. This research focuses on finding different species to use in wastewater management. Spirodela polyrhiza and Lemna minuta chlorophyll concentration and frond increase were compared with Lemna minor. The species were maintained in varying concentrations of Hoagland’s solution for a range of weeks before they were harvested. Results show Lemna minor is the preferred species of duckweed for wastewater management.
