Duckweed (Lemna minor L.) – an experimental plant for phytoremediation of dairy effluent

The small and medium dairy factories generate effluents that represent a significant environmental impact, especially when they are located near ecologically sensitive areas. From an environmental point of view, dairy effluents pose a considerable risk of eutrophication in slow moving receiving waters. Dairy effluents exhibit high COD and BOD values due to lactose and fat contents, leading to a high consumption of dissolved oxygen in water. Furthermore, the high values of ammonium nitrogen (NH4+-N) can have toxic effects on aquatic life. Such effluents may significantly burden the local municipal sewage treatment systems with organic matter.Study indicated phytoremediation ability of Lemna minor L. for treatment of cheese whey wastewater.
