    Duckweed was grown in outdoor ponds for the purpose of domestic waste-water treatment, recycling of the nutrient and effluent renovation. Growth of the plant was examined at two pond depths and various hydraulic retention times. Temperature stratification in the ponds probably affected ammonia uptake. Dry yield of the duckweed approached 15 g m-2 day-1 with a protein content of about 30% in the short retention-time treatments. Effluent quality was at the secondary level and met criteria for re-use for agricultural irrigation.
