Concentrations of NH 4 +-N and PO 4 -3-P and their uptake efficiency from 10% anaerobically digested swine wastewater (ADSW) by duckweed and azolla. (A) Initial concentrations of NH4+-N and PO4-3-P in 10% ADSW. Nutrient concentrations and their uptake efficiency by: (B) duckweed at day 10; (C) duckweed at day15; (D) fresh duckweed at day 15; (E) fresh azolla at day 15.
