Major sewage discharges can be treated by conventional systems but routing small rural
areas to large treatment works can be expensive. Discharge of organic and inorganic …

The paper reviews the published literature on the studies of competition and allelopathy in
aquatic plant communities. Taking a broader view of the community, the studies on …

Spirodela oligorrhiza, a promising duckweed identified in previous studies, was examined
under different cropping conditions for nutrient recovery from swine wastewater and biomass …

Mathematical models of the growth of water hyacinth are developed to provide a sound
basis for assessing existing and potential control options. We show that under constant …

Nitrogen transformations in wetland ecosystems are very complex. The processes that affect
the removal and retention of nitrogen during wastewater treatment in constructed wetlands …

The operation of six duckweed treatment systems is briefly reviewed. Significant design
considerations include a 20-day detention time for algae removal in wastewater lagoons, a …

The effect of nitrogen (N) levels of the culture medium (0.5–50.5 mg N l− 1 or 38–3820 mg N
m− 2 day− 1) on net productivity and nutrient (N, phosphorus (P) and potassium (K)) storage …

Seasonal growth characteristics and biomass yield potential of 3 floating aquatic
macrophytes cultured in nutrient nonlimiting conditions were evaluated in central Florida's …

Seasonal growth characteristics and biomass yield potential of 4 small-leaf, floating, aquatic
macrophytes cultured in nutrient nonlimiting conditions were evaluated for central Florida's …

A comprehensive model based on a new approach was developed to simulate the
duckweed growth under controlled conditions. Contrary to other approaches which use the …
