Growth and kinetic studies on tropical aquatic plants in the presence of macro-nutrient (nitrate) accumulation.

High levels of nitrate in reservoirs and waterways make the water unsafe for consumption. In addition, the water can become eutrophic, causing it to become unattractive and threatening the aquatic ecology. Wastewater treatment systems which are currently available could generate undesirable by-produ...
