Project description
Wetland plants have long been recognised for their role in wastewater treatment, as they have the ability to take up or remove nutrients from the surrounding environment and incorporate it into their tissues at concentrations higher than the environment. The project aims at monitoring the removal rates of nutrients in winery wastewater by macrophytes and comparing them to the effluent compositions and testing the behaviour of macrophytes towards COD and Na loading.
Objectives: Determine the tolerance range of some macrophytes to various concentrations of sodium in combination with COD. Determine and compare nutrient and heavy metal concentrations in the different macrophyte tissues. Study the removal efficiencies of pollutants and other nutrients by the different plant species. Determine the vegetative response to sodium loading and COD concentrations.
