Efficiency evaluation of wastewater treatment by three macrophytes using a pilot-constructed wetland system in Ota, Nigeria.

Three aquatic macrophytes were used to treat wastewater using a pilot-constructed wetland (CW) system to determine the most efficient plants for removing contaminants from wastewater. The three macrophytes are water hyacinth (), water lettuce (), and duckweed (). Three 150 L capacity tanks with sand and gravel as substrates were used as the pilot CW for each plant.

Performance assessment of local aquatic macrophytes for domestic wastewater treatment in Nigerian communities: A review.

The concept of treating wastewater before disposal is a global necessity. Recent mechanisms of doing this include the use of Constructed Wetland Systems (CWS). This technique is believed to be cost-effective and simpler compared to conventional methods.
