Abstract

Water is vital for humans and other living things, but water pollution has become a significant issue today. Various anthropogenic agricultural, industrial, and home activities produce multiple organic and inorganic substances dissolved or suspended in water. The goal of wastewater treatment is thus twofold: to reduce water pollution while also maintaining the water supply to demand. In a 15-day controlled laboratory experiment, Azolla pinnata was used to biotreat wastewater collected from Bahr Hadous, Egypt. It was tested on three levels of wastewater and tap water as a control treatment (5, 10, and 20 cm). The current study aimed to evaluate the ability of Azolla to treat wastewater at different depths. The results of the study showed a decrease in pH, electrical conductivity, cations, anions, some heavy metals, nitrate, and phosphorus, with the optimum depth being 10 cm. Furthermore, the effectiveness of Azolla in treating wastewater was evaluated and its use for irrigation purposes.
