Wastewater Treatment by Azolla: A review

Water is vital for humans and other living things, but water pollution has become a significant issue today. Various anthropogenic agricultural, industrial, home activities produce multiple organic inorganic substances dissolved or suspended in water. The goal of wastewater treatment thus twofold: to reduce while also maintaining the supply demand. It based on three 3 Rs: reduce, reuse, recycle. However, many methods used are ineffective expensive. As result, purification matter great interest. Eco-friendly approaches essential among new technologies techniques tested treatment. Aquatic macrophytes treat by accumulating harmful metals nutrients. Like filters, variety aquatic floats can be suggested. Azolla one them, it been decades. Researchers have discovered that Chemical Oxygen Demand (COD), Biochemical (BOD), nitrogen, phosphorus, heavy metal concentrations wastewater; therefore, utilized produces lot biomasses wastewater. use reducing eutrophication lakes streams benefits discussed this study. According literature, high growth rate, with doubling date 2-4 days. Azolla's cell wall composed pectin, which affinity adsorption substances. serves as "biofilter" during way.
