Abstract

The study involved a laboratory experiment on the use of Azolla pinnata in the phytoremediation of a textile waste water from United Nigeria Textile. The physiochemical characteristics of the waste water were determined before and after the treatment. The experiment lasted for three weeks and the rate of reduction was recorded. The highest rate of mean reduction was for heavy metals (Al, Mn, Ni and Cu). Other physiochemical parameters tested include Total Dissolved Solids (TDS), Chemical Oxygen Demand (COD), Nitrate, Biochemical Oxygen demand (BOD), Total suspended Solids (TSS), Dissolved Oxygen (DO), Sulphide, Phosphate, Oil and Grease, Ammonia and the pH. Azolla pinnata is a suitable candidate for effective phytoremediation of water from Kakuri stream.
