Phytoremediation capability by azolla pinnata in aquaculture wastewater treatment

Abstract

The issue of lack of clean water sources is one of the main problems today. Pollutants in the water is one of the contributors to the problem. One of the major alternatives in the removal of pollutants from wastewater is through phytoremediation. The objective of this research was to determine the efficiency of phytoremediation method in treating wastewater using Azolla pinnata. The efficacy of A. Pinnata to absorb nutrients is dependent on the quality of wastewater and the quantity of A. Pinnata. Further, an experiment to determine the A. Pinnata biomass by phytoremediation method was carried out. The results of this study show that ammonia and phosphate were the main parameters in determining the effectiveness of aquaculture wastewater treatment using A. Pinnata. The results showed a drastic decline in the ammonia when the wastewater was treated with A. Pinnata from the average reading value of 7.47 to 1.67 mg/L. Meanwhile, phosphate concentration also showed a drastic decline after the wastewater was treated with A. Pinnata from the average value of 5.73 to 1.22 mg/L. The results of treatment of aquaculture wastewater by using phytoremediation of A. Pinnata was able to show changes due to an increase in biomass with the highest value of 147.26 gram.
