Removing of Methylene Blue Dye from Wastewater by Interaction between Ceratophyllum demersum and Acinetobacter radioresistens

Abstract

The textile factories are one of the main important problem will generate water pollution therefore, to reduce the contaminant from wastewater before their discharge into environment. The current study included to investigate the removal of methylene blue dye by using of the aquatic plant Ceratophyllum demersu with Acinetobacter radioresistens bacteria. The best concentration of 30 mg/L of methylene blue dye was prepared to application in basins. Four basin were prepared used and fill by wastewater from river with 20 liters, 100 g plant weight and volume 900 ml of liquid nutrient medium containing bacterial growth. The visible spectrum of the four basins was read during a period of 0, 1, 5, 10 and 15 days from the start of the experiment. The percentage of treatment for the fifteen days was %78.53 for the basin contain plant while %58.48 basin the bacteria, 88.72% for the plan with bacteria, and 9.85% for the control basin.. The results proved that there is a noticeable difference when bacteria are involved with the plant in the treatment, and this proves that the interaction between bacteria and plants was higher to remove harmful compounds in the environment, including methylene blue dye.
