Bioremediation of eutrophicated scenery water by Alcaligenes faecalis

Nowadays, eutrophication of the receiving waterbodies is a serious problem worldwide. Increased production of algae can result in undesirable effects on water quality, biodiversity, and health. This paper gives an introduction to contaminated characteristics, side-effects, and various methods of eutrophication in waterbodies, and discussion of in situ bioremediation to control eutrophication. The study was carried out to bioremediate eutrophicated scenery waterbody in greenhouse by adding of Alcaligenes faecalis suspended liquid (0.05⁰/₀₀> 0.1%oor 0.2⁰/₀₀). It was indicated that the total nitrogen (TN), total phosphorus (TP), and NTU were significantly reduced. When the quantity of consortium added was 0.1⁰/₀₀, it showed the highest removal efficiencies of TN and TP. By further research, the results indicated that TN, and TP were significantly reduced. At application rate of 0.1%o, Alcaligenes faecalis could effectively remove nitrogen, phosphorus, and alga in the body was basically controlled.
