- Abstract
Oxidation Ditch Algae Reactor (ODAR) is a wastewater treatment reactor utilizing symbiosis between algal cultures and bacteria. ODAR reactors have large circular basin equipped with aerators. Pathogenic Escherichia coli is believed to mostly live in the contaminated area, which it could influence human health. This research conducted to analyze the performance of ODAR to remove nutrient and Escherichia Coli in grey water and artificial wastewater system. The study was conducted for 26 days with two batches: grey water and artificial wastewater with a mixture of fertilizer and sugar. Algae cell is measured with chlorophyll-a. Nutrient as ammonia and phosphate was measured. E coli removal was analyzed as MPN/100mL. Environmental condition parameter such as pH, dissolved oxygen, and light intensity to determine the mayor consequent of nutrient and E coli removal. The results showed ODAR capability to reduce ammonia and phosphat2 in grey water by 53,58% and 41,15% with the initial concentration 4,14 mg/l and 2,43 mg/l. As for the artificial wastewater, the removal efficiency for ammonia and phosphate is 59,7% and 59,15 % with the initial concentration 23,68 mg/l and 20,50 mg/L. Removal of E coli due to a lack of nutrients or organic compounds and high light exposure. This is strengthened by its existence of increasing chlorophyll concentration. E coli concentration decrease on grey water reached 98% and the artificial wastewater by 72%. This demonstrates the ability of Oxidation Ditch Algae Reactor (ODAR) in reducing the concentration of Escherichia Coli is reached within about 6 days
