Biodegradation Of Linear Alkylbenzene Sulfonate (Las) And Alkylbenzene Sulfonat (Abs) By Pseudomonas Aeruginosa Bacteria

LAS and ABS are the detergent active compounds and the presence of its should always be monitored because they are pollutants. The accumulation of LAS and ABS is a toxic to various aquatic organisms and can form foam that can reduce the environmental aesthetics such as lowering dissolved oxygen content, and when foam is blown by the wind, it can spread microbial pathogens. Detergent treatment has been done by way of adsorption, flocculation, coagulation and advanced oxidation, but the process can produces unwanted sludge that need further processing. One alternative technology that is used to treat wastewater is biological treatment using the bacteria Pseudomonas aeruginosa, because detergent is an organic substance that derivatic accumulations cause increased COD and BOD so that the processing is very suitable to use biological techniques, besides biological treatment is very economical when compared with other processing method. With this method LAS and ABS was degradable to CO2 and H2O. In this study, LAS and ABS successfully degraded 99.73%. With the longer time CO2 formed was increasing, and the biggest CO2 at pH 7 and the 50th hour, concentration of CO2 was 127.6 mg / L.
