LAS and ABS are the detergent active compounds and their presence should always be monitored because they are pollutants. 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 this method was easier and very economical when compared with other processing methods. Before, biodegradation by Pseudomonasaeruginosa is done only for the treatment of LAS but on this study it is also conducted for the treatment of LAS and ABS. So it is necessary to determine optimum conditions. 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 CO2was127.6 mg / L.
