Linear alkylbenzene sulfonate (LAS) represents one of active substance of surfactants in detergents of which in high concentrations may cause environmental pollutions. The aim of the research was to know the efficiency of exclusion of LAS and the rate of LAS degradation in detergent wastes by the anaerobic process at fixed bed reactor equipped with cross flow material. This research was done in Process Laboratory of Balai Teknologi Lingkungan BPPT PUSPIPTEK Serpong. Reactor operation was done through continuous process with close circulation, up flow and 5 hours Rate Time Hour (RTH). Exclusion of LAS of detergent waste was recorded for 17 days. The degree of acidity after the process without inoculum (P1.0) was to 8.45, and for an anaerob condition with added inoculum (P1.1) was 7.88. The efficiency of the highest exclusion of CO soluble was equal to 80.96% (P1.1) with effluent 476 mg/L, and 76.81 % (P1.0) with effluent 531 mg/L. The exclusion of LAS of detergent wastes was 99.19% (P1.1) with LAS effluent equal to 17.51 mg/L and 98.3% (P1.0) with LAS effluent equal to 27.84 mg/L. The maximum rate of LAS surfactant degradationunt 0.95 ppm/day (P1.1) and 0.44 ppm/day (P1.0).
