Abstract

Slaughterhouse produces wastewater eith high organic matters which includes blood, fat, proteins, and solids. The wastewater from Ciroyom Slaughterhouse in Bandung, Indonesia has the average COD of 3118.95 mg/L, suitable for aerobic process. Dissolved Air Floatation was used as a pre-treatment to eliminate the high contents of oils and fats in Slaughterhouse wastewater. This research was conducted to study the kinetics of low (1500mg/L COD) and high (3500 mg/L COD) organic loading adjustment and 2 variations of reaction to stabilization time (4 h reaction to 4 h stabilization and 2 h reaction to 6 h stabilization). The lab scale aerobic SBR was operated in 3 continuous cycles of 12 hours each. The entire cycle consist of fill ( 1 hour), react (4 or 2 hour), settle and decant (3 hour), and stabilization/idle (4 or 6 hours). The kinetics parameters of Y (growth yield coefficient), q (specific substrate uptake rate), and µ (specific growth rate) were compared between those four conditions. The best cycle kinetics for organic carbon removal was achieved in 3500 mg/L COD with 2 h reaction to 6 h stabilization time with Y, q, and µ of 0.36.38 mg VSS/mg COD, 0.0255h-1, and 0.007 h-1, respectively.
