Abstract
Characteristic of hydraulic loading rate and organic matter degradation rate constant (k) were reviewed applying Atmosphere-Exposed Biofilm to brewery wastewater treatment. Atmosphere -Exposed Biofilm can purchase in small business with low financial expenses. The characteristic of hydraulic loading rate was investigated by controlling hydraulic loading rate of 17.0, 25.3, 33.7, 42.0, 50.3, 58.7m3/m2/d and it was determined that the optimal hydraulic loading rate was 33.7 m3/m2/d. Organic matter degradation rate constant (k) was determined by different hydraulic loading rate of 17.0, 25.3, 33.7m3/m2/d and media packing length of 0.15, 0.3, 0.45m. In result, organic matter degradation rate constant was 0.0554 for 500mg/L of BOD5 influent concentration. The experimental value and the predictive value of BOD5 removal efficiency using Eckenfelder formula were analyzed comparatively. The correlation (R2) between experimental value and the predictive value was 0.87 showing relatively good interrelation in 25.3m3/m2/d of hydraulic loading rate. Therefore it was considered that the treatment efficiency of Atmosphere- Exposed Biofilm could be estimated more accurately using Eckenfelder model in 25.3m3/m2/d of hydraulic loading rate.
