Abstract : Effectiveness Of Rbc System On Wwtp (Wastewater Treatment Plant) Pekapuran Raya Wt (Wastewater Treatment) Local Company Banjarmasin To Reduce Bod Contents. Increased household activities lead to increase the volume of waste generated over time. Annually, the household waste volume increases 5 million m3. WT Local Company Banjarmasin is a wastewater management company that performs domestic sewage treatment (feces) Banjarmasin city. Application of waste treatment technology on WWTP Banjarmasin is RBC system. This study aimed to determine the effectiveness of RBC system on WT Local Company Banjarmasin to reduce BOD (Biological Oxygen Demand). This type of study was analytic.

Sample was wastewater taken inlet and outlet pipe tanks. The result showed BOD (Biological Oxygen Demand) contents in the wastewater sample before it was processed of 130.97 mg/L, 116.98 mg/L, and 193.45 mg/l. After it was processed of 13.81 mg/L, 20.138 mg/L, and 30.216 mg/L.
