  • Performance evaluation of an aerobic biofilter with high organics containing synthetic wastewater

    The organics removal performance of a lab-scale aerobic biofilter of volume 0.6 L was studied using synthetic wastewater and waste automobile tyre-tube beads as media. The column study was performed under Chemical Oxygen Demand (COD) in the range of 500-1500 mg/L at an empty bed contact time (EBCT) of 2 h. The treatability constant at 27°C was found to be 41.963. A maximum COD removal efficiency ...

  • Performance evaluation of a shaft–type hybrid bioreactor for the removal of carbonaceous organic matter

    In comparison to an activated sludge process, the organics removal performance of a lab–scale hybrid bioreactor of volume 14.5 L was studied using waste automobile tyre–tube beads as bio–carrier. Batch study was performed using synthetic wastewater with soluble chemical oxygen demand (COD) ranging between 1000–3500 m/L for a period up to 9 h under purely suspended growth as well as hybrid ...
