  • Conventional Activated Sludge Process

  • Upflow Anaerobic Sludge Blanket (UASB) Process

  • Extended Aeration Process

  • Sequential Batch Reactor (SBR) Process

  • Moving Bio Batch Reactor (MBBR) Process

  • Anaerobic, Anoxic & Oxic (A2O) Activated Sludge process for biological nutrient removal
