ATAL Biological Aerated Filter (ABAF)
ATAL Biological Aerated Filter (ABAF) is a highly compacted attached growth activated sludge process which combines biological treatment, nutrient removal and filtration. It reduces the footprint as compared with conventional methods and the honeycomb surface with its large surface area enhances the biological treatment of organic substances removal. The ABAF can be applied for various processes including carbon removal process, nitrification process and denitrification process. It has also been designed to have a long life and save on the capital cost.
