Powdered activated carbon treatment

Hard-to-degrade and toxic compounds in wastewater can be adsorbed by using activated carbon. Powdered activated carbon (PAC) treatment is mainly used to remove persistent organic compounds (e.g., pesticides and biocides) and organic compounds (e.g., AOX, BTEX, MAH, and PAHs). In this PAC treatment, the biological degradation process occurs undisturbed and with changing influent compositions. PAC is dosed into the aeration tank; the optimum is determined via experiments. Because during the process the sludge quantities increase, an additional system for sludge treatment may be required. Since the retention time of the added activated carbon depends on the age of the sludge in the system, the PAC process is difficult to control.

The presence of PAC improves sludge sedimentation. The more activated carbon that is added, the more sludge is produced. Care should be taken regarding dust formation. A disadvantage is the color (black sedimentation). The presence of activated carbon can influence the disposal possibilities for the excess sludge.
