Advantages and Disadvantage of Activated Sludge Process - The main advantage of activated sludge process is that it requires less space than the biological filter. The second advantage is that a final effluent of high quality is produced such that it does not require high dilution for disposal.

There are two disadvantages. Since the incoming effluent is introduced at one end of the tank, the BOD value will be higher at this end than the other. Moreover, the microorganisms at this end will be physiologically more active than those at the other end. These defects are rectified in the complete mixing activated sludge process.
