Comparative Studies of Activated Sludge and Rotating Biological Disc Process (I).

Rotating Biological Discs process (RBD), as a relatively new system, required checking of utilization possibilities in treating different kinds of wastes. It was natural and necessary to compare this process with other methods, especially with the activated sludge process. The investigations concerned mainly economical aspects and technical conditions and were less concentrated on kinetic growth of microorganism or creation of biotic factors. ^{1 , 2 , 3 , 4 , 5}
