Summary

The concentration decrease of various pure organic compounds added to suspensions of washed activated sludge has been measured. The following observations are reported:

  1. (I)

    The substrates used in this investigation are eliminatedin proportion to the aeration time of the substrate-sludge mixture (enzymatic adaptations not accounted for). An exponential concentration decrease is observed with polymolecular substrates like peptone or with substrate mixtures when unspecific concentration parameters such as BOD or organic nitrogen etc. are applied. Nonlinear elimination curves are interpreted as the resultant of the individual linear elimination functions characteristic for each substance present in a waste.

  2. (2)

    The elimination rates of pure substances added to suspension of the same activated sludge are independent from the initial substrate concentration and are proportional to the sludge concentration.

  3. (3)

    The effect of theoxygen tension in the sludge suspension on the elimination rate varies with the kind of substrate. It is concluded that the obvious dependance of the purification efficiency of an activated sludge plant from the oxygen tension in the aeration basin is indirect. It is probably caused by shifts of the species composition of the sludge in accordance with oxygen concentration.

  4. (4)

    The climination rate of a substrate depends largely on the degree of sociological adaptation of the sludge to the milieu in which the substrate is presented.

  5. (5)

    Specific elimination rates (mg substrate/g sludge.h) of a variety of pure substances are presented and the practical significance of such figures is discussed.
