It can be considered that the removal of ABS from activated sludge units consists essentially of two phenomena. One is adsorption and the other is bio-degradation. This paper mainly describes the adsorption phenomenon.It is found that ABS adsorption on activated sludge has the following eqilibrium : [α-x]+[s]⇄[x]α : added ABS concentration x : adsopted ABS concentration on sludge s : sludge volume or([x])/([s])=K[α-x]K : constant This equation is equivalent to Freundlich's adsorption isotherm where 1/n is 1.x/s=ks^<1/n>However, it would seeme that if s is variable the following would be better x=c(e^<Ks>-1)When water containing ABS is added continuously to an aeration tank, ABS concentration of the effluent is as follows.c=A(1-e^<-1/(1+k).F/V.t>)c : ABS concentration of effluent A : ABS concentration of influent F : influent volume V : aeration tank volume t : time from begining of adding ABS From the above equation, as t becomes infinite, c approches to A. But from paractical results c is not equal to A at 24〜72 hours, probably because of new sludge being produce.
