FATE MODEL PROGRAM

This program was developed at the University of Cincinnati,

Department of Chemical Engineering, under cooperative

agreement USEPA CR-812939. The program was developed by

L. Lai and C. Gao under the direction of

Dr. Rakesh Govind

Professor of Chemical Engineering

University of Cincinnati,Cincinnati, OH 45221

(513) 556-2666

and

Dr. Richard Dobbs

The FATE MODEL has been developed for predicting the fate of

organics in a completely mixed activated sludge treatment plant

operated under acclimated conditions. It has been validated using

experimental data from a pilot-scale facility and full scale

treament plants. The biodegradation kinetic constants for some

compounds were estimated using group contribution approach.

Applications of the model include: (1) assessment of

emissions of volatile organic compounds from wastewater treatment

plants, (2) estimation of the concentration of toxic compounds

associated with sludges, and (3) a general framework for estima-

ting the removal of toxic compounds during conventional primary/

activated sludge treatment. A detailed description of the FATE

MODEL has been published in Environmental Progress Vol.10, No. 1,

p.13-23, February (1991).
