N2  - Combined treatment of septage and wastewater, was  investigated in a series of pilot-scale waste stabilization ponds  (WSP) , under ambient conditions.  The system consisted of three ponds in series, a facultative pond followed by two aerobic ponds. Septage was fed manually to the facultative pond (pond 1) at 0%, 23, 10%, and 20% of wastewater volume. The pond performance in term of physical, chemical. and  biological characteristics of the effluent was evaluated. The  results of the experiment snowed that a mixing ratio of 10 part of septage with 90 part of wastewater. was optimum, corresponding to a 78.4% reduction in BOD and 99.9% removal of fecal coliforms  The septage addition to the pond contributed nutrients to the pond water, resulting faster algal growth as was evidenced by chlorophyll-a concentrations .  Septage was found. to exert a significant influence on the  BOD-removal kinetics. An attempt was made to describe this effect in the form of a mathematical model. The developed  mathematical model was verified using the data of the present study and the data reported by ARIFIN (1982) .The model showed a considerable agreement between the predicted and experimental value of the K with a correlation coefficient  of O. 9596.  This empirical. relationship can be used to design a single-cell  pond receiving septage mixed with wastewater. A design example illustrating the model application is presented
