Abstract :

In this research an analysis about a modified Ludzack Ettinger plant is developed for domewastes. The plant is modelled and simulated in Super Pro Design and it is composed by grid, anoxic reactor, aerobic reactor, settler and filter press. A factorial design, according Yateâ??s algoritm, at 2 levels is developed considering 4 factors as: the resident time of anoxic reactor (factor A), the resident time of aerobic reactor (factor B), internal recycle ratio (factor C), external recycle ratio (factor D). The concentration of NH3, TKN, NO3, total nitrogen, COD, BOD5, in addition to the SRT of anoxic and aerobic reactors are the analyzed responses. Results show that for the concentration of NH3 factors B, C, D and interactions AB, BC, BD, ABD, CD are significant. For the concentration of TKN factors B, C, A and interactions BD, BC, BCD are significant. For the concentration of NO3 factors B, C, D are significant. For the concentration of total nitrogen factors B, C, D, A are significant. For the concentration of COD factors B, C, D and interactions BC, BD, BCD are significant while for the concentration of BOD5 all main factors and interactions AB, AC, BC, ABC, BD, CD, BCD are significant. For the SRT of anoxic reactor all main factors and interactions AB, AC, BC, ABC, AD, BD, CD, ACD are significant. For the SRT of anaerobic reactor factor B, C, D and interactions BC, BD, CD, BCD are significant.
