Fixation of Sludge. As mentioned earlier, most of our work to date has been with nonradioactive, simulated sludge. Since sludge composition can vary markedly from tank to tank, we formulated these three types of simulated sludge based on our knowledge of plant processes and some preliminary sludge analyses (Table VI). We expect that these will cover the range of compositions encountered with actual waste. [Pg.18]

FIGURE 3.10. Comparison between average values of COD-fractions in wastewater generally determined by different methods and with different objectives, either for simulation of the processes in activated sludge or for simulation of wastewater processes in sewers. Typical percentages of the different fractions are shown in brackets (Henze et al 1995a Hvitved-Jacobsen et al., 1999). [Pg.56]

Based on this modified activated sludge concept, it was possible to produce acceptable model simulation results for the water-phase processes of the heterotrophic carbon transformations in sewers. However, problems were identified for the description of the heterotrophic biomass decay. A major problem was the magnitude of the 1-order decay rate constant with respect to the biomass concentration. Henze et al. (1987) and Kappeler and Gujer (1992)... [Pg.103]

The University of Dayton Research Institute has developed a photo-thermal detoxification unit (PDU) that can completely destroy vapor-phase organic contaminants from soil, sludge, and aqueous streams. The PDU is a patented technology that is available for licensing. Engineering plans for construction of a PDU are commercially available. The technology has not been demonstrated on a field scale but has been used in laboratory studies of simulated wastes. [Pg.1099]

Biological treatment simulations consist of either continuous (CAS) or semicontinuous (SCAS) activated sludge tests that use either synthetic or natural sewage. The sewage or initial sewage inoculum usually is taken from a domestic wastewater treatment plant in order to reduce variability (industrial wastewater plants may contain very special chemical loadings) and to simulate treatment of consumer products. If treatability information in an industrial wastewater plant is desired, samples from the plant may be used. [Pg.310]
