Pavlostathis where, fd ϭ net biodegradable fraction of active biomass. 4 Estimation of biokinetic coefficients The above-developed relationships based on the Monod model require the values of four biokinetic coefficients: Y, k, Ks, and b. The values of these coefficients (assumed to be constant for a particular biological system), can be found as follows: from literature; evaluated experimentally for a batch or a continuous-flow system (Metcalf & Eddy Inc. 6, values of Y and k only). 20) can be used to perform a non-linear regression to simultaneously estimate the values of the four -biokinetic coefficients.

2 is typically observed with four, more or less distinct phases. Lag phase After the addition of a small quantity (compared to the substrate mass) of inoculum to the culture medium, the organisms must adjust to the new environment before they begin to divide. The lag phase may be required for the production of inducible enzymes, as well as the replacement and/or generation of growth factors not previously required for microbial growth. 4) where n ϭ number of generations or replications. By defining td ϭ minimum generation or doubling time, then n ϭ t/td, where t ϭ time.

For example, both ammonia and oxygen can be limiting in the nitrification process. 37) where S1, S2, …, Sn ϭ substrate concentrations (M LϪ3); Ks1, Ks2,…, Ksn ϭ halfsaturation coefficients for the respective substrates (M LϪ3). , saturation). 39) where So ϭ initial substrate concentration (or influent substrate concentration for a continuous-flow system (M/L3)). G. Pavlostathis where g ϭ constant (unitless). When Ϫg ϭ 1, the Moser model reverts to the Monod model. 42) where B ϭ constant (Msubstrate/Mbiomass).
