2.5.5 Validation of Various Modeling of Aerobic Hybrid
Bioreactor
Most of the mathematical models on hybrid bioreactor were firstly illustrated using
one or more sets of available data for the purpose of analytical validation. Glimpses
of such analytical validation are presented in Table 2.1.
At the same time, a few laboratory-scale studies were also carried out on the
hybrid bioreactor developed by various researchers. Consequently, they compared
the experimental observations in respect of relevant parameters with those available
from the respective models. A comparison of output parameters, viz. S w , J, L e and
L f , derived from various models and concerned experimental observations is also
presented in Table 2.2.
2.6 Treatability of Municipal Wastewater
2.6.1 Characteristics of Municipal Wastewater
The municipal wastewater exhibits more or less uniform characteristics for a particular location. However, the characteristic profile may be changed depending on food
habit and lifestyle. There are so many limitations reporting characterization of municipal wastewater prior to their respective treatability study. The glimpses of all such
characterization reports are listed in Table 2.3.
2.6.2 Scope of Treatment of Municipal Wastewater Using
Activated Sludge Process and Its Modification
The most common suspended-growth process used for municipal wastewater treatment is the activated sludge process. The removal of BOD is accomplished by means
of microbial uptake under suspended-growth state. This biological method essentially
is an aerobic process and takes place in the aeration tank, with the help of oxygen
provided through aeration. The microbial growth leads to formation of biomass flocs,
which are\settleable in the secondary clarifier. Hence, the clarified effluent is obtained
through the effluent line. Domestic wastewater of all types is treated with the help of
activated sludge process but mainly for removal of COD, BOD and TSS. BOD and
TSS removal efficiencies of the activated sludge plant (Aeration tank + Secondary
clarifier) are 91.27% and 86.76%, respectively (Sundara kumar et al. 2010).
For denitrification of municipal wastewater, Modified Ludzack Ettinger (MLE)
process was used which comprised anoxic and aerobic tank along with secondary
clarifier, and return activated sludge line from secondary clarifier. In this process by
