Abstract:
In comparison to larger plants,
decentralized small size
wastewater treatment plants (DCWWTP)
face more pronounced
operational constraints such as
high load fluctuations, operation
and maintenance problems and
increased costs per capita. The
scarcity of historical data on the
performance of this type of plants
is generally associated to largely
unattended operation. Thus, it is
important to gain adequate
information for both performance
assessment and process control,
at controlled costs and adapted to
centralized supervision. For this,
the implementation of an expedite
framework for performance
monitoring and control is
proposed, using on-line data
obtained with robust instruments
and a simplified dynamic model
structure. Point, periodical
determination of value ranges for
some wastewater characteristics
and model parameters, using
respirometric assays, allows a
more robust modeling of the
biological treatment process in
these DC-WWTP.
