Innovative sensor technology
Implementation
of innovative sensor technology and control concepts in nutrient
removal plants The implementation of measuring and control systems
on wastewater treatment plants (WWTP) in practice is still a difficult
task. While in the academic community sophisticated control strategies
are discussed, there are a lot of problems to operate even simplest
control concepts and particularly to keep the system running. The reasons
can be related to technical problems, mainly from the measuring equipment,
and socio-economic difficulties. The latter results from a low priority
of these systems by the plant staff, caused by inadequate incentives,
the overwhelming daily business and partly by a lack of knowledge of
the processes. Strongly needed quality control concepts for the measuring
devices are not existent or inefficient in the daily business and the
control system design is often not adapted to the aspired aim. The dissertation
will investigate the main problems of control systems for aeration of
the biological stage of WWTP's in practice and give solutions, which
are applicable on the plants. To overcome the problems with inaccurate
data a concept will be proposed to make the quality control of the measuring
equipment more efficient. For an optimization of the design process
of measuring and control systems dynamic simulation is a suitable tool,
the needed biological, sensor and controller models should be developed
and validated.
