Abstract The sequencing batch reactor (SBR) technology possesses a high process flexibility
and treatment efficiency. Unfortunately, up to now most SBR plants are still using fixed timebased
sequential control (TSC), which can not react flexibly. Therefore, this paper will focus
on instrumentation, control and automation (ICA) for SBR plants, because with the help of
modern supervisory control and data acquisition (SCADA) systems and dynamic RTC it is
possible to operate SBR plants much more effectively.
Keywords Real-Time Control (RTC), SBR, Instrumentation, Control and Automation
Introduction
One of the several types of WWT technologies commonly used in the world (i.e. several
thousands), is the SBR technology, where all treatment processes take place in one single
reactor. In dependence of diurnal, weekly or seasonal variations in flow rate, load and sludge
characteristics it is possible to vary the sequences of the steps and the duration of phases in a
cycle. This leads in principle to a high flexibility of the SBR technology. To exploit the
advantages of (dump filled) SBR technology like flexibility, high metabolic activity and
good sludge settling properties etc. SCADA systems and powerful programmable logic
controllers (PLC) are required combined with flexible control strategies.
But in many cases the flexibility is not used because most of the SBR plants use fixed TSC.
