Module is add-on module for Process Advisor. It allows
Process Advisor to be connected to a real wastewater treatment
plant. Realtime Module activates two new menu choices on Process
Advisor: Realtime Data Analyses and Realtime Control. These choices
do exactly the same things as their offline-versions Recorded Data
Analyses and Control do - they analyze or control the treatment
process. The only difference is that they use real process
data instead of simulated data. Everything that's available
in offline-versions is available in realtime-versions in
real time. The following figure shows how the treatment
system can be implemented.
This is how the system works: The plant computer
reads measured data from sensors and sends it through direct cable
connection (COM ports) to a computer where Process Advisor is
running in realtime mode (analysis computer). On analysis computer,
various unobservable processes are made visible. If Process Advisor
is in analysis mode (Realtime Data Analysis menu option), it then
waits for the next set of samples to arrive. In control mode Process
Advisor attempts to stabilize the treatment process at references
set by plant operator. Based on measurement data, it generates
controls (optimal flows) and sends it back to plant computer, which
then adjusts flows accordingly.

With Process Advisor + Realtime Module you always know the
current state of the treatment plant. This leads to improved control
of the plant, which allows the plant to handle high loading without
sacrificing treatment process quality. This leads to big savings as
software is always vastly less expensive than increasing the
dimension of existing plant.
Knowledge of the current state of the treatment process greatly
simplifies the difficult job of running the plant (no more "blind
driving"). It also helps to improve the treatment process quality
and reduces the time required to recover the treatment process when
it goes unstable (better yet, with Realtime Module you might be able
to avoid this situation altogether).
You also benefit from Process Advisor + Realtime Module when
you're about to implement nitrification and/or phosphorous removal
on existing plant. It is very important to keep the carbon removal
process under tight control before implementing other, more
Various treatment process characteristics available in
real time. View the current state of the process (including
unobservable characteristics) or scroll back and see what the
process was up to a week ago.
Relatively easy to implement. If all equipment
is available, just set up the plant computer to send measurements
data to COM port on regular intervals (either 2, 3 or 6 minutes),
connect plant computer and analysis computer and you have
state-of-the-art analysis and diagnostics system!
Automatic control mode also available. In this mode the
treatment plant can be run unattended, since Process Advisor takes
care of stabilizing the treatment process at references set by plant

Robust and stable. Process Advisor is able to
detect if one or more of the sensors fail and continue operating by
ignoring these sensors.

Pricing and Availability
Realtime Module for Process Advisor is available now. Pricing
depends on what changes have to be made to Realtime Module to render
it compatible with your plant and what support options you would
like. Please contact
