The AQUIS Water Quality module gives you full overview of the chemical
composition in every part of the water network in order to preserve the
right water quality. You can follow and track the water throughout the
network and be informed about the composition in every node. The AQUIS water
quality simulation engine allows speedy, accurate evaluation of the most
complex water networks.
AQUIS Operation uses live data from an online water
analysis as basis for predicting and analyzing the
spread and origin of the pollutant. This reduces the
costly effects of a pollutant spreading in the water
distribution network.
New technology within online water quality analysis is evolving rapidly. We also
see an ever increasing focus on providing drinking water of higher quality as well
as on the ability to avoid the extremely costly effects of pollution. These effects can
be the cost for analysis, cleaning, consultancy and provision of alternative water
sources, but also have direct impact on the consumers. As an example the need for
hospitalization can be reduced by rapid reaction and information.
In general, this new functionality allows the water utility to react quickly and
correct based on real-time information – and to provide the consumers and other
stakeholders with qualified information.
Using online quality analyses
The online data is transmitted from the online analyzer to AQUIS Operation via the
SCADA system. An analyzer dashboard shows the status of each instrument, as can
be seen with the colors shown in the overleaf display. By clicking on the specific
analyzer you can see the e-coli level, or any other parameter being measured, as
well as the historical data in comparison to the threshold value.
Prediction of spread of a pollution
Once an analyzer exceeds an alarm you are able to track the spreading of the
water from that point and further into the distribution network. This allows you to
quickly see who will be affected. AQUIS Operation can take into account that the
analysis has a certain delay time, and include this when calculating the spreading
of the pollutant. By drawing a line around the infected area, AQUIS Operation
advises which consumers are affected. It even allows the operator to submit text
messages to the affected consumers, advising them to boil the water, hence
perhaps avoiding people drinking polluted water.
Limiting the spread of a pollution
AQUIS Operation also has the facility of advising which valves have to be closed
to section of a specific area or zone, enabling the operator to react quickly in his
pursuit of reducing the spread of the contaminant in the network.
Identification of the source of the pollution
AQUIS Operation can analyze where the water at the measuring point comes from.
This can be from a number of sources or just one. In combination with the other
analyzers the most likely source of contamination is identified by extrapolating the
data. As the model is always reflecting the real life situation, this can save a lot of
money and precious time in critical situations.
