We undertake the modeling and dynamic simulation
of water treatment plant to support the design and development of plant
hydraulic behaviour and process and operational controls.|
By modeling the controlled flows of water from source of
supply through treatment units such as flocculators, filters, chlorinators,
intermediate storage vessels and pumps through to treated-water delivery,
our simulations can predict the behaviour of continuous and sequence process
controls and their effects on water flows, pressures and hold-ups in
Past simulations have been used to
-Sizing of vessels in the treatment path -
to minimize vessel capacities and construction costs while still coping
with changing operational and unusual flow conditions, such as plant trips.
Investigating hydraulic interaction; e.g.
between adjacent filters during washing operations.
Supporting plant commissioning – by
providing initial tuning parameters for feedback controllers of flows,
levels and pressures, and by revealing to commissioning engineers in advance
the significant behaviours to be expected from a new or modified plant.
Investigating commissioning problems – by
comparing actual behaviour with modeled behaviour – to help pinpoint the
likely sources of any deviations of actual plant behaviour from design
In accordance with our in-house
modeling and simulation engineering principles: we use only commercially
available, off-the-shelf, general-purpose dynamic simulation software as our
modeling environment. This ensures that our models are accessible to the
customer and can made available and adopted readily by the customer for
further in-house development, with the assurance of ongoing support from the
simulation software supplier.
For our simulation studies we use
Matlab® and Simulink™ –
possibly the worlds most popular general-purpose dynamic simulation software
Our models are aimed primarily at
simulating the behaviour of pressures, flows and accumulations (in vessels)
of water by means of dynamic models of pipe work, valves, pumps, vessels
etc. and their associated manual and automatic feedback and sequence
