Objectives
• Experience the plant in a virtual
environment
• Test new logic off-line
• Reduce startup cost
→ Commissioning without tying up
plant resources by using simulation
• Access to the (simulated) process
for multiple disciplines
• Validate new / modified SOPs
(Batch, MES, manual)
• Emulate plant occupation and timing
• Replay of process data

High-Fidelity Predictive
Models for Water treatment Plants
• Enable rapid exploration of the
process decision space for
optimizing of water treatment
process design and operation
• Provide accurate information for
reducing energy and chemical
consumption
• Support informed decision
making about current and future
plant capacity and minimizing
capital and operational costs

Flowsheets and libraries also for complex water treatment plants involving
processes like
• Aerobic process, especially aeration basin or activated sludge process
• Anoxic / aerobic selector
• Clarifier / Thickener, sludge decanter, anaerobic solid / sludge digester
• Biogas treatment, e.g. scrubber and utilization e.g. boiler, CHP
• Membrane filtration, membrane bio reactor (MBR)
• Sludge thermal hydrolysis
• Flotation / coagulation / flocculation
• Ion exchange
• Granulated sludge
• Anaerobic reactor (UASB or similar high rate anaerobic WWT processes)
• SBR
Optimizer includes integer / discrete decisions on how to operate different
treatment / many lines towards maximum efficiency

• gPROMS Web Applications Plattform (gWAP) allows to publish a model
behind an easy-to-use web interface
• Enables ‚non-modelling users‘ across the organization (e.g. operating
personnel) to use the information in high-fidelity models for decision
support and continuous optimization
• Easy-to-use interface
