Genesis AEC recently optimized a complex high purity water system using a digital twin to ensure long-term integrity and performance. Our client, a mission-critical government research facility, required a rigorous hydraulic validation of its existing high purity water system. The facility’s complex infrastructure spans 14 floors, featuring a Reverse Osmosis (RO) generation plant on the 14th floor feeding 12 floors of laboratory sinks through an intricate network of North and South wing sub-loops.
The primary challenge involved transitioning the system to a recirculating faucet design to eliminate “dead legs”—stagnant zones prone to biofilm proliferation. With inconsistencies in legacy field data and circular references in original documentation, the client turned to Genesis to provide a data-driven path toward system integrity.
Optimization & Risk Mitigation
Genesis AEC developed a high-fidelity Digital Twin hydraulic model using PIPE-FLO to mathematically represent the system’s architecture. This allowed our team to simulate the impact of design changes without disrupting live research operations.
Technical focus areas included:
-
Nodal Analysis: Resolving legacy documentation errors to establish a reliable hydraulic baseline.
-
Velocity & Reynolds Number Validation: Simulating flow conditions to ensure turbulent flow was maintained across all elevations, preventing the laminar conditions that favor bacterial adhesion.
-
Component Modeling: Quantifying the pressure drop and flow redistribution resulting from the installation of recirculating faucets.
-
Pump Curve Optimization: Evaluating the impact of motor and impeller modifications to optimize the system’s operating point and energy efficiency.
The Results
The Digital Twin served as a predictive “sandbox,” providing the client with a comprehensive roadmap for system optimization:
-
Precision Engineering: Accurately predicted the hydraulic effects of new hardware, ensuring compliance with strict purity requirements.
-
Risk Mitigation: Pinpointed specific low-velocity nodes, allowing for targeted interventions to prevent biofilm growth.
-
Operational Efficiency: Facilitated the evaluation of pump performance, unlocking untapped potential for enhanced system dynamics.
-
Informed Decision Making: Empowered the client to adjust internal quality standards based on verified, simulated hydraulic data.
