Short definition
Fluid planning refers to the systematic planning and documentation of all fluid-carrying systems in a process plant. It includes the graphical representation of pipelines, fittings, pumps, valves and measuring equipment as well as their functional assignment. As part of the Automation technology the fluid plan creation forms the basis for the integration of sensors, actuators and control components. It serves as an interface between mechanical design and process control technology.
Functional principle
The fluid plan is created in accordance with standardized norms such as DIN EN ISO 10628 or VDI 2066 and includes several levels of detail - from the basic flow diagram to the process flow diagram (PFD) to the piping and instrumentation flow diagram (P&ID). All process-relevant components are assigned unique tag numbers and their functions are documented. The planning takes into account hydraulic parameters, pressure losses, volume flow distributions as well as safety and control requirements. Modern CAD systems enable integration with PLC programming and SCADA systems.
Areas of application
Fluid planning is essential for all industries with complex fluid-carrying processes. In membrane filtration technology in particular, it ensures the correct design of permeate, concentrate and rinsing circuits as well as the integration of automated CIP systems. The detailed documentation enables precise control of crossflow speeds, transmembrane pressures and backwash cycles.
Typical areas of application:
- Drinking water and waste water treatment plants
- Pharmaceutical production processes (GMP-compliant)
- Food and beverage industry
- Chemical process engineering
- Semiconductor and clean room technology
Summary
Professional fluid planning is the basis for efficient, safe and low-maintenance membrane filtration systems. It reduces planning errors, speeds up commissioning and facilitates subsequent integration into higher-level control systems such as TIA Portal or PCS 7. For plant manufacturers and engineers, it is an indispensable tool for quality assurance and meeting regulatory requirements.
