Equipment Profile Neutral Engineering Reference
Pressure Vessels
Sealed cylindrical housings that hold one or more spiral-wound RO membrane elements in series and withstand the system operating pressure.
Engineering Application
Contain the membrane elements and distribute feed flow and permeate collection. Vessel staging sets the hydraulic path of a train and, together with element count per vessel, defines the pressure profile and achievable recovery.
Key Parameters
| Parameter | Unit |
|---|---|
| Number of elements per vessel | elements |
| Maximum working pressure | bar |
| Vessel diameter | inches |
