2.1. Carefully study the vessel engineering drawings for key dimensions and
technical requirements.
2.2. Design and manufacture rack according to engineering drawings and system
capacity. Independent support of both pressure vessel and manifolds shall be
considered in the design of the rack.
2.3. Check the integrity of the vessel, especially the inner surface of the vessel and
the sealing surface of the Feed/Concentrate ports.
2.4. Ensure enough space is reserved around the two ends of the vessel for
installation and removal of the membrane elements.
2.5. Mount the vessel on the provided saddles at the recommended span positions
shown on the engineering drawings.
2.6. Connect the vessel to the manifolds and/or to the next vessel while adjusting
each vessel and manifold to minimize misalignment at each end. (For details, see
“Chapter 4 Piping Connections”).
2.7. Install the strap assembly. Install the screws through the hole in the rack and
thread them into the strap locknut; use a torque wrench to tighten the screws
within 3~5N.m.
NOTE: Pressure vessels expand during pressurization, over tightening the
strap assemblies will damage the vessel.
2.8. Assemble end closure(For details, see “Head Assembly” in “Maintenance Guide”)
2.9. Install membrane elements(For details, see “Membrane Elements Installation”
in “Maintenance Guide”)
2.10. Install thrust ring at the downstream end of the vessel.
2.12. Connect the permeate port manifolds (For details, see “Piping Connections”)
2.13. Inspect the installation. Inspection includes but is not limited to the position of
the vessel, the end caps and pipelines connections. Please inspect according to
“Pre-Pressurizing Checking list” in Appendix 1.
2.14. Pressurize and run the system.
