Shimming Procedure

Summary

BEL Shimming Procedure

This document outlines the procedure for shimming BEL Pressure Vessels.

Procedure Steps

1. Close the vessel on the reject side.
2. Load the membranes from the feed side to the reject side.
3. Remove the adapter from the end cap and remove the O-rings from the membrane side.
4. Settle the adapter (without O-rings on the membrane side) into the end cap.
   • Note 1: Keep the adapter O-ring at the end cap side.
   • Note 2: Apply lubricant (glycerin) on the adapter O-ring, at the end cap side.
5. Remove the seal for the end cap.
6. Push the adapter into the end cap until the edge of the seal for the adapter reaches the end cap hole to place it.
   • Note 3: Do not push the adapter too much into the end cap hole.
7. Insert the kit (end cap – adapter) into the vessel.
   • Note 4: Insert the kit slowly until point "A" makes contact with point "B".
8. As the adapter has no O-ring on the membrane side, the adapter will be placed into the membrane permeate tube without any resistance.
   • Note 5: The adapter will keep the same position in the end cap hole.
9. Keep pushing the end cap until it reaches its final position into the vessel.
   • Note 6: In the process of pushing, the adapter will move into the end cap hole.
10. Remove the kit (end cap – adapter) and measure the distance "X". To avoid any possible mismatch with tolerances, add one additional 1 mm shimming disk. The distance "X+1mm" is the real space to be shimmed with disk spacers.
11. Repeat this operation with every vessel to obtain the real shimming distance for each vessel.
