Part I: Preparation
1.1 Prepare all tools that may be used during the construction process;
1.2 Clean the upstream water inlet pipeline;
1.3 Carefully evaluate the quality of the incoming water;
1.4 Check whether the pipeline has leaks;
1.5 Prepare water-soluble lubricant (chemically pure glycerin);
1.6 Ensure that all parts and chemicals used are complete;
1.7 Check the operation of the pre-treatment system and the normal water output.
Part II: Dismantling of old reverse osmosis membrane and installation of new membrane
· Dismantle the pressure vessel and store parts systematically.
· Remove the old membrane and rinse the pressure vessel.
· Check the brine seal ring on the new membrane for correct orientation.
· Insert the new membrane element into the pressure vessel and apply lubricant to the "O" ring of the connecting pipe.
· Repeat for additional membrane elements until all are installed.
· Install the thrust ring and check the "O" ring on the element adapter.
· Align and install the end plate clamping ring and adjust the gap with an adjustment sheet.
· Repeat for all pressure vessels and connect external pipelines.
Part III: Equipment Debugging
1. Prepare for debugging: calibrate instruments, set sampling points, check connections, and test rotating equipment.
2. Open discharge valves and adjust the high-pressure pump outlet valve.
3. Use low-pressure pre-treated water to eliminate air from the system and check for leaks.
4. Perform low-pressure flushing for at least 6 hours or follow a soaking procedure.
5. Confirm all valves are correctly set and start the high-pressure pump with controlled flow.
6. Gradually open the high-pressure pump outlet valve and adjust recovery rates.
7. Check chemical dosages and measure inlet water pH.
8. After 1 hour of operation, record parameters and transition to automatic mode.
9. After 24-48 hours, review system performance data and confirm normal operation to complete construction.
