Installing New RO Membranes for Our 50 m³/Day Reverse Osmosis Project – A Behind-the-Scenes Look
At Machine 4 Africa, delivering reliable and high-performance water treatment systems is at the core of what we do. This week, our technical team successfully completed one of the key stages of our ongoing 50 m³/day Reverse Osmosis (RO) installation project for one of our valued clients: the installation of brand-new RO membranes.
Here’s a behind-the-scenes look at how the process unfolded and what it means for the performance of the system.
1. System Preparation and Safety Procedures
Before any membrane installation begins, our engineers follow a strict safety and system preparation protocol:
- The RO skid was fully isolated from power and water sources.
- All pressure vessels were depressurized and drained.
- The team conducted a thorough inspection of the pressure vessels, O-rings, end caps, and permeate tubes to ensure everything was in optimum condition before inserting the new membranes.
This preparation phase is crucial to prevent contamination, ensure operator safety, and guarantee a smooth installation.
2. Removal of Old or Temporary Membranes
For systems being upgraded or commissioned, careful removal of existing membranes is necessary.
Our technicians:
- Opened each vessel end cap.
- Gently extracted the old membranes using approved pull tools.
- Cleaned the vessels internally to remove any scaling, debris, or bio-film residue.
This ensures the new membranes operate in a clean and controlled environment for maximum lifespan.
3. Inspection and Lubrication of Components
Every component in the membrane vessel plays a vital role in water quality.
We inspected:
- Brine seals
- Interconnectors
- Permeate adaptors
- O-rings
Each was cleaned and lubricated using food-grade silicone lubricant to ensure smooth insertion and proper sealing, preventing bypass and ensuring correct flow through the membrane elements.
4. Installation of the New RO Membranes
This is the heart of the process.
Our engineers:
- Aligned each new membrane correctly with the brine seal facing upstream.
- Carefully inserted the membranes into the vessels to avoid damage.
- Ensured perfect interconnection between elements inside the vessel.
- Re-installed the end caps and secured them to the manufacturer-recommended torque settings.
Precision here is critical: proper alignment ensures optimal performance, high rejection rates, and stable output water quality.
5. System Re-Assembly and Leak Testing
After all membranes were installed:
- The team reconnected all pipes, fittings, and instrumentation.
- Conducted a low-pressure flush to remove any trapped air and check for leaks.
- Verified membrane seating, permeate flow, and pressure balance.
This ensures the system is ready for full-scale commissioning.
6. Initial Start-Up and Performance Checks
Once testing was complete, we ran the RO system at controlled pressure to monitor:
- Permeate flow rate
- Salt rejection
- Conductivity levels
- Pressure differential across each vessel
- Recovery rate
The first performance readings were excellent, confirming that the installation was done correctly and that the system will deliver consistent, high-quality water as designed.
