MEMBRANES AUTOPSY SERVICES

---

Membrane-based water treatment systems, such as reverse osmosis (RO) and nanofiltration (NF), are critical technologies used across industries and communities to provide high-quality water. However, these membranes are sensitive to operational conditions, raw water quality, and maintenance practices. Over time, they can develop issues such as fouling, scaling, or mechanical damage, all of which reduce system efficiency and increase operating costs.

At IWS, we provide specialized membrane troubleshooting services designed to detect problems early, minimize downtime, and extend the lifespan of your membranes. Our proven approach combines hands-on inspection with performance analysis, allowing us to deliver accurate diagnoses and effective solutions tailored to your system.

Troubleshooting a membrane system requires precision and expertise. Our step-by-step approach ensures that every element is carefully examined for operational or performance issues.

1. Careful opening of the membrane element – We ensure the element is opened and handled with care to prevent additional damage during inspection.
2. Thorough examination – Each part of the membrane is carefully checked for signs of fouling, scaling, or wear.
3. Detailed diagnosis – Using our expertise, we identify patterns that point to the root cause of the problem—whether chemical, mechanical, or operational.
4. Corrective recommendations – After identifying the issue, we provide a clear set of recommendations to restore efficiency and prevent future problems.

This process not only addresses the immediate issue but also helps operators understand how to adjust system operation and maintenance practices to avoid recurring problems.

Reverse osmosis membranes are widely used in municipal water treatment, industrial processes, and desalination plants. However, they are also prone to specific issues that, if left unaddressed, can significantly impact performance.

During troubleshooting, we focus on:

• Assessing element integrity – Detecting cracks, tears, or other physical damage that may compromise salt rejection and water quality.
• Identifying scaling patterns – Scaling caused by calcium, silica, or other dissolved minerals can block water pathways, reducing flow and efficiency.
• Analyzing fouling deposits – Biological growth, organic matter, or colloidal particles can create fouling layers that decrease permeability.
• Evaluating cleaning history – Incorrect or insufficient chemical cleaning often accelerates membrane degradation.

By identifying these problems early, we help clients take corrective action, restore optimal water quality, and extend the operational life of their RO membranes.

Nanofiltration membranes are commonly used in softening applications, organics removal, and partial desalination processes. Although NF membranes are similar in structure to RO, their performance issues can differ.

Our troubleshooting for NF membranes includes:

• Detecting partial clogging – Fine particles and organics can partially block the membrane, reducing flow and increasing pressure.
• Checking for membrane degradation – Exposure to oxidants or improper chemical use can damage the membrane surface and reduce performance.
• Identifying operational inefficiencies – Imbalances in recovery ratios, pressure settings, or pretreatment can cause unnecessary strain on NF membranes.
• Recommending tailored solutions – Based on our findings, we develop corrective actions that restore performance and reduce the risk of future issues.

With the right adjustments, NF membranes can maintain efficiency for longer periods, reducing the need for costly replacements.

Membrane troubleshooting is not just about fixing immediate issues—it is about ensuring long-term system optimization. Clients who use our services gain multiple benefits:

• Minimized downtime – Early detection prevents small issues from escalating into major failures that halt production.
• Lower maintenance costs – Identifying the root cause reduces unnecessary cleaning, repairs, and replacements.
• Extended membrane lifespan – With proper troubleshooting and adjustments, membranes operate longer before needing replacement.
• Improved water quality – Restoring membrane performance ensures that treated water meets required standards.
• Optimized operations – Recommendations for better operation and maintenance practices improve overall plant reliability.

These benefits translate into significant financial savings and improved system sustainability.

Troubleshooting is a critical component of membrane system optimization. While design evaluation, monitoring, and preventative maintenance are all important, the ability to diagnose and correct problems when they arise ensures the system continues to perform efficiently.

At IWS, troubleshooting is always paired with:

• Data analysis to confirm findings with real-time performance trends
• Training for operators to help them recognize early warning signs
• Recommendations for SOP updates to standardize corrective measures
• Long-term strategies to prevent recurring issues

This comprehensive approach makes troubleshooting not just a repair service, but a performance improvement tool.

Over the years, we have encountered a wide range of problems in RO and NF systems. The most common include:

• Fouling by biological growth – Biofilms reducing membrane permeability.
• Scaling deposits – Mineral buildup reducing recovery and increasing pressure.
• Mechanical damage – Tears, cracks, or abrasion affecting salt rejection.
• Oxidative damage – Chlorine or oxidants degrading the membrane surface.
• Improper cleaning protocols – Wrong chemicals or procedures damaging the membrane.
• Design flaws in pretreatment – Inadequate filtration leading to premature fouling.

By identifying these issues, we provide both immediate corrective action and preventive strategies to protect future performance.

Our troubleshooting services stand out because they are:

• Comprehensive – We go beyond visual inspection, using operational data and historical performance records to identify problems.
• Specialized – Our team has deep expertise in both RO and NF membrane systems.
• Cost-effective – By solving problems early, we help clients avoid major expenses.
• Educational – We train operators throughout the process, building in-house expertise.
• Results-driven – Our goal is always to restore performance and extend membrane life.
