Improved Efficiency
RO membrane cleaning removes fouling materials, restoring permeability for optimal water flow and high contaminant rejection. Cleaning membranes leads to an overall more efficient RO system.
Extended Lifespan
Regular cleaning prevents fouling and scaling that can damage RO membranes. Cleaning extends their operational life, reducing replacement frequency, saving costs and minimizing maintenance downtime.
Consistent Water Quality
Clean RO membranes remove salts, compounds, and contaminants to ensure high-quality water for various industries like food, pharmaceuticals, and healthcare where water quality affects product safety and quality.
Reduced Costs
Maintaining and cleaning RO membranes reduces costs from fouling and scaling. It improves system efficiency, lowers energy consumption, and reduces chemical cleanings.

Why clean your RO membranes?
Over time, reverse osmosis (RO) membranes accumulate contaminants such as scale, biofouling, and other deposits that reduce efficiency and water quality. Regular cleaning and testing restore membrane performance, extend lifespan, and ensure consistent operation.
When should you clean your RO membranes?
- Permeate flow has decreased by more than 10% from the new membrane flow rate or from the rate since the last membrane cleaning.
- Increased differential pressure through the RO system has increased by 15% or more from the feed to concentrate pressure.
- Permeate quality has decreased by ~10% which means there is more salt passage through the membranes.
Our Cleaning & Testing Process
We follow a systematic approach to effectively clean and evaluate your RO membranes:
1. Membrane Inspection & Diagnosis
- Assess system performance metrics (flow rate, rejection rate, pressure drop).
- Identify fouling types (scaling, biofouling, organics, etc.).
2. Custom Cleaning Solution Preparation
- Use specialized chemical formulations tailored to specific fouling issues.
- Maintain optimal pH and temperature levels for effective cleaning.
3. Cleaning Process Execution
- Circulate cleaning solution through the membrane at controlled flow and pressure.
- Soak and rinse cycles to remove stubborn deposits.
4. Performance Testing & Validation
- Conduct permeability and rejection rate tests.
- Compare pre- and post-cleaning performance data.
- Ensure compliance with industry standards.
5. Final Report & Recommendations
- Provide a detailed report on cleaning effectiveness.
- Recommend maintenance schedules for prolonged membrane life.

FAQs
Frequency of cleaning RO membranes depends on factors like quality of feed water, system conditions, and fouling type. Membranes should be cleaned when system performance declines (e.g. reduced flow, increased pressure, decreased salt rejection). Typically membranes require cleaning every 3-12 months, but can vary based on conditions and results.
Typical indicators that reveal that RO membranes need cleaning include: decrease in flow rate, higher feed pressure, increased differential pressure, and reduced water quality or salt rejection rates.
The four types of fouling that affect RO membranes are scaling, biological fouling, organic fouling, and particulate fouling.
Hiring a professional water treatment service is recommended for effective membrane cleaning. Water treatment specialists have the expertise to accurately diagnose fouling, select the right cleaning agents, and clean the membranes without causing damage.
