Reverse Osmosis Data Analysis
Data collection is critical for monitoring the performance of the membrane system. Without it, there will be no idea if the system is fouling, suffering from scale formation, or if the membranes are deteriorating. When operating data is recorded, it should be compared to previously established alert and alarm levels. These levels should be associated with well-defined response procedures corresponding to the potential problem.
The permeate (product water) flow of the RO system is related to water temperature, net driving pressure (NDP) and, conductivity. Permeate flow should therefore be standardized for the effects of these variables to allow better monitoring of how well water is permeating through the membranes. This standardized flow is referred to as “normalized”. Cleaning after 10-15% decline in the normalized data will maximize the performance and life of your membranes.
Nalco can make recommendations to help you improve your RO system operation. The PermaCare Team can look at your RO operating data, conduct an analysis, and based on the results make recommendations to improve your operation and reduce your operating costs. Recommendations may include:
- Scale and fouling control recommendations
- Cleaning schedule
- RO Recovery Optimization
- System equipment configuration
Contact Nalco to learn more about our data analysis and trending equipment and services, including RO Data Normalization.
