System Optimization Services (SOS)
Dow Water & Process Solutions offers ion exchange resin and membrane element testing services to its customers for a nominal fee. Resins and elements can be tested to determine their suitability for continued operation or to troubleshoot problems in ion exchange, reverse osmosis or nanofiltration systems. In addition to test results, we provide a complete report with a description of the tests performed and the implications of the test results on your operation.

SOS services include:
- RO element and UF module testing
- Membrane and fiber fouling composition
- Membrane and fiber characterization
- Ion exchange resin analysis
- Water analysis
- Complete analysis report
- Comprehensive overall service and support
Ion Exchange (IX) Resin Analyses
Our ion exchange resins and adsorbents testing and evaluation services determine the performance and condition of current system operation and, if needed, can troubleshoot and identify the root cause for challenges. We also can retest resins that have been warehoused beyond their recommended storage period. As with our membrane analyses, Dow experts also interpret the data and provide you a complete report with a description of the tests performed and the implications of the test results on your operation, and suggest ways to enhance your system performance.
Resin testing can include:
- Microscopic Bead Examination (MBE)
- Particle Size Distribution
- Total Exchange Capacity (TEC)
- Total Exchange Capacity as received (TEC as received)
- Water Retention Capacity (WRC)
- Organic and or Inorganic Fouling
- Salt-Splitting Capacity (SSC)
- Mass Transfer Coefficient (MTC)
- Resin Cleaning Tests
- Osmotic Shock and Attrition (OSA)
- Water Analysis
Membrane Testing Services
Dow Water & Process Solutions offers troubleshooting and membrane element and module testing and evaluation services to help diagnose the root cause of system underperformance and maximize your overall operation. Our battery of tests will determine your elements’ or modules’ suitability for continued operation or troubleshoot problems in reverse osmosis (RO), nanofiltration (NF) or ultrafiltration systems (UF). Our experts will then interpret the data and provide a complete report describing the tests performed and the implications of the test results on your operation, and suggest ways to enhance your system performance.
Membrane testing can include:
- Physical inspection
- Performance tests
- Cleaning Recommendations
- Element autopsy and membrane analysis
- Determination of Fouling, Scaling, or Chemical Damage
- Water analysis
