Each water treatment system is unique, and so are the challenges you face in keeping your systems running at peak efficiency. The impacts of a damaged or poorly operating system can include operational downtime and additional costs for:
System optimization services (SOS) puts our global team of highly skilled, experienced scientists and technicians at your disposal. For a nominal fee, we’ll conduct an assessment using state-ofthe-art equipment and methods to identify critical issues affecting your ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO), and/or ion exchange (IX) systems. These services can lighten the burden of system startup and staff training, as well as assist with troubleshooting, ongoing operation, and maintenance.
We offer testing, evaluation, and troubleshooting of membrane elements and modules in reverse osmosis (RO), nanofiltration (NF), and ultrafiltration (UF) systems. Our battery of tests includes both nondestructive and destructive testing modalities.
Nondestructive testing is generally noninvasive and can include:
Destructive testing is more invasive and can include:
We offer testing and evaluation of ion exchange resins and adsorbents to determine the performance and condition of your current system operation and, if needed, help troubleshoot and identify the root cause for challenges. We can also retest resins that have been warehoused beyond their recommended storage period.
IX resins testing includes the following tests:
This test determines the physical integrity of the beads and if there are contaminants or fouling on the resin surface.
This test uses a light-blocking device to show bead harmonic-mean size, uniformity coefficient, and percent through or retained on standard screen sizes.
This test measures the total number of ion exchange sites per volume of resin after regeneration in the lab and compares the performance of a sample to a new resin to show the sample’s operating capacity.
This test measures the number of ion exchange sites in the regenerated (H+ or OH- ) form to help determine the efficiency of regeneration (if the sample is regenerated) or the extent of exhaustion (if the sample is not regenerated/exhausted).
This test measures the inherent moisture content of the resin. Elevated water content indicates degradation of the polymer chain, while depressed water content typically results from accumulation of foulants on the beads.
This test measures the degree of fouling (organic or inorganic) accumulation on the anion resin, with different analytical methods.
This test measures the strong base (quaternary amine) sites on an anion resin. Salt-splitting sites are necessary to remove weak acid species such as bicarbonate and silica. A reduction in SSC typically indicates an increase in weak base capacity.
This test measures resin kinetics (a resin’s ability to quickly remove ions from solution). As resins age, the rate of exchange may not be fast enough to remove all ions before flow reaches the bottom of the bed, thus exhibiting poor operating performance while maintaining a high total exchange capacity.
This test determines if the resin would benefit from cleaning to remove organics, iron, silica, or other substances. After cleaning, retesting of the resin evaluates the degree of performance recovery.
This test evaluates the resin for osmotic stability by repeated cycles through exhaustion and regeneration using concentrated reagents. The parameter measured to detect the attrition resistance is designated as percent fragmented beads, which is an indication of the resistance of the beads to fragmentation and cracking.
We can conduct a complete water analysis and provide you with a specific breakdown and balance of:
Once the recommended tests are complete, our technical experts will analyze the data and suggest corrective actions that address the root cause of system underperformance, with the goal of maximizing your overall operation.
