Further info:

A recent development in the structure of resins is the availability of the uniform particle sized (UPS) resins. Resin manufacturing processes previously made resin beads from small to large in a Gaussian distribution pattern (bell-shaped curve). Today, several manufacturers have perfected manufacturing processes that allow the resin beads to form in essentially one particle size. This produces several unique operating characteristics for a resin and allows manufacturers to provide resins better suited to a given application. In general, regarding demineralization and softening applications, UPS resins will rinse down using less water, backwash.

with less water use and have lower pressure drops for a given bed depth. However, unless the system is closely monitored and controlled, these advantages can go unnoticed and, therefore, may not be properly utilized. Where systems designed for the home or commercial marketplace may not have the controls or monitoring devices needed to take full advantage of UPS resins, industrial systems should be constructed with the controls and monitoring systems that allow users to take advantage of such resins.
