Shallow Shell Technology Resins
                              

 
The Purolite SST family of high efficiency ion exchange resins is based on Shallow Shell Technology. Under a microscope, Purolite SST resins look very different from other resins. That’s because the resins have inert centers. Only the outer shell is functional­ized which shorten the ion exchange diffusion path. This leads to more efficient ion exchange and regeneration, providing higher capacities, lower leakages and better handling of iron and organic foulants.

In todays increasing need for performance and lower operating costs Purolite SST enables a more complete regeneration and provides a higher, more efficient utilization of the regenerant. The result is a family of resins with unsurpassed regenerant efficiency, lower leakage, and reduced rinse water requirements. When compared to conventional softening or demineralization resins, regenerant cost reductions of 20 to 50% is often possi­ble without sacrificing capacity or increasing leakages.
