Shallow Shell Technology Resins
                              
 
The Purolite SST family of high efficiency ion exchange resins is based on shallow shell technology. Simply stated, the shorter the diffusion path, the more rapid the ion exchange occurs. This is particularly important during regeneration. Reducing the depth of penetration required to cleanse the resin allows for a more complete regeneration and provides a higher, more efficient utilization of the regenerant. The result is a group of resins with unsurpassed regenerant efficiency, lower leakage, and reduced rinse water requirements. When compared to conventional softening resins, regenerant reductions of 20 to 40% of regenerant is possi­ble without sacrificing capacity or increasing leakages.
 
Under a microscope, PUROLITE SST resins look different than other resins. That’s because the resins have inert centers. Only the outer shell is functional­ized. By shortening the diffusion path through the use of shallow shell technology, each resin bead presents the same depth of functionality which leads to more efficient use of regenerant and therefore, better regeneration. This in turn leads to higher capacities, lower leakages and better handling of iron.
