Purolex PRC107E is a high purity, premium grade, pre-washed, strong acid gel-type cation exchange resin (high purity bead form conventional gel polystyrene sulfonate cation exchange resin), designed especially for potable waters, beverages and other water processing of food.
The resin can also remove dissolved iron, manganese, and suspended materials through the filtering action of the softening bed. In addition, it is a cost-effective product for treating any household water.

The pressure drop (headloss) across a properly classified bed of ion-exchange resin depends on the particle size distribution, bed depth, and void volume of the exchanger; and on the flowrate and viscosity (and hence on the temperature) of the influent solution. Anything affecting any of these parameters, for example the presence of particulate matter filtered out by the bed, abnormal compaction of the resin bed, or the incomplete classification of the resin will have an adverse effect, and result in an increased headloss. Typical values of pressure drop across a bed of Purolex PRC107E are given for a range of operating flow rates in Fig. 1.
During upflow backwash, the resin bed should be expanded in volume by between 50 and 75%, in order to free it from any particulate matter from the influent solution, to clear the bed of bubbles and voids, and to reclassify the resin particles as much as possible, ensuring minimum resistance to flow. Backwash should be commenced gradually to avoid an initial surge with consequent carryover of resin particles. Bed expansion increases with flow rate and decreases with temperature, as shown in Fig. 2, above. Care should always be taken to avoid resin loss by accidental overexpansion of the bed.
