Softening Resin ProSoft™ High Porosity
ProSoft High Porosity is the most chemically resistant softening resin we offer. It is manufactured for minimal pressure drops and where high iron content requires constant bed cleaning with solvents. ProSoft High Porosity is also a favorite in chemical processing applications.
ER10009 Pressure Drop Graph
PRESSURE DROP — The graph above shows the expected pressure loss per foot of bed depth as a function of flow rate at various temperatures.
ER10009 Backwash Graph
BACKWASH — The graph above shows the expansion characteristics as a function of flow rate at various temperatures.
ER10009 Softening Capacity Graph
SOFTENING CAPACITY — Capacity is based on 2:1 Ca:Mg ratio, 500 ppm TDS as CaCO3, 0.2% hardness in the salt, and 10% brine concentration applied co-currently through the resin over 30 minutes. No engineering downgrade has been applied.
ProSoft High Porosity (Hydrogen Form) can be used as the cation component in demineralization configurations where a hydrogen form cation resin is coupled with a hydroxide form anion resin. ER10010 is ideal for high flow rate polishers and where high resistance to mechanical, thermal, and oxidative stresses is required.
ER10009 Operating Capacity Graph
OPERATING CAPACITY — Capacity is based on 500 ppm of stated salt (as CaCO3) with 0% alkalinity, 36 inch bed depth, flow rate of 2 to 4 gpm per cu.ft., and a minimum of 30 minutes chemical injection time. Sulfuric acid concentration must be stepwise when calcium concentration exceeds 20% of total cations. No engineering downgrade has been applied.
ProSoft High Porosity is ideally suited for radwaste applications. The high crosslinking content gives it improved resistance to chemical damage caused by ionizing radiation. Structural integrity is maintained up to approximately 1 x 109 rads exposure.
