Softening Resin
swtwater.com ProSoft™ Premium
ProSoft Premium is the best value for an all-around, hard working, softening resin. It is primarily used on the types of chlorinated waters associated with municipal water treatment. Its full 8% crosslinking makes ProSoft Premium more resistant to chlorine attack and the vigorous backwashes of commercial applications and turbulators.

APPLICATIONS
Softening
ER10002 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.
 
Demineralization
ProSoft Premium (Hydrogen Form) can be used as the cation component in separate bed and mixed bed demineralization applications where a hydrogen form cation resin is coupled with a hydroxide form anion resin. Regeneration is accomplished with stepwise sulfuric acid or with hydrochloric acid.applied.
 
ER10002 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.
 
Iron Removal
ProSoft Premium has a good capacity for ferrous iron. Iron content in the feedwater should not be more than 1 mg/L Fe per each 17 mg/L of hardness.
 
Amonia Removal
ProSoft Premium is slightly selective for ammonia compared to sodium, but hardness is much more preferred. Ammonia is not ionized at pH above 9 and is not well removed when the pH is significantly alkaline.
