Softening Resin
swtwater.com ProSoft™ Heavy Duty
ProSoft Heavy Duty is just that. Manufactured in special runs to provide one of the toughest softening resins around. With a 10% crosslink and 35,000 grain capacity at 15 lbs of salt, ProSoft Heavy Duty is perfect for industrial applications involving rigorous backwashing or high chlorine levels.

APPLICATIONS
Softening
ER10006 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 Heavy Duty (Hydrogen Form) can be used as the cation component in a variety of demineralization configurations where a hydrogen form cation resin is coupled with a hydroxide form anion resin. The high density of ER10007 provides ideal separation in polishing mixed beds. ProSoft Heavy Duty (Hydrogen Form) has higher total capacity and lower chemical efficiency compared to ProSoft Premium (Hydrogen Form).
 
ER10006 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.
 
High Temperature Use
ProSoft Heavy Duty is suitable for operation at temperatures as high as 280°F. At temperatures above 212°F, dissolved oxygen in the feedwater is a powerful oxidant and can chemically damage the resin. Oxygen levels in the feed should be reduced to less than 0.05 ppm to ensure a reasonable service life of the resin.
