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.
Features
- Complies with USDA & FDA regulations (paragraph 21
CFR173.5) for potable water applications.*
- Uniform particle size, low pressure drop.
- Superior physical stability.
- Low color throw (APHA No. 50 Max. as shipped).
* For potable water applications, the resin must be properly
pre-treated, usually by multiple exhaustion and regeneration cycles, to insure
compliance with extractable levels.
