PRESSURE DROP - The graph above
shows the expected pressure loss per foot of bed depth as a function of flow
rate at various temperatures.Features
- Complies with FDA regulations (paragraph 21 CFR173.5) for
potable water applications.*
- Uniform particle size, low pressure drop.
- Superior, physical stability.
- Organic fouling resistance high operating capacity.
* For potable water applications, the resin must be properly
pre-treated, usually by multiple exhaustion and regeneration cycles, to insure
compliance with extractable levels.
