Commissioning and Limits of Use

AMBERLITE PWA15 is suitable for use in potable water applications after an initial commissioning rinse of 10 BV of water at ambient temperature. The operating capacity depends on operating and feed water conditions.

Regulatory

AMBERLITE PWA15 resin is certified to ANSI / NSF Standard 61 for drinking water components. Resin products are manufactured in ISO 9001 certified facilities.

Hydraulic Characteristics

Pressure drop and bed expansion data are provided in graphical form as a function of flow rate and water temperature. These data are valid at the start of the service run with clean water and a correctly classified bed.
