Backwash Expansion Data

See the official PDF for exact tabulated values of expansion (percent) versus flow rate (gpm/sq.ft.) at different temperatures.

Pressure Loss Data

Organic Removal

ResinTech WBMP-OH can remove organic acid anions and is regenerated with sodium hydroxide. It can be used to reduce organic fouling of strong base anion resins in demineralization applications. The feedwater must be acidic or the resin preconverted to the acid sulfate or acid chloride form.

Demineralizer Use

WBMP-OH can be used in two-bed systems after a strong acid cation unit for applications where complete removal of silica and carbon dioxide is not required. It can also precede a strong base anion unit to remove strong acids, leaving silica and carbon dioxide for the strong base resin. Regeneration is effective with modest caustic dosages.
