MBD-15

Summary

Product identification

• Product Name: MBD-15
• Product Type: MIXED BED
• Product Line: ResinTech
• Revision: 1.1
• Description: A mixture of a dark colored hydrogen form cation resin and a hydroxide form type 1 strong base anion resin. Intended for use in all mixed bed deionization applications that require high resistivity and high throughput capacity. The component resins are chosen to separate easily for regeneration.

Applications

• Portable Exchange Deionization (PEDI)
• In-Place Regeneration
• Cartridge Applications

Backwash Expansion

Backwash expansion is shown graphically with percent of expansion versus flow rate (gpm/sq.ft.) at various temperatures (40°F, 60°F, 80°F, 100°F).

Pressure Loss

Pressure loss is shown graphically with psi/ft. of Resin versus flow rate (gpm/sq.ft.) at various temperatures (40°F, 60°F, 80°F, 100°F).

Throughput Capacity (Gal/cu. ft.)

Throughput capacity is listed in a table showing gallons per cubic foot versus Total Dissolved Solids (TDS) in ppm as CaCO₃ (or equivalent for specified ions). The table includes values for different feed water conditions:

• No CO₂ or SiO₂
• 5 ppm CO₂ or SiO₂
• 10 ppm CO₂ or SiO₂

The TDS values are presented in two formats: "2/5", "5/12.5", "10/25", "20/50", "50/125", "100/250", "200/500", "500/1250", "1,000/2500".

Note: Mixed Bed throughput capacity is to a 1 µS/cm endpoint. TDS is based on NaCl. Capacity is based on virgin resin.

Packaging Options
