MBD-20

Summary

Product Identification

• Product Name: MBD-20
• Product Type: MIXED BED
• Description: HIGH-CAPACITY MIXED BED, TYPE II ANION, POLYSTYRENIC GEL, H / OH FORM

ResinTech MBD-20 is a 4:5 volumetric mixture of CG8-H-BL (a dark-colored hydrogen form cation resin) and SBG2-OH (a hydroxide form type 2 strong base anion resin).

Applications

• Cartridge Applications
• Portable Exchange Deionization (PEDI)

Operating Limits

• Maximum continuous temperature: 95°F (This is stated in the "Suggested Operating Conditions" section for cartridge use, while the "Physical Form" section lists a Temp Limit of 250°F (121°C) for the resin itself.)
• Operating pH range: 2 to 12 SU
• Maximum pressure loss: 25 psi

Feed Water

• Inlet conductivity: Neutral pH waters, run to a 1 µS/cm endpoint.
• TDS: Based on NaCl (2.5 µS/cm/ppm as CaCO₃). Different salts may have different contributions to TDS.

Product Water

• Endpoint Conductivity: 1 µS/cm for throughput capacity calculations.

Throughput Capacity

Throughput capacity is based on the stated inlet conductivity of neutral pH waters and run to a 1 µS/cm endpoint. TDS is based on NaCl (2.5 µS/cm/ppm as CaCO₃). Capacity is based on the anion component and is for virgin resin. Subsequent cycles after initial exhaustion and regeneration will likely be shorter.

Note: The table above lists capacity in Gal/cu. ft. The first number in the "TDS" column is ppm CO₂, and the second is ppm SiO₂. The table appears to be cut off or incomplete.

Backwash Expansion Graph:

• Shows percent expansion vs. gpm/sq.ft. at various temperatures (40°F to 100°F). The graph indicates that expansion is roughly 0% at 0 gpm/sq.ft. and reaches approximately 100% at around 3.0 gpm/sq.ft. at 40°F, with lower expansion at higher temperatures for the same flow rate.

Pressure Loss Graph:

• Shows psi/ft. of Resin vs. gpm/sq.ft. at various temperatures (40°F to 100°F). The graph indicates pressure loss increases with flow rate and temperature. At 3.0 gpm/sq.ft. and 100°F, the pressure loss is approximately 20 psi/ft. of resin.
