MBD-35
PDF datasheet mirror for MBD-35 (ResinTech). Verify with OEM before design.
Summary
Product identification
- Product Name: MBD-35
- Product Type: MIXED BED
- Manufacturer: ResinTech, Inc.
- Revision: 1.0
ResinTech MBD-35 is a 2:3 volumetric mixture of CG8-H-ID (a dyed hydrogen form cation resin) and SBG1P-OH (a hydroxide form type 1 porous strong base anion resin). The cation component is infused with a permanent pH indicator dye that changes color from royal purple to amber as the resin exhausts. MBD-35 is intended for use in cartridge applications where a color indication of resin exhaustion is desired.

Throughput Capacity
Mixed Bed 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 (2.5µS/cm/ppm as CaCO₃). Different salts may have different contributions to TDS. Capacity is based on the anion component and is for virgin resin. Following the initial exhaustion and regeneration, subsequent cycles will likely be shorter, depending on how skillfully the resins are separated, regenerated, and remixed.
| TDS (ppm as CaCO₃) / Conductivity (µS/cm) | No CO₂ or SiO₂ | 5 ppm CO₂ or SiO₂ | 10 ppm CO₂ or SiO₂ |

| 2/5 | 111,834 | 31,953 | 18,639 |
| 5/12.5 | 44,734 | 22,367 | 14,911 |
| 10/25 | 22,367 | 14,911 | 11,183 |
| 20/50 | 11,183 | 8,947 | 7,456 |
| 50/125 | 4,473 | 4,067 | 3,728 |
| 100/250 | 2,237 | 2,130 | 2,033 |
| 200/500 | 1,118 | 1,091 | 1,065 |

Cartridge Use
ResinTech MBD-35 premixed mixed bed is ideal for single use cartridge applications where the longest possible throughput capacity is desired. The cation component of MBD-35 is dyed purple and turns amber in color as the resin exhausts, providing a visual indication of resin life remaining. The ratio of anion to cation resin is optimized to provide balanced exchange of both cations and anions as well as to maximize throughput.
