ResinTech - Model MBD-15 -Mixed Bed Resins
ResinTech MBD-15 is a one-to-one equivalent mixture of CG8-H-BL (a hydrogen form strong acid cation resin) and SBG1P-OH (a hydroxide form type 1 porous strong base anion resin). MBD-15 utilizes a dark colored cation resin and a light colored anion resin and is designed to produce very high water quality and to separate easily for regeneration. ResinTech MBD-15 is intended for use in all mixed bed deionization applications that require high resistivity and high capacity. MBD-15 is particularly well suited for portable exchange and other polishing applications. MBD-15 is supplied ready to use with the cation component in the hydrogen form and the anion component in the hydroxide form. Available in grades.

High Total Capacity
Cation and anion mixture provides high capacity for “in place” mixed bed installations
Ease of Separation
Density and color difference between cation and anion components results in good backwash separation during regeneration
Superior Organic Fouling Resistance
Highly porous anion component minimizes organic fouling
Ideal for Portable Exchange Di Systems
All resin parameters are optimized for use in portable exchange DI systems where the resin is regenerated at a central facility
Complies with us FDA Regulations
Conforms to paragraph 21CFR173.25 of the Food Additives Regulations of the US FDA.
In Place Regeneration
ResinTech MBD-15 is ideal for in place regenerated mixed beds, especially if they are set up for the 60/40 anion to cation ratio that is optimum for most mixed bed polishers. The cation component, CG8-H-BL, has optimized bead size to separate cleanly from the anion component, SBG1P-OH.
Portable Exchange Deionization (PEDI)
ResinTech MBD-15 can be used in PEDI applications to remove bulk TDS from raw waters or to remove trace levels of TDS following reverse osmosis or other desalination processes. The mixed resin can be separated into its components, CG8-H-BL and SBG1P-OH, for regeneration, and reused hundreds or thousands of times. The cation component, CG8-H-BL, is dark in color and provides optimized color difference from SBG1P-OH. This color difference is very helpful to verify resin separation during backwash.
