AQUARIUM RO DI 1.5 lb BAG COLOR CHANGE DI RESIN

Our resin refill bags are filled with brand new never recycled color change deionization resin by resintech. Color changes from blue to gold as DI begins to exhaust. Dont be fooled by other lower priced resins. Our resin is brand new and is TRUE deionization resin that will not separate when used. This gaurantees maximum exposure from water to resin which results in true zero conductive product water. Your purchase will include 1.5 lbs of resin which is just over one refill.

RESINTECH MBD-30 is a self indicating mixed bed resin. It is a mix of nuclear grade hydrogen and hydroxide form resins. The anion resin is a Type I strongly basic gel resin with an indicator dye that changes from blue to colorless as the resin exhausts. The cation component is a strong acid sulfonated polystyrene gel type cation exchange resin. During exhaustion, as the indicator dye changes color, the appearance of the mixed bed changes from a blue color to a very light brown color. Many manufacturing processes require high purity water for washing, rinsing and test purposes. Not all processes requiring demineralized water need the ultimate quality. However, they may require multi-megohm resistivity water.
RESINTECH MBD-30 is designed to provide demineralized water with a resistivity in excess of 10 megohm. It is specially intended for use in
cartridge applications with clear (see through) housings. Such systems are typically designed without meters and rely on the changing color of
the mixed bed resin to indicate exhaustion. In typical operation there is a “safety line” at the exit end of the cartridge, and when the color change
reaches that level, the cartridge is considered exhausted and exchanged for a fresh cartridge. The actual quality that is obtained depends on the
manner in which the cartridge is configured.
A constant supply of high purity water can be obtained by using two cartridges in series, and allowing the first cartridge to completely change
color. During this operation the second cartridge insures that the water leaving the system is of the highest purity. New cartridges are placed
into the polishing position and the remaining cartridge is put into the “roughing” position. This insures complete utilization of all the exchange
capacity, which lowers operating costs while increasing average quality.
RESINTECH MBD-30 is manufactured from nuclear grades of gel Type I strongly basic anion resins and strongly acidic sulfonated polystyrene gel type cation exchange resins.
