DI Refillable color changing cartridge. The color changes as DI is exhausting. The color changes from a green/blue to a dull rust color as it exhausts.This helps you to visually keep track of the quality of your water. Our DI cartridge is the best available for this 10 inch size filter housing.
This single DI Cartridge is made from MBD-30 is a self indicating mixed bed resin. It is a mixture 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 greenish blue to rusty brown 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 green color to a 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. 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 car
