About this Product:
The 201×4 (711) is a high-capacity, gelular, Type I strong base anion exchange resin. Its shock-resistant and durable bead form is supplied in either chloride or hydroxide form.
Designed for superior performance, this resin is ideal for all deionization and chemical processing applications. It excels in regenerable mixed bed systems, providing fast kinetics that enable the effective removal of both strong and weak acid anions to achieve exceptionally low residual levels.
Application
The 201×4 (711) resin is a versatile solution with a wide range of applications, including:
- Water Purification: Essential for the production of both pure water and high-purity water, meeting the strict standards of various industries.
- Food & Beverage: Instrumental in the decolorization of sugar solutions, improving the quality and appearance of the final product.
- Environmental Remediation: Used for wastewater treatment to remove harmful anions and pollutants.
- Specialty Extractions: Employed in the extraction of biochemical products and the separation of radioelements.
