PA201 Detailed Introduction
Product Description
Pure PA201 is a high capacity, shock resistant, macroporous, Type II, strongly basic anion exchange resin supplied in the chloride or hydroxide form as moist, tough, uniform, spherical beads.
Applications
Pure PA201 has a high operating capacity, especially on high-FMA feedwaters, as well as a high reversible sorptive capacity for complex organic materials, such as the fulvic and humic acids which occur in many surface water supplies.
It is recommended for use in waters with low silica loads. For high silica waters, a type I anion resin such as Pure PA200 is recommended.
