Strong Base Anion Exchange Resin Delivering High Exchange Capacity for

The SB-AER-201 is a premium Type I strong base anion exchange resin engineered specifically for high-performance industrial water treatment applications. Built on a robust styrene-divinylbenzene copolymer matrix with quaternary ammonium functional groups, this gel-type resin delivers exceptional ion exchange kinetics and superior exchange capacity. It is designed to effectively remove anions including chloride, sulfate, nitrate, and silica from feed water streams, making it an indispensable component in demineralization trains, condensate polishing systems, and ultrapure water production lines.

Manufactured under strict quality control in our ISO 9001 certified facility, SB-AER-201 features a uniform particle size distribution that ensures low pressure drop and high throughput across industrial-scale columns. With a total exchange capacity exceeding 1.35 eq/L and operational stability across the full pH spectrum, this resin consistently outperforms conventional alternatives in terms of regeneration efficiency and long-term durability. Whether deployed in power generation, semiconductor manufacturing, pharmaceutical water systems, or chemical processing, SB-AER-201 provides reliable, cost-effective anion removal that meets the most demanding water quality specifications.

• High Exchange Capacity: Total exchange capacity of ≥ 1.35 eq/L ensures maximum ion loading per regeneration cycle, reducing chemical consumption and operational downtime while increasing throughput efficiency for large-scale water treatment facilities.
• Excellent Ion Removal: Quaternary ammonium functional groups provide robust and selective removal of a broad spectrum of anions including chloride, sulfate, nitrate, bicarbonate, and silica, achieving sub-ppb residual levels in multi-bed polishing configurations.
• Wide pH Operating Range: Stable performance across pH 0-14 enables versatile deployment in acidic process streams, alkaline regeneration cycles, and neutral pH polishing applications without degradation of exchange capacity or bead integrity.
• Superior Mechanical Strength: High whole bead count (≥ 90%) and excellent osmotic shock resistance minimize bead breakage and fines generation during repeated regeneration cycles, extending resin bed service life and reducing replacement frequency.
• Fast Kinetics: Optimized gel-type macroporous structure with uniform particle size distribution (0.315-1.25 mm) enables rapid ion diffusion and exchange, resulting in shorter contact times and higher flow rates in continuous treatment systems.
• Thermal Stability: Rated for continuous operation up to 60°C in hydroxide form and 80°C in chloride form, accommodating elevated temperature process streams without resin degradation or capacity loss.
• Low Rinse Volume: Engineered for efficient regeneration with minimal rinse water requirements, reducing wastewater generation and overall operating costs in demineralization plant operations.

The SB-AER-201 strong base anion exchange resin is specifically engineered for a wide array of industrial water treatment and purification applications. In power generation facilities, it serves as a critical component in mixed-bed demineralization systems for boiler feed water production, where ultralow conductivity and silica levels are mandatory to prevent turbine scaling and corrosion. For the electronics and semiconductor industry, SB-AER-201 is deployed in ultrapure water (UPW) polishing loops to achieve resistivity levels exceeding 18 MΩ·cm required for wafer fabrication and cleaning processes.

In chemical and petrochemical processing, this resin provides reliable removal of organic acids, phenols, and trace anionic contaminants from process condensate and wastewater streams before discharge or reuse. Pharmaceutical and biotechnology facilities utilize SB-AER-201 in water-for-injection (WFI) pretreatment and purification systems where consistent, high-purity water quality is essential for compliance with USP, EP, and JP pharmacopeia standards. Additionally, the resin is well-suited for metal finishing and electroplating operations, where it removes chromates, cyanide complexes, and heavy metal anions from rinse waters to meet stringent environmental discharge regulations.

SB-AER-201 is supplied in 25-liter moisture-sealed polyethylene bags or 1000-liter flexible intermediate bulk containers (supersacks) with moisture-barrier liners to preserve optimal water content during storage and transport. Custom packaging configurations including palletized loads, shrink-wrapped units, and UN-certified containers for hazardous location shipping are available upon request. Each production batch undergoes rigorous quality testing including exchange capacity titration, particle size distribution analysis via laser diffraction, moisture content determination, and whole bead integrity microscopy inspection. A comprehensive certificate of analysis (CoA) documenting all measured parameters is supplied with every shipment. We maintain full batch traceability from raw material receipt through finished product dispatch, and retain samples of each production lot for a minimum of 24 months to support long-term quality investigations and customer audits.
