D201 Macroporous Strong Base Anion Exchange Resin for Ultrapure Water & Condensate Polishing

This product exhibits performance comparable to the 201 × 7 Strongly Basic Styrene Type I Anion Exchange Resin, demonstrating strong basicity. However, due to its macroporous structure, it possesses superior physical and chemical stability, with high resistance to permeation stress, abrasion, and contamination. It can exchange and adsorb larger ions and molecules. This product can be used in non-aqueous media and is commonly employed as a solid strong base catalyst.

Deep desalination of high‑salinity process water

D201 macroporous Type‑I strong‑base anion exchange resin achieves deep desalination for high‑TDS process water in chemical and biotech facilities. Matched with macroporous strong‑acid cation resin, it removes nitrate, perchlorate, sulfate and organic acid radicals. Its rigid macroreticular skeleton resists osmotic shocks from salinity variation, maintaining bead integrity and stable exchange capacity over repeated service‑regeneration cycles, stabilizing effluent conductivity for stringent downstream process‑water requirements.

Organic contaminant removal from fermentation broth

With open macroporous channels, D201 captures high‑molecular organics, pigments and fermentation by‑products from antibiotic broth and amino‑acid mother liquor. Unlike gel‑type resins vulnerable to organic fouling, it resists pore clogging and enables thorough contaminant elution during alkali regeneration. It reduces feed liquid chroma and organic load, minimizing impurity interference and elevating final product purity for biopharmaceutical production.

Waste brine resource recovery

For waste brine from electroplating and hydrometallurgy, D201 selectively strips hazardous anions and soluble organics. Purified brine can be recycled to production lines instead of direct discharge. The resin tolerates high‑salinity conditions without severe swelling‑shrinking damage, cutting freshwater consumption and brine disposal costs to realize brine circular reuse.

Fine purification for circulating cooling water

Deployed in circulating cooling loops of power and petrochemical plants, D201 eliminates excess alkalinity, silicate, phosphate and soluble organic foulants. It mitigates water scaling and cuts nutrient sources for microbes. Good mechanical abrasion resistance fits high‑flow operating conditions. Periodic regeneration restores resin performance, reducing scale‑inhibitor chemical dosage and secondary pollution.

Impurity scavenging for non‑aqueous organic systems

D201 works as purification medium for non‑aqueous organic phases. Its stable cross‑linked macroporous matrix tolerates organic solvents and removes trace acidic and anionic impurities from organic feedstock. It avoids introducing soluble alkali residues as seen with liquid alkali neutralizers; resin‑liquid separation is realized via simple filtration, simplifying post‑treatment and lowering waste‑salt by‑products in fine‑chemical synthesis.
