Product Description
PRODUCT INFORMATION
ASD-003 Resin for Iron Removal in Steel Pickling Hydrochloric Acid
ASD-003 is a macroporous weak base anion exchange resin with a polystyrene backbone, specifically formulated to remove iron ions from high concentration hydrochloric acid, and is widely known as a “special resin for hydrochloric acid iron removal.” In steel pickling lines the resin pulls dissolved iron out of the spent acid so the acid can be regenerated and returned to the pickling bath, cutting fresh acid consumption and spent acid disposal.
KEY FEATURES
- Targets dissolved iron ions in high concentration hydrochloric acid with high selectivity.
- High regeneration efficiency using pure water keeps operating cost low and avoids heavy chemical dosing.
- Substantial exchange capacity allows long service cycles between regenerations.
- Robust anti-pollution resistance tolerates the suspended solids and organics typical of pickling liquor.
- Excellent mechanical strength and >90% sphericity after attrition for long media life.
- Enables closed-loop acid regeneration, reducing fresh acid purchase and waste acid discharge.

FAQ
Q: Where is ASD-003 installed in a pickling acid loop?
It is typically placed on a side-stream or full-flow basis before the pickling bath return line, removing iron so the regenerated acid stays within the target iron window.
Q: How is the resin regenerated?
ASD-003 is regenerated with pure water thanks to its high regeneration efficiency, which keeps the operating cost low and avoids the chemical consumption of conventional brine processes.
Q: Can I get a free sample for testing?
Yes, a free sample is available and only the courier cost is covered by the buyer. Share your HCl concentration, iron content and flow rate for a sizing recommendation.
Q: What is the delivery time?
Stock grades ship in 3-7 working days; customized packaging or container orders take 15-25 days after confirmation.
Q: Do you provide quality certificates?
Yes, all products meet international quality standards and pass ISO 9001:2015 procedures. We can provide certificates and test reports for your reference.
