Product Description
ASD-002 Large Pore Anion Exchange Resin for Wastewater Nitrate Polishing
Product Information
ASD-002 is a large pore strong basic anion exchange resin engineered for polishing applications where treated effluent must meet strict nitrate and nitrite discharge criteria. With a macroporous structure, 99.8% purity and total exchange capacity of at least 2.6 mmol/g, the resin delivers stable anion removal performance in demanding wastewater environments.
Secondary and tertiary effluent often contains residual organic matter that rapidly fouls conventional gel resins. The large pore network of ASD-002 provides outstanding resistance to organic fouling, maintaining exchange capacity through hundreds of cycles. Nitrate and nitrite are selectively removed in the presence of sulfate, chloride and bicarbonate, and the exhausted resin is economically regenerated with sodium chloride brine, minimizing chemical consumption and waste generation.
Key Features
- Macroporous structure with strong resistance to organic fouling
- Selective nitrate and nitrite removal from complex effluent
- 99.8% purity ensuring stable exchange kinetics
- Regenerable with low-cost sodium chloride brine
- High mechanical strength for long-term column service
- ISO9001:2015 certified quality management

Frequently Asked Questions
Q1: Why choose ASD-002 instead of a conventional gel anion resin for wastewater?
Wastewater effluent typically contains organic matter that fouls gel-type resins quickly. ASD-002 features a large pore structure that resists organic fouling, providing longer service life and more stable nitrate removal in tertiary polishing service.
Q2: What is the recommended regeneration method?
Sodium chloride brine regeneration is recommended for ASD-002. Our technical team can supply the recommended brine concentration, flow rate and contact time based on your feed water analysis.
Q3: Can ASD-002 handle fluctuating nitrate loads?
Yes. The resin bed provides a buffer against load fluctuation. For highly variable influent, we recommend proper bed sizing and, where needed, a lead-lag vessel configuration. Contact us for engineering support.
