Description
ASD-002 Strong Base Anion Exchange Resin for Aquaculture Nitrite Control
Product Information

ASD-002 is a macroporous strong basic anion exchange resin with quaternary ammonium functional groups (-N+(CH3CH2)3) and 99.8% purity. Its large pore network and high mechanical strength make it an ideal media for removing nitrite from recirculating water in aquaculture operations, where water quality directly determines fish survival and growth performance.

Nitrite accumulation is one of the most common water quality failures in recirculating aquaculture systems, hatcheries and intensive ponds. ASD-002 selectively exchanges nitrite ions even in water containing chloride, sulfate and bicarbonate, protecting fish and shrimp from nitrite toxicity without the use of chemical additives. Routine sodium chloride regeneration restores capacity quickly, allowing stable, long-term water reuse at lower operating cost.

Key Features
  • Selective nitrite removal in saline and mixed-ion culture water
  • 99.8% purity macroporous beads with high attrition resistance
  • Rapid regeneration with sodium chloride brine
  • Stable performance across wide pH and temperature ranges
  • Reduces water exchange demand and supports water reuse
  • ISO9001:2015 certified manufacturing process

Frequently Asked Questions
Q1: How does ASD-002 protect fish from nitrite?
ASD-002 removes nitrite ions from the culture water through selective ion exchange, keeping nitrite concentration below the toxic threshold for the farmed species. This prevents nitrite-induced stress and methemoglobinemia commonly seen in intensive aquaculture.
Q2: How often does the resin need regeneration in an RAS?
Regeneration frequency depends on stocking density, feeding rate and water exchange volume. We will help you calculate bed volume and regeneration intervals based on your system parameters.
Q3: Do you provide free samples for trial?
Yes. We provide free resin samples for water treatment trials; you only need to cover the courier cost. Contact us with your application details and we will recommend the right grade.
