DESCRIPTION |
Nitrate-selective anion exchange resins are strong base anion (SBA) exchange media specifically designed to preferentially remove nitrate ions (NO₃⁻) from water. Their key feature is a specialty functional group that gives them a higher affinity for nitrate over other common anions like sulfate (SO₄²⁻) and chloride (Cl⁻), which is a significant advantage over standard anion resins. They are often based on a macroporous polystyrene-divinylbenzene matrix.
Drinking Water Treatment: Primary application for removing nitrate from groundwater and municipal water supplies to meet health standards.
Municipal Wastewater Treatment: Used in advanced treatment systems for nitrate removal to meet discharge regulations.
Industrial Wastewater Treatment: Effective for treating nitrate-contaminated wastewater from chemical, fertilizer, and metal processing industries.
Agricultural Runoff Treatment: Deployed in treatment systems to address nitrate pollution from farm drainage.
Aquaculture and Aquarium Systems: Maintains low nitrate levels in recirculating water systems.
Note: These are typical parameters. Always consult manufacturer specifications for precise values.
1. Operating Conditions
Service Flow Rate: 5-15 BV/h (bed volumes per hour)
Operating Temperature: 5-40°C
pH Range: 6.0-8.5 (optimal performance range)
Maximum Operating Pressure: 3-5 bar
2. Regeneration Parameters
Regenerant: Sodium chloride (NaCl)
Concentration: 8-12% brine solution
Dosage: 120-200 g NaCl/L resin
Contact Time: 30-60 minutes
Flow Rate: 2-4 BV/h
3. Rinsing Requirements
Fast Rinse Flow Rate: 10-15 BV/h
Rinse Volume: 2-3 bed volumes
Rinse Endpoint: When effluent chloride matches influent levels
4. Performance Characteristics
Total Exchange Capacity: ≥1.0 eq/L
Nitrate Selectivity Coefficient: >4 (relative to chloride)
Moisture Content: 50-60%
Particle Size Range: 0.3-1.2 mm
5. Important Considerations
Pre-filtration recommended for waters with suspended solids >5 mg/L
Performance affected by high sulfate concentrations (>100 mg/L)
Regular backwashing recommended to maintain bed porosity
Avoid exposure to strong oxidizing agents
ADVANTAGES |
High Adsorption Capacity: The macroporous structure provides a large specific surface area (typically ≥480 m²/g), enabling efficient adsorption of target molecules.
Good Selectivity: Its non-polar characteristics make it highly selective for adsorbing non-polar or weakly polar substances, reducing interference from impurities.
Stable Physical and Chemical Properties: Exhibits strong resistance to acid, alkali, and organic solvents, with a long service life.
Regenerability: Can be easily regenerated using organic solvents (e.g., ethanol, acetone), lowering long-term operational costs.
Environmentally Friendly: Does not release ionic pollutants during use, making it an environmentally friendly separation material.
