Overview
High Concentration COD Degradation Agent is a chemically engineered solution designed to break down complex organic pollutants in industrial wastewater. It targets high Chemical Oxygen Demand (COD) levels, a critical parameter in wastewater discharge compliance. The agent typically contains advanced oxidizers or biocatalysts to accelerate organic matter decomposition. This product is indispensable for industries with heavy organic loads, such as dyeing, pharmaceutical manufacturing, and food processing. Its formulation ensures minimal secondary pollution, aligning with global environmental regulations. Unlike conventional treatments, it achieves faster results with lower dosing requirements.
Physical and Chemical Properties
The agent is usually supplied as a liquid with a mild odor, optimized for easy dilution and integration into existing wastewater systems. Its density ranges from 1.1 to 1.3 g/cm³, ensuring effective mixing without sedimentation. The solution is stable across a pH range of 3–11, making it versatile for diverse wastewater conditions. Key chemical properties include high redox potential and selective reactivity with organic compounds. It minimizes sludge generation compared to traditional coagulants, reducing disposal costs. Solubility in water is instantaneous, facilitating automated dosing systems in large-scale operations.
Main Applications
Primary applications include textile dyeing wastewater, where it degrades azo dyes and auxiliaries, and pharmaceutical effluent treatment, breaking down antibiotic residues. Petrochemical plants use it for hydrocarbon-laden wastewater, while pulp/paper mills employ it to address lignin derivatives. The agent is also effective in landfill leachate treatment and municipal wastewater plants during peak organic loads. Its rapid action (typically 30–90 minutes) allows for compact reactor designs, saving space and infrastructure costs. Some formulations are compatible with biological treatment systems, enhancing overall plant efficiency.
Safety and Storage
While non-flammable, the agent requires handling with nitrile gloves and goggles due to potential skin/eye irritation. Storage tanks should be corrosion-resistant (e.g., polyethylene or fiberglass) and equipped with ventilation. Shelf life is typically 12–24 months when stored below 30°C. Spill management involves neutralization with sodium bicarbonate and containment to prevent environmental release. Transport regulations classify it as a Class 8 (corrosive) substance in some jurisdictions, requiring proper labeling. Always consult Safety Data Sheets (SDS) from suppliers for specific guidelines.
B2B Procurement Guide
Procure from suppliers with proven track records in industrial wastewater chemicals. Request third-party test reports for COD removal efficiency (e.g., ≥85% reduction at 5000 mg/L COD). Bulk purchases (20+ tons) often attract 10–15% discounts. Consider regional logistics: some formulations may require temperature-controlled transport. For OEM partnerships, negotiate customized concentrations or blended products targeting specific pollutants. Payment terms like LC (Letter of Credit) are common for international transactions. Always validate supplier ISO 9001/14001 certifications and request pilot-scale testing before large orders.
