Overview
The 400,000 Equivalent Composite Carbon Source is a specialized chemical formulation designed to optimize biological denitrification in wastewater treatment processes. It serves as an alternative to conventional carbon sources, offering higher efficiency and lower operational costs. The '400,000 equivalent' denotes its high carbon content, measured in terms of chemical oxygen demand (COD), which ensures rapid microbial uptake and nitrogen removal. Developed for industrial and municipal applications, this product is favored for its stability and ease of integration into existing treatment systems. Its composite nature often includes a blend of organic acids, sugars, and other biodegradable compounds, tailored to meet stringent environmental standards.
Physical and Chemical Properties
This composite carbon source typically appears as a viscous liquid, ranging from amber to dark brown, with a density slightly higher than water. It is fully soluble, ensuring uniform distribution in treatment tanks. The formulation is engineered for rapid biodegradability, minimizing residual sludge formation. Key chemical properties include a high COD value (typically 400,000 mg/L or higher), which directly correlates with its denitrification efficiency. Unlike methanol, it poses lower flammability risks and reduces the need for strict safety protocols during storage and handling.
Main Applications
The primary use of this carbon source is in wastewater treatment plants, particularly for enhancing denitrification in anoxic or anaerobic conditions. It accelerates the growth of denitrifying bacteria, converting nitrates into nitrogen gas. Industries such as textiles, pharmaceuticals, and food processing rely on it to meet effluent discharge regulations. It is also employed in aquaculture and landfill leachate treatment, where controlled carbon supplementation is critical. Municipalities use it to upgrade aging infrastructure without costly retrofits, leveraging its compatibility with diverse microbial communities.
Safety and Storage
While non-flammable, the composite carbon source requires standard chemical handling precautions. Storage in HDPE or stainless steel containers is recommended to prevent degradation. Exposure to extreme temperatures should be avoided to maintain product consistency. Spills should be contained with absorbent materials and disposed of according to local regulations. Safety data sheets (SDS) provided by manufacturers outline first-aid measures, though toxicity is generally low compared to traditional carbon sources like methanol.
B2B Procurement Guide
Procurement teams should prioritize suppliers with ISO 14001 certification to ensure environmental compliance. Bulk purchases (e.g., tanker loads) often reduce costs by 10–20%. Key evaluation metrics include COD consistency, microbial stimulation efficiency, and post-treatment sludge volume. Contracts should specify delivery terms, as some formulations may require temperature-controlled transport. Pilot testing is advised to confirm compatibility with site-specific microbial populations and treatment kinetics.
