Lasen-904 COD Remover is a highly efficient, novel COD-degrading agent independently developed by the engineering team at Lanshen Company. It is a composite formulation consisting of multiple inorganic salts and various additives, appearing as a white powder with a slight yellowish tint. Integrating adsorption, oxidation, and other treatment technologies, it rapidly and effectively decomposes organic pollutants in water, achieving a COD removal efficiency of over 95%. This product is specifically designed to address wastewater with excessive COD levels that fail to meet discharge standards, offering remarkable COD reduction performance and ensuring consistent compliance with national effluent regulations.Lasen-904 COD Remover demonstrates strong adaptability to variations in raw water temperature, turbidity, alkalinity, and organic content. Since its development and market launch, it has received unanimous acclaim from users across various industries and environmental protection companies.The Lasen-904 series includes four variants—General Purpose, High-Efficiency, Professional, and Ultra-Potent—allowing selection of the optimal type based on specific water quality characteristics and industry requirements.
Product Introduction
COD removal agents are specialized chemical reagents designed to reduce the chemical oxygen demand (COD) in water. Chemical Oxygen Demand (COD) refers to the amount of a strong oxidizing agent consumed when treating a water sample under specific conditions. It serves as an indicator of the concentration of reducing substances—primarily organic matter—in water. A higher COD value indicates more severe organic pollution in the water body. COD removal agents work by chemically reacting with organic and other reducing substances in the water, breaking them down or converting them into other compounds, thereby lowering the COD concentration and improving water quality.
Product Advantages
Fast reaction speed: It rapidly reacts with pollutants in water, significantly reducing COD levels within a short time and quickly improving water quality.
Easy to use: Typically available in liquid or solid form, it is simple to dose and handle, requiring no complex equipment or processes.
High removal efficiency: It effectively removes various types of organic compounds, exhibits strong adaptability to different water qualities, and significantly reduces COD levels in water.
Environmentally friendly and non-polluting: High-quality COD removal agents do not cause secondary pollution, are eco-friendly, and do not interfere with subsequent water treatment processes.
Service Industries
Industrial wastewater treatment: This includes sectors such as chemical manufacturing, pharmaceuticals, textile dyeing, papermaking, and food processing. These industries generate large volumes of wastewater containing high concentrations of organic pollutants during production, often resulting in severely elevated COD levels. The use of COD removal agents can effectively reduce the COD concentration in such wastewater, enabling it to meet discharge standards or water quality requirements for reuse.
Municipal wastewater treatment: Urban domestic sewage contains various organic substances—such as human waste, detergents, and food residues—that elevate the COD levels of the wastewater. COD removal agents can be used in municipal wastewater treatment plants to help reduce COD concentrations and enhance overall treatment efficiency.
Recirculating water systems: In industrial recirculating cooling water systems, high levels of organic matter can promote microbial growth, adversely affecting system performance. By dosing COD removal agents, the COD concentration in the recirculating water can be controlled, thereby reducing microbial proliferation and ensuring stable operation of the system.
