The dyeing and printing industries are essential for global commerce but are notorious for generating wastewater that is highly colored and laden with various chemical pollutants, including those contributing to Chemical Oxygen Demand (COD). Achieving sustainable water management in these sectors requires advanced treatment solutions. NINGBO INNO PHARMCHEM CO.,LTD. offers Dicyandiamide Formaldehyde (DCDA) Polymer, a key chemical agent that significantly contributes to making these industries more environmentally responsible.

Wastewater from dyeing and printing operations often contains a complex mix of dyes, fixing agents, and auxiliaries. These substances result in high levels of color and COD, posing significant challenges for conventional wastewater treatment plants. The ability to effectively remove color and reduce COD is paramount for complying with environmental regulations and for enabling water reuse, which is increasingly important in water-scarce regions.

DCDA Polymer (CAS No. 55295-98-2) has emerged as a highly effective solution for these specific challenges. As a cationic polymer, it exhibits exceptional performance in decolorizing wastewater by neutralizing the negatively charged dye molecules. This process leads to rapid flocculation, allowing the colored particles to be efficiently removed through sedimentation or air flotation. The efficiency of this textile effluent color removal process is a critical benefit for the dyeing and printing sectors.

Beyond color removal, DCDA Polymer also plays a vital role in reducing the COD of the wastewater. By binding to and facilitating the removal of organic compounds that cause high COD, the polymer contributes to cleaner effluents. Studies show that DCDA polymers can reduce COD levels by 50% to 80%, which is a significant improvement for many industrial discharge streams. This capability makes it an indispensable wastewater COD reduction chemical.

The sustainable aspect of DCDA Polymer lies not only in its performance but also in its formulation. It is free from heavy metal ions like aluminum and chlorine, meaning it does not introduce secondary pollutants into the water. This makes it a much cleaner and environmentally friendly option compared to some traditional treatment chemicals. By choosing DCDA Polymer, companies are opting for a solution that aligns with the principles of green chemistry and sustainable industrial practices.

The application of DCDA Polymer is versatile within the dyeing and printing industries. It is effective against a wide range of dyes, including reactive, acid, and disperse dyes. Its usage is typically straightforward: dilute the polymer with water and dose it into the wastewater. For optimal results, adjusting the pH of the wastewater to a neutral range (pH 7-9) is recommended. Furthermore, combining DCDA Polymer with inorganic coagulants like Polyaluminum Chloride (PAC) can enhance performance and reduce overall treatment costs, especially when dealing with very high color and COD loads.
