Industrial wastewater, particularly from sectors like textile dyeing and printing, often presents a significant environmental challenge due to its high color intensity and complex chemical composition. NINGBO INNO PHARMCHEM CO.,LTD. explores the fundamental chemistry that makes Dicyandiamide (DCDA) a cornerstone in the development of powerful wastewater decolorizing agents.

At its core, effective wastewater decolorization relies on transforming dissolved dye molecules into insoluble forms that can be physically removed. This is typically achieved through a process involving coagulation and flocculation. Dicyandiamide, when reacted with formaldehyde and other agents, forms polymers such as Dicyandiamide formaldehyde resin. These polymers are often cationic polyelectrolytes, meaning they carry a positive charge.

Dye molecules present in wastewater are generally anionic or carry a negative charge due to their chromophores and functional groups. The positively charged Dicyandiamide-based flocculants are designed to neutralize these negative charges. When introduced into the wastewater, the cationic polymer chains attach themselves to the anionic dye molecules. This neutralization process destabilizes the dye molecules, disrupting their solubility and aggregation state.

Following charge neutralization, the process of flocculation begins. The destabilized dye molecules, along with other suspended solids, begin to aggregate. The polymer chains themselves can also bridge between different dye molecules and particles, creating larger, more robust flocs. These flocs, being heavier and larger than the original dye molecules, can then be readily separated from the water through sedimentation or filtration processes.

The efficacy of Dicyandiamide formaldehyde resin in this role is well-documented. It boasts a strong affinity for a wide range of dyes, including reactive dyes, acid dyes, and disperse dyes, which are commonly used in the textile industry. The efficiency of these flocculants is often measured by their ability to achieve high color removal percentages and significant reductions in COD levels, indicative of overall organic pollution reduction.
