The global textile industry is a cornerstone of modern commerce, but it also faces significant environmental scrutiny, particularly concerning water pollution. The dyeing and finishing processes generate vast quantities of wastewater laden with complex, synthetic dyes and other chemicals. This effluent, characterized by its intense color and high Chemical Oxygen Demand (COD), poses a severe threat to aquatic ecosystems and human health if discharged untreated. Addressing this challenge requires innovative and efficient treatment solutions. NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of this effort, offering a high-performance Water Decoloring Flocculant designed to effectively treat high-chromaticity industrial wastewater.

The problem with textile effluent is multifaceted. The dyes used are often stable, complex aromatic compounds designed to resist fading, which makes them inherently difficult to break down through natural biological processes. When this colored water enters rivers and lakes, it blocks sunlight, inhibiting photosynthesis in aquatic plants and disrupting the entire food web. Furthermore, many dyes and auxiliary chemicals are toxic or carcinogenic, creating long-term environmental hazards. Traditional wastewater treatment methods often struggle to remove color effectively, necessitating specialized chemical intervention. This is where flocculation technology becomes critical.

Introducing a Superior Solution: The Quaternary Cationic Polymer Flocculant

Our flagship product, a specialized Water Decoloring Flocculant, is a quaternary cationic polymer that offers a powerful solution for this industrial challenge. As a viscous, colorless to light-colored liquid, it is engineered specifically for decoloring, flocculation, and the reduction of COD. The core of its effectiveness lies in its chemical structure. As a cationic polymer, it carries a strong positive charge in aqueous solutions. Most textile dyes, such as reactive, acid, and direct dyes, are anionic, meaning they carry a negative charge. When our flocculant is introduced into the wastewater, a powerful electrostatic attraction occurs. The positive charges on the polymer chain neutralize the negative charges of the dye molecules.

This charge neutralization is the first step. It destabilizes the fine, colloidal dye particles that are suspended in the water. The long polymer chains then act as bridges, gathering these destabilized particles together into larger, heavier clumps called flocs. This process, known as flocculation, makes the pollutants much easier to remove from the water through simple physical processes like sedimentation or air flotation. The result is a dramatic clearing of the water and a significant reduction in pollutant load.

Technical Specifications and Performance

Our Water Decoloring Flocculant is distinguished by its high efficacy and quality. Key technical specifications include:
- Solid Content: 49.0% - 51.0%
- pH (1% water solution): 3.0 - 5.0
- Ionicity: Cationic
- Solubility: Fully water-soluble

The performance of this product is exceptional, consistently achieving a decoloring rate higher than 95% in typical printing and dyeing wastewater. In addition to its primary decoloring function, it also plays a crucial role in reducing the overall pollution level, with a COD elimination rate between 40% and 75%. This dual-action capability makes it an invaluable tool for industries aiming to meet stringent environmental discharge standards.

Application Fields and Methods

This flocculant is primarily suited for the decoloring of printing and dyeing wastewater but is also highly effective in treating high-colority effluent from dyestuff intermediate production facilities. The application process is straightforward and can be easily integrated into existing treatment systems.

1. The product should first be diluted with 10 to 50 times its volume in water to create a working solution.
2. This solution is then added directly to the wastewater stream.
3. The pH of the wastewater should be adjusted to a range of 4-11 for the product to be effective, with the optimal performance observed in a pH range of 7-8.
4. After addition, the mixture should be stirred for several minutes to ensure complete mixing and floc formation.
5. Following agitation, the flocs can be removed by allowing them to settle (precipitation) or by using an air flotation system, leaving behind clear, treated water.

For wastewater with particularly high color intensity and COD levels, the flocculant can be used in conjunction with inorganic coagulants (like polyaluminum chloride). This combination can often enhance performance and reduce overall treatment costs. The precise dosage and order of agent addition should be determined through flocculation tests based on the specific characteristics of the wastewater.
