Problems faced
Printing and dyeing wastewater contains a large amount of dye residues and high concentration of COD, and the flocculation and sedimentation efficiency is low, which makes it difficult for the effluent to meet the standards and the treatment load is high.
Requirement: Find a suitable polymer flocculant to optimize the water purification process.
Recommended products
Anionic polyacrylamide (APAM)
Can be applied to:
▼ Mining wastewater treatment (tailings water)
▼ Printing and dyeing/textile wastewater treatment
▼ Steel and metallurgical industry
Solutions and advantages
In view of the high chroma and high suspended solids characteristics of printing and dyeing wastewater, we recommend medium and high molecular weight APAM, combined with the front-end coagulant for secondary coagulation and sedimentation. After implementation, the customer's chroma was reduced by more than 80%, the effluent suspended solids compliance rate was greatly improved, and the system operation was more stable.
