Coats Line (Shenzhen) Co., Ltd. is a subsidiary of British Coats  Group in. Its main products include sewing thread, embroidery thread and zipper. Wastewater treatment in this project belongs to mixed sewage of printing and dyeing wastewater and a small amount of domestic wastewater. The water quality is characterized by high COD concentration, insufficient nitrogen and phosphorus nutrients, and poor biochemical property.

 

The maximum processing capacity of the system is 2800t/d. After transforming, the system  abandoned the original coagulation sedimentation section. After homogenization and pH adjusting, wastewater drained into the aeration tank. This transformation can save 300 thousand flocculation cost for customers, reduce the original disposal cost of physical and chemical sludge effectively, and avoid secondary pollution at the same time. The specific process flow is as follows:
