The Tail water centralized treatment station project of Changsha Kaiyuan Industrial Park

**Rongjian Partners with Changsha Kaiyuan Industrial Park Centralized Wastewater Treatment Station**  

The Centralized Wastewater Treatment Station at Changsha Kaiyuan Industrial Park was experiencing operational challenges including inadequate treatment efficiency, high energy consumption, and inconsistent effluent quality, all of which compromised operational stability and cost-effectiveness.  

Rongjian Environmental Protection Chemical Packing Co., Ltd. delivered a customized high-efficiency chemical packing solution tailored to the station's specific needs. The packing media features an optimized surface area and porous structure, enhancing mass transfer and biodegradation efficiency of pollutants in the wastewater. Its superior hydraulic distribution characteristics also significantly reduced system operational resistance.  

By implementing Rongjian's specialized packing, the treatment station achieved notable improvements in processing capacity, consistently met effluent quality standards, and reduced energy consumption by approximately 15%. Operational and maintenance costs were also effectively controlled. This collaboration demonstrated Rongjian's technical expertise and project execution capabilities in the field of chemical packing, providing the customer with a reliable and highly efficient system solution.
