HANQI Environmental has recently been awarded the EPC contract for a concentrated wastewater treatment system in a major green chemical industrial park in Jiangsu, China. Located in a land reclamation area with complex geological conditions, the project faces multiple challenges, including a tight schedule, high standards, and limited space.

To address these challenges, HANQI provides end-to-end services—from design and procurement to construction—and adopts an innovative all-steel structure with a highly integrated modular layout. This approach maximizes the use of limited space, significantly saves land, shortens the construction period, and controls costs.

Technologically, the system integrates core processes such as biological treatment, oxidation, and sedimentation. It effectively removes pollutants like total nitrogen and COD, ensuring the treated effluent meets stringent discharge standards.

The successful implementation of this project not only provides key technical support for the industrial park’s near-zero emission goals but also sets a replicable example of high-standard wastewater treatment for coastal areas with limited land resources.
