Wastewater treatment is evolving from “fixed process flows” toward early prediction, dynamic response, and flexible adjustment, which are becoming the core capabilities for coping with variable influent quality and enhancing overall system resilience.

Traditional civil-engineered wastewater treatment plants are structurally bulky, involve long construction periods, are difficult to expand or relocate, require large land areas, and struggle to meet future demands for flexible and efficient development

This process combines the Fully Adjustable Biological Treatment System (heterotrophic) and the Sulfur-Based Autotrophic Advanced Treatment System (autotrophic).

The heterotrophic biological treatment system achieves 10%–30% denitrification cost savings. The sulfur-based autotrophic advanced treatment system delivers a 62.5% reduction in denitrification cost. When integrated together, the combined system reaches 70%–80% total savings on denitrification chemical costs, along with 50% electricity savings. It is suitable for the treatment of medium- to low-strength wastewater with a low C/N ratio.

The system achieves simultaneous removal of organic matter and nitrogen through coupled reactions in anaerobic, anoxic, and aerobic multi-zones, allowing microbial communities to form highly efficient biofilms on carriers with high specific surface area.

For industrial wastewater with high COD, high ammonia nitrogen, oil content, and complex organic pollutants, a facultative multi-zone biological reaction system is employed.

It operates efficiently and generates a small amount of sludge, which can be applied in various industries such as food, chemical, and pharmaceutical sectors.
