Beijing's second-largest reclaimed water plant-Xiaohongmen adopts the UF and RO membrane technology independently innovated and developed by BOW,  with a daily processing capacity of  600,000 m³.

The project adopts MBR technology with the processing volume of 45000 m³/d. Convert the sewage to surface water Grade Ⅳ as the effluent. It is a milestone project with the capacity of over 10,000 tons effectively protect Beijing’s water environment.

The project utilizes UF membrane technology to treat the sewage with the processing volume of 1,000,000 m³/d. It is currently considered the largest in scale. The effluent meets the requirements for reclaimed water and is primarily used for replenishing rivers and lakes within Beijing, industrial reuse.
