Qingdao Yimei Environmental Engineering Co., LTD., a pioneer in China's environmental protection technology, announced today that a set of intelligent sewage treatment equipment integrating the three core processes of AO+MBR+MBBR was dispatched from Qingdao to Bolivia on June 11, 2025. This order is another strategic move by the company in the South American market following the Paraguay project, highlighting the competitiveness of modular equipment in the international high-end environmental protection market.

Revolutionary process combination

For the special high-altitude working conditions of Bolivian customers, this system has achieved three major technological breakthroughs:

AO-MBR-MBBR co-treatment: The nitrogen and phosphorus removal efficiency reaches over 95%, and the effluent meets the Class I standard of the European Union

Special adaptation for altitude 3,800 meters: The pressurized aeration system addresses the pain point of insufficient dissolved oxygen at high altitudes

Smart Cloud Control Platform: Supports real-time monitoring of sludge concentration and membrane flux on mobile devices

Highlights of the project's breakthrough

This equipment will be deployed in the **[project location]** area of Bolivia. The main challenges and solutions include:

Low-temperature environment: Add a heat recovery module to ensure the stable operation of the MBR membrane group at -5℃
