Horizontal tube sedimentation separation technology

This technology is a pioneering invention that truly realizes the Ha Zhen "shallow pool" theory, micro divides the settling section, shortens the settling distance, greatly improves the solid-liquid separation efficiency, and forms the core advantages of high efficiency, energy saving, and small footprint.

50% land saving and doubling sedimentation efficiency

Catalytic Ceramic Membrane Technology

Based on a deep cooperation with Tsinghua University, ceramic membranes are loaded with catalysts that have both physical interception and catalytic reactor functions. Combined with in-situ ozone, they can effectively remove odor substances and organic pollutants, and have self-cleaning capabilities, without the need for acid-base cleaning in daily life.

Daily acid-base free cleaning to solve the problem of odor in drinking water

AOA technology

Academician Peng Yongzhen pioneered the "Anaerobic/Aerobic/Hypoxia" (AOA^®) treatment process both domestically and internationally, which has the advantages of fully utilizing carbon sources, energy conservation and consumption reduction, low infrastructure costs, simple operation and management, and strong resistance to shock loads. It has great potential for application in the upgrading and energy-saving of sewage treatment plants.

Anaerobic ammonia oxidation technology

The multi-stage A/O coupled partial anaerobic ammonia oxidation process is a mud film coupling method, which removes nitrogen and phosphorus through short-range denitrification partial anaerobic ammonia oxidation and short-range nitrification partial anaerobic ammonia oxidation. Usually composed of 2-4 stages of hypoxia/aerobic sequence arrangement. This process uses anaerobic ammonia oxidizing bacteria to achieve partial anaerobic ammonia oxidation, which can fully utilize the carbon source in the raw water and achieve deep and efficient nitrogen and phosphorus removal.
