Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. As a professional manufacturer since 2015, we specialize in advanced wastewater treatment solutions. Our Customized High Ammonia Nitrogen Wastewater Treatment Equipment with Multi-Stage A/O and MBR Process is designed to efficiently remove high concentrations of ammonia nitrogen and organic pollutants, ensuring effluent meets stringent discharge standards. This integrated system combines the advantages of multi-stage anoxic/oxic (A/O) biological treatment with membrane bioreactor (MBR) technology, offering a compact footprint, stable operation, and excellent solid-liquid separation.
Our equipment is widely used in industries such as petrochemical, pharmaceutical, landfill leachate, livestock breeding, and municipal wastewater treatment. With a factory area of 10,000-30,000 square meters and over 200 employees, we have the capacity to deliver customized solutions tailored to your specific wastewater characteristics and flow rates. We export to markets worldwide, including North America, Europe, Southeast Asia, and Africa.
Key Features and Technical Specifications:
- Multi-stage A/O process: Enhanced nitrification and denitrification for high ammonia nitrogen removal efficiency (up to 95%+).
- MBR module: High-quality hollow fiber or flat sheet membranes with long service life (3-5 years) and low fouling rate.
- Customizable design: Available in containerized, skid-mounted, or concrete tank configurations to suit your space and installation requirements.
- Fully automatic PLC control: Real-time monitoring of DO, pH, ORP, and flow; remote control and alarm functions.
- Low energy consumption: Optimized aeration and recirculation design reduces operating costs.
- Compact footprint: MBR replaces secondary sedimentation tank, saving up to 50% space compared to conventional processes.
- High quality effluent: SS < 5 mg/L, NH₃-N < 5 mg/L (adjustable per standards).
