Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. – your trusted partner in industrial wastewater treatment. As a manufacturer established in 2015 with a 10,000–30,000 m² factory and annual export value exceeding US$10 million, we are proud to introduce our High-Strength COD 40,000 mg/L Industrial Wastewater Treatment System integrating DAF (Dissolved Air Flotation) and MBBR (Moving Bed Biofilm Reactor) technologies. This robust system is engineered to handle extremely high organic loads, delivering reliable performance for industries facing challenging wastewater streams. With 380V/50Hz power compatibility and customizable configurations, it offers a cost-effective and efficient solution.
Our system combines physical-chemical and biological treatment stages to achieve outstanding removal rates. The DAF unit efficiently removes suspended solids, oils, and greases, while the MBBR reactor provides high-rate biological degradation of organic pollutants. Designed for continuous operation, it minimizes downtime and maintenance. Below you will find the key technical specifications and advantages of this system.
Key Features & Technical Specifications
- High COD Removal Efficiency: Capable of treating influent COD up to 40,000 mg/L, with effluent quality meeting discharge standards (customizable).
- Integrated DAF + MBBR Process: Dual-stage treatment ensures effective removal of solids, oils, and biodegradable organics.
- Standard 380V/50Hz Power Supply: Compatible with industrial grids in many regions; voltage/frequency can be customized upon request.

Advantages for Your Business
- Reliable performance under extreme loads: The system is specifically designed to handle high-strength wastewater, ensuring stable operation even with fluctuating influent quality.
- Reduced chemical usage: The DAF unit uses dissolved air for flotation, minimizing chemical coagulants and flocculants compared to conventional systems.
- Low sludge production: MBBR biomass is attached to moving media, resulting in less excess sludge and lower disposal costs.
- Easy scalability: Modular design allows for future expansion or integration with existing treatment trains.
- Quick installation: Pre-assembled and tested before shipment, reducing on-site work and commissioning time.
- Global support: Our team of 201-300 employees provides technical documentation, remote troubleshooting, and on-site service if needed.

Frequently Asked Questions
-
Q: Can this system treat wastewater with COD above 40,000 mg/L?
A: The system is designed for up to 40,000 mg/L. For higher loads, we can incorporate additional stages (e.g., anaerobic pretreatment) or adjust the MBBR design. Please provide your specific parameters. -
Q: What is the typical effluent COD after treatment?
A: Effluent quality depends on the influent characteristics and regulatory requirements. Generally, with proper design, COD can be reduced to below 500 mg/L or even lower. We optimize the system to meet your target. -
Q: Does the system require a continuous chemical supply?
A: The DAF stage may require coagulants/flocculants for optimal performance, but chemical consumption is minimal. The MBBR stage is biological and does not require chemicals. -
Q: What is the power consumption of the system?
A: Power consumption varies with size and configuration. For a typical 100 m³/day system, it is approximately 15-25 kW. We can provide a detailed estimate based on your flow rate. -
Q: Can the system be operated in cold climates?
A: Yes, insulation and heating options are available. The MBBR process can operate down to 10°C, but lower temperatures may affect biological activity. We can recommend additional measures. -
Q: What is the warranty period?
A: Standard warranty is 12 months from commissioning or 18 months from shipment, whichever comes first. Extended warranty options are available upon request. -
Q: How long does it take to deliver and install?
A: Lead time depends on the system size and customization. Typically it is 30-60 days from order confirmation. Installation and commissioning can be completed within 2-4 weeks on-site. -
Q: Do you provide after-sales service and spare parts?
A: Yes, we offer technical support, remote diagnostics, and a comprehensive spare parts catalog. Our global network ensures timely assistance.
