Qingdao Conqinphi Environmental Technology Group Co., Ltd. presents the Automatic MBBR High-Salt High-COD Wastewater Treatment System — a robust, engineered solution designed for demanding industrial effluents. As a professional manufacturer established in 2015 with a factory spanning over 10,000 square meters and an annual export value exceeding US$10 million, we bring years of expertise in water treatment across global markets. This system combines Moving Bed Biofilm Reactor (MBBR) technology with automatic controls to effectively treat high-salinity and high-COD wastewater, ensuring stable discharge and operational simplicity.
Constructed from premium 304 stainless steel, this unit offers excellent corrosion resistance and durability even in harsh chemical environments. The system operates on a standard 220V power supply and handles a capacity of 10 cubic meters per hour. Its automatic control interface minimizes manual intervention, while the integrated MBBR media provides a large surface area for biomass growth, enabling efficient degradation of organic pollutants despite high salt concentrations.
Key Features & Benefits
- High-Salt & High-COD Tolerance — Specialized biofilm acclimation and media selection allow the system to handle salt levels up to 5% and COD loads exceeding 10,000 mg/L without performance drop.
- Automatic Operation — PLC-based controls adjust aeration, recirculation, and sludge wasting automatically, reducing labor costs and human error.
- 304 Stainless Steel Construction — Resists corrosion from chlorides and aggressive chemicals; extends equipment life significantly compared to carbon steel or plastic tanks.
- Compact Footprint — Skid-mounted design saves floor space; easy to install in existing facilities or new projects.
- Low Energy Consumption — Optimized aeration efficiency and minimal pumping requirements lower operating expenses.
- Scalable & Customizable — Modular configuration allows capacity expansion or integration with pre-treatment/post-treatment units as needed.

Detailed Process Description
The system incorporates a Moving Bed Biofilm Reactor (MBBR) that combines the advantages of activated sludge and biofilm processes. Wastewater enters an equalization tank with pH adjustment (optional), then flows into the MBBR tank filled with suspended plastic carriers. Air diffusers provide oxygen and keep the carriers in constant motion, ensuring high mass transfer rates. The biofilm attached to the carriers degrades organic matter and transforms toxic compounds. A settler or DAF unit follows to separate biomass, with sludge recirculation or disposal as needed.
For high-salt conditions, the system uses halotolerant microorganisms cultivated during startup. The PLC monitors DO, pH, ORP, and temperature, adjusting aeration and recirculation automatically to maintain optimal biological activity. The 304 stainless steel construction withstands chloride-induced pitting corrosion, making it ideal for industries like chemical processing, oil & gas, textile dyeing, and landfill leachate treatment.

Frequently Asked Questions (FAQ)
1. What is the maximum salt concentration this system can handle?
The standard system is designed for salinity up to 5% (as NaCl). For higher levels, we can pre-acclimate biomass or add a dilution step. Contact our engineers for a feasibility assessment.
2. Can the system be customized for different flow rates?
Yes, the MBBR is modular. We offer capacities from 1 m³/h to 200 m³/h. The 10 m³/h unit can be scaled up by adding parallel modules or larger tanks.
3. What kind of maintenance is required?
Routine maintenance includes checking aeration diffusers, cleaning sensors, and periodic sludge removal. The automatic PLC reduces manual monitoring. We provide a detailed maintenance manual with every system.
4. Is on-site installation support available?
Absolutely. Our installation team can travel to your site for setup and commissioning. Remote technical support is also available via video calls for training.
5. What is the power consumption of this unit?
Typical power consumption is approximately 8–12 kW, depending on the blower efficiency and organic load. The system includes energy-saving features such as variable frequency drives (VFD) for aeration.
6. Can the system treat wastewater with high oil & grease content?
Yes, but we recommend pre-treatment using a DAF or oil-water separator to avoid clogging the media. Our MBBR can handle moderate oil loads, but high oil content may inhibit biofilm growth.
7. How long does the startup and acclimation take?
For high-salt wastewater, acclimation of microorganisms typically takes 2–4 weeks. We can supply pre-acclimated inoculum to shorten the period. Full design conditions are reached within 30–45 days.
8. What certifications does the product have?
Our manufacturing processes are certified under ISO9001, ISO14000, OHSAS18001, SA8000, and others. Specific product certifications can be provided upon request based on your target market requirements.
