As a leading manufacturer based in Qingdao, China, Qingdao Conqinphi Environmental Technology Group Co., Ltd. has been dedicated to delivering high-performance wastewater treatment solutions since 2015. Our Multi-Stage High COD Wastewater Treatment Equipment is engineered to tackle the most challenging industrial effluents, combining robust 304 stainless steel construction with a multistage treatment process that ensures efficient removal of organic pollutants. With a designed capacity of 100 m³/day and a power consumption of only 5.5 kW, this system offers an optimal balance between treatment capacity and energy efficiency, making it an ideal choice for medium-scale industries facing high COD loads.
This equipment is built to meet the rigorous demands of industries such as food processing, pharmaceutical manufacturing, chemical production, and textile dyeing, where high-strength wastewater requires reliable and scalable treatment. The multi-stage design integrates primary sedimentation, anaerobic digestion, aerobic biological treatment, and advanced filtration, ensuring the effluent meets or exceeds local discharge standards. Whether you are looking to reduce environmental impact, comply with regulations, or recover resources, this system provides a comprehensive and customizable solution.
Key Features & Technical Specifications
- Multi-Stage Treatment Process: Combines physical, chemical, and biological stages to effectively reduce COD, BOD, TSS, and other contaminants. The sequential design ensures high removal efficiency, even with fluctuating influent quality.
- 304 Stainless Steel Construction: All wetted parts and main tanks are made of 304 stainless steel, offering excellent corrosion resistance, durability, and ease of cleaning. This material is suitable for a wide range of wastewater chemistries.
- High Capacity & Low Power: Designed for 100 m³/day throughput with a total installed power of only 5.5 kW, thanks to energy-efficient pumps, aerators, and control systems. This reduces operational costs significantly.
- Compact & Modular Design: The equipment footprint is minimized through optimized tank layout and piping, making it suitable for sites with limited space. Modular components allow for future capacity expansion.
- PLC-Based Automation: Optional PLC control with HMI touch screen enables automatic operation, real-time monitoring, and remote access. Parameters such as dissolved oxygen, pH, and flow rate can be adjusted easily.
- Low Sludge Production: Advanced biological treatment stages minimize sludge generation, reducing disposal costs and handling requirements.
- Compliance Ready: The system is designed to meet international discharge standards, including those for COD, BOD, and nutrient removal. Customizable to meet specific local regulations.

How the Multi-Stage Process Works
The treatment train is designed to handle high-strength wastewater through a series of carefully engineered steps:
- Primary Sedimentation: Large solids and settleable particles are removed, reducing the load on downstream biological stages.
- Anaerobic Digestion: Organic matter is broken down by anaerobic microorganisms, producing biogas and reducing COD by 50–70%.
- Aerobic Biological Treatment: Activated sludge or biofilm process further degrades remaining organics, achieving high removal efficiency.
- Secondary Clarification: Biomass is separated from treated water, with sludge recirculated or wasted.
- Tertiary Filtration (optional): Sand or membrane filtration polishes the effluent to meet stringent discharge limits.
This multi-barrier approach ensures reliable performance even when influent characteristics vary. The system is designed for minimal operator intervention, with automated controls and alarms.
Benefits for Your Business

Frequently Asked Questions (FAQ)
Q1: What types of wastewater can this equipment treat?
A: This multi-stage system is designed for high-COD industrial wastewater, including effluents from food processing, beverage, dairy, pharmaceutical, chemical, textile, and pulp & paper industries. It can handle COD levels up to 20,000 mg/L and is adaptable to other contaminants.
Q2: Can the equipment be customized for different capacities?
A: Yes, the modular design allows for capacity adjustments from 50 m³/day to 500 m³/day or more. We can also modify the number of stages and add tertiary treatment based on your effluent requirements.
Q3: What is the typical COD removal efficiency?
A: Under normal operating conditions, the system achieves 95–99% COD removal, bringing effluent COD below 100 mg/L. Higher removal rates are possible with additional polishing steps.
Q4: How much space is required for installation?
A: The footprint depends on the specific configuration. A typical 100 m³/day unit occupies approximately 8m x 6m x 4m (L x W x H). We provide detailed layout drawings during the design phase.
Q5: Is the equipment easy to operate? Do we need specialized staff?
A: The system is equipped with an optional PLC-based automation system that simplifies operation. Basic training is provided, and the intuitive HMI interface allows operators to monitor and adjust parameters without deep technical expertise.
Q6: What is the warranty period and after-sales service?
A: We offer a standard 12-month warranty from the date of commissioning. Extended warranties are available. Our service team provides remote support, spare parts, and on-site assistance as needed.
Q7: Can the treated water be reused?
A: Yes, with optional tertiary filtration (e.g., UF/RO), the treated effluent can meet quality standards for non-potable reuse, such as irrigation, cooling tower makeup, or cleaning. We can design a water reuse system based on your specific needs.
Q8: What certifications does your company hold?
A: Our manufacturing facility is certified under ISO9001, ISO14000, OHSAS18001, and several other quality management systems. We ensure that every product is built to international standards. Certificates are available upon request.
