Qingdao Conqinphi Environmental Technology Group Co., Ltd. is proud to present our High Salinity COD Wastewater Treatment System, specifically engineered for the demanding requirements of textile dyeing and finishing industries. With a compact design and a proven capacity of 10 cubic meters per day, this system delivers discharge-ready water, effectively reducing high salinity and organic load to meet strict environmental regulations. Built on years of field experience and backed by a facility spanning up to 30,000 square meters, our solution combines advanced oxidation, biological treatment, and membrane separation technologies to ensure reliable, cost-effective performance.
This system operates on standard 220V power and is designed for seamless integration into existing production lines. Whether you're dealing with reactive dye wastewater, high chloride content, or complex organic compounds, our tailored approach guarantees stable effluent quality. As a manufacturer with an annual export value exceeding US$10 million, we serve clients across North America, Europe, Asia, and more, providing turnkey solutions that reduce operational risks and accelerate compliance.
Key Features & Technical Specifications
- High Salinity Tolerance: Engineered to treat wastewater with salt concentrations up to 50,000 mg/L, using halophilic bacteria and specialized membrane processes.
- Advanced COD Removal: Multi-stage treatment (pre-treatment, biological, advanced oxidation, polishing) achieves COD removal rates above 95%.
- Discharge Ready: The final effluent meets common discharge standards (e.g., GB 4287-2012, local equivalents) and can be directly released or reused.
- Energy Efficient: Low power consumption due to optimized aeration and pump selection; power supply 220V, 50/60Hz.
- Fully Automated: PLC-based control with touchscreen interface, remote monitoring capability, and alarm systems for minimal operator intervention.
- Compact Footprint: Skid-mounted design saves floor space; customizable layout for different site constraints.
- Corrosion Resistant: All wetted parts made of duplex stainless steel, PVC, or fiberglass reinforced plastic (FRP) to withstand aggressive saline environments.

Frequently Asked Questions (FAQ)
-
Q: Can this system handle batch dyeing wastewater with varying salinity?
A: Yes, our system includes an equalization tank and a salinity-tolerant biological culture that can adapt to fluctuations up to 10% per hour. The PLC automatically adjusts aeration and chemical dosing. -
Q: What is the typical installation time?
A: For a standard skid-mounted unit, installation and commissioning usually take 2–4 weeks, depending on site preparation. We provide on-site supervision and training. -
Q: Does the system require any chemicals?
A: Minimal. We use coagulants (PAC/PAM) and occasional pH adjustment. Advanced oxidation (e.g., Fenton or ozone) can be added as an option for high COD loads. -
Q: What is the expected lifespan of the membranes?
A: With proper cleaning and maintenance, UF/RO membranes last 3–5 years. Biofilm carriers are replaced every 5–8 years. All consumables are readily available. -
Q: Can I reuse the treated water?
A: Yes, the discharge-ready water can be reused for rinsing or cooling. With additional polishing, it can even be reused for dyeing processes (depending on quality requirements). -
Q: What is the power consumption per cubic meter treated?
A: Typically 0.5–0.8 kWh/m³, depending on salinity and COD levels. The system is designed for energy efficiency. -
Q: Do you provide a warranty?
A: Yes, we offer a standard 2-year warranty on mechanical and electrical components. Extended warranties are available upon request. -
Q: How do I get a quote or test my wastewater?
A: Please send us a sample (2–5 liters) of your effluent with a complete analysis report. Our lab will run a treatability study and provide a customized proposal.
