Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. As a leading manufacturer established in 2015 with a factory spanning 10,000–30,000 square meters and over 200 skilled employees, we specialize in delivering high-performance wastewater treatment solutions. Our 304 Stainless Steel COD 40,000 mg/L High-Strength Wastewater Treatment System with PLC Control is engineered to tackle the most demanding industrial effluents, ensuring reliable operation and compliance with stringent discharge standards. With an annual export value exceeding US$10 million, our systems are trusted by clients across North America, Europe, Southeast Asia, the Middle East, and beyond.
This robust system is designed for high-strength wastewater containing up to 40,000 mg/L COD, making it ideal for industries such as chemical processing, pharmaceuticals, food and beverage, textile dyeing, and landfill leachate treatment. The integration of PLC (Programmable Logic Controller) automation provides precise process control, real-time monitoring, and remote operation capabilities, reducing manual intervention and enhancing operational efficiency.
Key Features & Advantages
- Superior Material & Durability: Constructed from 304 stainless steel, the system resists corrosion and withstands harsh chemical environments, ensuring long service life and low maintenance.
- High-Efficiency Treatment: Multi-stage treatment process combining physical screening, chemical coagulation, biological degradation, and advanced oxidation to achieve high COD removal rates.
- PLC Automation: User-friendly touchscreen interface with customizable parameters; supports data logging, alarm functions, and remote monitoring via Ethernet or 4G.
- Energy-Saving Design: Variable frequency drives (VFD) on pumps and blowers optimize energy consumption, reducing operational costs by up to 20% compared to conventional systems.
- Compact Footprint: Modular design allows easy installation in limited spaces; skid-mounted or containerized options are available for quick deployment.
- Flexible Configuration: Customizable flow rates (from 1 m³/h to 100 m³/h), additional treatment stages (e.g., MBR, UF, RO), and effluent quality targets to meet local regulations.
