A wastewater treatment project at a Jilin highway service area
Project Background
The service area generates an average of 200 m³ of wastewater daily, and the existing treatment system has been producing unstable effluent, putting the facility under pressure from environmental inspection authorities.
Solution
Utilizing Mingrui's anti-fouling PVDF hollow fiber membrane (pore size 0.1–0.3 μm), integrated with an intelligent aeration control system.
Modular design, optimized for low-temperature environments (guaranteed operation down to -20°C).
Technical Achievements
Effluent water quality: COD ≤ 30 mg/L, ammonia nitrogen ≤ 1.5 mg/L—meeting standards better than Class 1A under GB 18918-2002.
Energy Consumption Optimization: Membrane flux remains stable at 22 LMH, achieving an 18% energy savings compared to conventional processes.
Easy operations and maintenance: The chemical cleaning cycle has been extended to 6 months, reducing labor costs by 40%.
