Product Description
35Nm³/h 95% Purity PSA Oxygen System for Wastewater Treatment
Wastewater biological treatment, the core process in municipal and industrial wastewater plants, relies on aeration systems to supply oxygen for aerobic microorganisms that decompose organic pollutants, nitrify ammonia nitrogen, and purify water quality. The PSA oxygen generator operates on pressure swing adsorption technology to physically separate oxygen from ambient air using high-efficiency molecular sieves, delivering 95% pure oxygen with no chemical additives.

PSA Oxygen Generator vs Traditional Aeration Methods
Wastewater aeration requires high oxygen transfer, low energy consumption, and stable operation—all achieved by PSA oxygen generators:
- Efficiency vs Air Blowers: Traditional air blowers supply 21% oxygen, with 79% nitrogen increasing aeration volume and energy waste. 95% pure oxygen raises DO levels in bioreactors from 2-3mg/L to 6-8mg/L, accelerating microbial degradation and reducing aeration time by 25%.
- Cost vs Liquid Oxygen: Liquid oxygen for aeration costs approximately $120/day for a 5,000 m³/day plant. The PSA system's daily electricity cost is only about $25.92, saving approximately $34,608 annually.
- Stability vs Oxygen Cylinders: Oxygen cylinders require frequent replacement, leading to DO fluctuations. The PSA system operates 24/7 with a 0.8Nm³ buffer tank ensuring stable DO levels for microbial growth.
PSA vs VPSA Oxygen Generators for Wastewater Treatment
Both technologies belong to pressure swing adsorption oxygen plants, but their wastewater applicability differs:
- PSA System: Compact size, fast start-up (≤5 minutes), and low maintenance—ideal for medium-scale plants (5,000-10,000 m³/day) with fluctuating organic loads.
- VPSA System: Uses vacuum regeneration for lower energy consumption but has larger size, higher initial investment, and longer start-up time. Suitable for large plants (≥20,000 m³/day).
- Key Advantage: For 70% of wastewater plants, the PSA system's balance of cost, flexibility, and efficiency makes it more practical than VPSA.
Conclusion
The 35Nm³/h 95% purity PSA System for Oxygen revolutionizes wastewater aeration by combining advanced PSA technology with wastewater-specific design. Its high oxygen transfer efficiency, low energy consumption, and corrosion resistance solve the core challenges of traditional aeration methods, while delivering significant long-term savings for medium-scale wastewater plants.
For wastewater plants aiming to improve treatment efficiency, reduce operating costs, and comply with environmental policies, this PSA system is a reliable, future-oriented investment that plays a critical role in promoting green, efficient development of the wastewater treatment industry.
