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. Our PSA Oxygen Generator (Pressure Swing Adsorption Oxygen Generator) is a specialized industrial oxygen system that operates on PSA technology to physically separate oxygen from ambient air using high-efficiency molecular sieves, delivering 95% pure oxygen with no chemical additives.
As a high-performance pressure swing adsorption oxygen plant, it addresses the limitations of traditional aeration methods—such as low oxygen transfer efficiency and high energy consumption—with stable output, adjustable purity, and compact design. This 35Nm³/h 95% purity model, customized for wastewater treatment applications, boosts microbial activity by 40%, shortens treatment cycles by 25%, and serves as the preferred aeration equipment for medium-scale wastewater plants (5,000-10,000 m³/day).

PSA Oxygen Generator Advantages Over Traditional Aeration Methods
Wastewater aeration requires high oxygen transfer, low energy consumption, and stable operation—all achieved by our PSA oxygen generator:
- Efficiency Boost 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 Savings 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 optimal microbial growth.
PSA System vs. VPSA Oxygen Generator: Wastewater Treatment Applications
Both technologies belong to pressure swing adsorption oxygen plant systems, but their wastewater applicability differs:
- PSA System for Oxygen: Advantages include 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 Oxygen Generator: Uses vacuum regeneration for lower energy consumption but has larger size, higher initial investment, and longer start-up time. It suits large plants (≥20,000 m³/day) with stable aeration needs.
- Key Tradeoff: 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 limitations of traditional aeration methods, while its cost advantage delivers significant long-term savings for medium-scale wastewater plants.
For wastewater plants aiming to improve treatment efficiency, reduce operating costs, and comply with environmental regulations, this PSA system represents a reliable, future-oriented investment. As wastewater treatment standards tighten globally, PSA oxygen generators will play an increasingly critical role in promoting the green, efficient development of the wastewater treatment industry.
