Product Description
VPSA Oxygen Generator (VPSA Oxygen System) is the core oxygen
supply equipment for the aeration process in the sewage treatment
industry. Based on Vacuum Pressure Swing Adsorption (VPSA)
technology, it can efficiently separate oxygen from air, providing
sufficient oxygen for microorganisms in sewage and promoting
pollutant degradation. It features core advantages such as energy
saving, large flow rate, and stable operation. With an ultra-low
energy consumption of 0.32kWh/Nm³ as its biggest highlight, it
saves more than 40% energy compared with traditional blast
aeration, and its flow rate of 300Nm³/h fully meets the needs of
aeration tanks in medium and large sewage treatment plants.
As a mainstream equipment for pressure swing adsorption for oxygen
production, the VPSA Oxygen Generator requires no chemical
reagents, making it green and environmentally friendly. The oxygen
it produces with a purity of 92-94% can significantly improve
aeration efficiency, shorten sewage treatment cycles, and reduce
operating costs.

Why Choose Energy-Saving VPSA Oxygen Generator for Sewage Treatment
Aeration?
The core link of sewage treatment is aeration. By introducing
oxygen into sewage, aerobic microorganisms are cultivated to
degrade pollutants such as organic matter and ammonia nitrogen.
Traditional aeration methods use air compressors (blast aeration),
where the oxygen content in air is only 21%, resulting in low
aeration efficiency and high energy consumption, accounting for
50-70% of the total energy consumption of sewage treatment plants.
In contrast, the oxygen with 92-94% purity produced by the VPSA
Oxygen Generator can increase aeration efficiency by more than 4
times, significantly reducing aeration time and energy consumption.
The flow rate of 300Nm³/h accurately matches the needs of sewage
treatment plants with a daily treatment capacity of 50,000-100,000
tons, and the ultra-low energy consumption of 0.32kWh/Nm³ is its
core competitiveness. Calculated based on 24 hours of daily
operation and 300 days of annual operation, the annual power
consumption of the equipment is only 300×0.32×24×300=691,200kWh.
Compared with traditional blast aeration (0.6kWh/Nm³), it saves
approximately 300,000 yuan in annual electricity costs (calculated
at 1 yuan/kWh), significantly reducing pressure swing adsorption
oxygen plant cost.
In addition, the oxygen purity of the VPSA Oxygen Generator is
stable, which can avoid the decline in microbial activity caused by
insufficient oxygen, ensure the compliance rate of sewage
treatment, and reduce the risk of fines due to substandard water
quality. Its modular design supports on-demand capacity expansion.
If the sewage treatment plant undergoes subsequent upgrade and
renovation, modules can be directly added without replacing the
main equipment, reducing expansion costs.
Procurement Key Points: Core Selection Criteria for Sewage
Treatment Plants
When purchasing a VPSA Oxygen Generator, sewage treatment plants
should focus on three core aspects: "energy efficiency, stability,
and adaptability". In terms of energy efficiency, priority should
be given to equipment with a unit energy consumption ≤0.35kWh/Nm³,
and suppliers should be required to provide third-party energy
consumption test reports; in terms of stability, it is necessary to
confirm that the equipment has a continuous operation time ≥7,000
hours/year and a failure shutdown rate ≤1%, and priority should be
given to psa oxygen plant manufacturer with cases in the sewage
treatment industry; in terms of adaptability, the required flow
rate should be calculated according to the volume of the aeration
tank and dissolved oxygen demand to ensure that the equipment
parameters match the process requirements.
In addition, after-sales support is crucial. The shutdown of sewage
treatment plant equipment will result in the inability to treat
sewage. Therefore, it is necessary to select suppliers that can
provide 24-hour on-site service and timely supply of spare parts,
requiring a warranty period ≥1 year and a warranty period of ≥3
years for core components (molecular sieves, fans). At the same
time, suppliers can be required to provide value-added services
such as installation, commissioning, and operator training to
ensure the rapid commissioning and standardized operation of the
equipment.
With its advantages of ultra-low energy consumption and high
aeration efficiency, the VPSA Oxygen Generator has become the core
equipment for energy-saving transformation in the sewage treatment
industry. The configuration of 300Nm³/h flow rate and 0.32kWh/Nm³
energy consumption accurately matches the needs of medium and large
sewage treatment plants. Its Vacuum Pressure Swing Adsorption
Oxygen Systems technology can provide economical, stable, and
environmentally friendly oxygen supply support for sewage treatment
aeration, helping sewage treatment plants achieve energy
conservation, consumption reduction, quality improvement, and
efficiency enhancement.
