High Light	VPSA oxygen generator for sewage treatment ，energy-saving VPSA oxygen system ，300Nm³/h VPSA oxygen generator

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.

VPSA Oxygen Generator for Sewage Treatment Aeration

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.

In addition to PSA Oxygen Generators, we also produce VPSA Oxygen Generators, storage tanks, heat exchangers and other products. If you are interested in VPSA Oxygen Systems or other products, please feel free to send an email to info@gneeheatex.com. We will be very happy to serve you.
