PSA Oxygen Gas Generator is an industrial oxygen supply equipment designed for corrosive environments. Based on pressure swing adsorption technology, it adopts corrosion-resistant materials and special molecular sieves, featuring core advantages of acid and alkali corrosion resistance, stable oxygen supply, and reliable operation. As a specialized model of psa gas plant, the 40Nm³/h flow rate can accurately match the oxidation reaction needs of pharmaceutical wastewater treatment. It provides sufficient oxygen for processes such as Fenton oxidation and ozone oxidation, accelerating pollutant degradation, and serving as a key equipment for pharmaceutical enterprises to achieve compliant discharge of wastewater.

Targeting the corrosive environment of pharmaceutical wastewater treatment, the PSA Oxygen Gas Generator has undergone comprehensive optimizations from materials to structure:
- Core components (adsorption towers, pipelines, valves) are all made of 316L stainless steel, whose corrosion resistance is 3 times higher than that of 304 stainless steel, capable of resisting erosion by organic acids and sulfides.
- The molecular sieve selects corrosion-resistant lithium-based molecular sieve, forming a protective layer through surface coating technology to avoid damage to adsorption performance by corrosive gases volatilized from wastewater.
- The pretreatment system adds a corrosion-resistant filter, with filter elements made of PTFE material, which can filter 99% of acidic mist and dust to protect molecular sieves from contamination.
In terms of process adaptation, the equipment supports linkage with the wastewater treatment PLC system, automatically adjusting oxygen flow rate according to the online COD (Chemical Oxygen Demand) monitoring data of the oxidation tank:
- When the COD concentration is higher than 2000mg/L, the flow rate is automatically increased to 40Nm³/h to enhance oxidation.
- When the COD drops below 500mg/L, it is reduced to 20Nm³/h to save energy consumption.
This intelligent adjustment capability reduces the specific oxygen consumption by 15%, saving about 80,000 RMB in electricity fees annually. In addition, the equipment’s operating pressure (0.5-0.7MPa) can directly match the pressure requirements of the Fenton reactor, eliminating the need for additional booster equipment and simplifying the system layout.
The strong corrosiveness of the pharmaceutical wastewater treatment environment requires that the maintenance of the PSA Oxygen Gas Generator focuses more on corrosion protection.
- Daily maintenance: Inspect the equipment surface for corrosion traces. If rust spots appear, promptly treat them with stainless steel-specific cleaning agents and touch up with anti-corrosion paint; replace the PTFE filter element of the pretreatment system once a week to prevent corrosives from penetrating the filter element and contaminating the molecular sieve.
- Monthly maintenance: Test the air tightness of the adsorption tower using the helium leak detection method to ensure the leak rate is ≤0.1% per year, preventing oxygen leakage and infiltration of corrosive gases; lubricate the valves once a quarter with corrosion-resistant grease (such as perfluoropolyether grease) to avoid failure of ordinary grease due to corrosion.
- Molecular sieve maintenance: The molecular sieve is a key component. Sample and test its adsorption performance every six months. If the adsorption capacity decreases by more than 10%, conduct regeneration treatment (introduce superheated steam); its normal service life is 3-4 years, and corrosion-resistant molecular sieves must be replaced after expiration – ordinary molecular sieves are prohibited as substitutes.
It is recommended to sign an annual maintenance agreement with psa oxygen plant manufacturer, where professional personnel perform in-depth corrosion protection maintenance, including passivation treatment of pipeline inner walls and corrosion-resistant sealing of the electrical system. This can extend the equipment’s service life to more than 6 years, far higher than the industry average (3-4 years).
With its precise 40Nm³/h flow rate and excellent corrosion resistance, the PSA Oxygen Gas Generator has become the core oxidation oxygen supply equipment for pharmaceutical wastewater treatment. Its psa gas plant technology can not only meet the oxygen supply needs of advanced oxidation but also adapt to harsh corrosive environments, helping pharmaceutical enterprises achieve compliant discharge of wastewater and green production.
