B2B buyers in the sewage treatment industry face challenges such as:
Low Dissolved Oxygen (DO) in aeration tanks leading to poor microbial activity.
High energy costs from mechanical aeration systems.
Inconsistent oxygen supply from bulk delivery, causing operational disruptions.
Increasing environmental regulations on discharge water quality.
By installing an on-site PSA oxygen generator, facilities can:
Increase oxygen transfer efficiency by up to 40% compared to air aeration.
Reduce sludge volume and improve nitrification-denitrification cycles.
Maintain continuous operation even during peak demand.
Lower overall oxygen supply costs by 30–60%.
Key Features
Oxygen Purity: 90%–95% ±2% (customizable for different treatment stages)
Flow Capacity: Scalable from 5 Nm³/h to 500 Nm³/h to suit small plants and mega-facilities.
Low Maintenance: No moving parts inside the PSA towers, reducing downtime.
PLC Control: Fully automated operation with oxygen flow and purity monitoring.
Modular Design: Easy integration into existing wastewater treatment lines.
Energy Efficiency: Optimized molecular sieve performance for lower kWh/Nm³ oxygen.
Applications in Wastewater Treatment
