PSA Industrial Oxygen Generator 93% Purity 10-200Nm3/H for Wastewater Treatment Ozone Generation Systems
The Luoming PSA (Pressure Swing Adsorption) Industrial Oxygen Generator is a specialized on-site oxygen supply solution engineered for wastewater treatment facilities, ozone generation systems, and industrial oxidation processes. By replacing costly liquid oxygen deliveries or cylinder supplies, this system delivers continuous 93% purity oxygen at flow rates from 10 to 200 Nm³/h, providing a reliable and cost-effective gas source for critical treatment operations.
Oxygen plays a vital role in modern wastewater treatment through several key processes:
- Activated Sludge Process: High-purity oxygen injection into aeration basins increases dissolved oxygen levels, supporting aerobic bacteria that break down organic contaminants. Oxygen-based aeration achieves 3-5 times higher oxygen transfer efficiency compared to conventional air-based systems
- Ozone Generation: On-site oxygen is the ideal feed gas for ozone generators used in advanced oxidation processes (AOP). Oxygen-fed ozone systems produce 2-3 times more ozone than air-fed systems while consuming less energy per kilogram of ozone generated
- Odor Control: Oxygen-enhanced biological treatment eliminates hydrogen sulfide and other odor-causing compounds more effectively than air-based alternatives
- Chemical Oxygen Demand Reduction: High dissolved oxygen levels accelerate COD/BOD degradation, enabling treatment plants to handle higher organic loads within existing infrastructure
- Twin-tower PSA design with automatic alternating adsorption-desorption cycles
- High-performance Zeolite Molecular Sieve (ZMS) with selective nitrogen adsorption
- Siemen s PLC intelligent control system with 7-inch color touchscreen HMI
- Real-time oxygen purity analyzer with automatic low-purity vent to ensure consistent output quality
- Built-in refrigerated air dryer and multi-stage filtration for compressed air pretreatment
- Remote monitoring and diagnostics via Ethernet with optional 4G connectivity
- Comprehensive safety protections: over-temperature alarm, over-pressure relief, automatic shutdown on fault
- Compact modular design for easy installation in existing treatment plant layouts
- Low maintenance design with molecular sieve life expectancy of 8-10 years under normal operation
- Optional oxygen buffer tank and booster compressor for downstream pressure requirements
