Dry oxygen generator OXYBERG

industrialprocessfor water treatment

Overview
BERG Kompressoren supplies on-site PSA oxygen generation systems and the associated compressed air infrastructure, air treatment, storage and pressure control required as feed gas for ozone generators in water, wastewater and industrial treatment applications. Systems are configured to provide continuous, project-specific oxygen feed gas for reliable ozonation.

Application challenge
Ozone generators demand a stable, high-quality feed gas. Using oxygen instead of air can improve ozone production efficiency but requires careful supply-side design. Key challenges include logistics dependence on delivered oxygen, compressed air quality, pressure control and handling peak demand and redundancy.

BERG solution
BERG acts as system integrator and supplier, providing engineered PSA oxygen generators and complete compressed air systems with installation, commissioning and service.

• PSA oxygen generators configured for ozone-generator feed gas requirements.
• Industrial compressors (KOMPBERG) sized for oxygen generation and plant utilities.
• Compressed air treatment (DRYBERG, PUREBERG): dryers, filtration and condensate management.
• Oxygen storage and pressure control: receiver tanks, buffer storage and regulation.
• Turnkey skid-mounted or containerized packages including controls and auxiliaries.
• Project engineering, commissioning and long-term service support.

On-site oxygen generation
PSA units deliver continuous oxygen directly at the treatment site to reduce logistics dependency and enable a controlled ozonation feed concept.

• Configuration depends on ozone generator requirements: oxygen flow, delivery pressure and required purity.
• Buffer volume, pressure regulation and dew point are selected per project.
• Systems are application-tailored rather than one-size-fits-all.

Compressed air infrastructure for ozone applications
Reliable oxygen generation requires upstream compressed air quality and stability to protect PSA performance and ozone system operation.

• Compressors are selected for flow, pressure, duty cycle and redundancy targets.
• Dryers and filtration ensure clean, dry inlet air to the PSA unit.
• Dew point control and condensate management maintain stable operation.
• Integration of compressors, dryers, filters, oxygen generator and storage is provided.

Typical application areas

• Wastewater treatment: ozonation and advanced oxidation processes.
• Drinking water treatment: ozone disinfection and oxidation.
• Process water treatment in industrial facilities.
• Industrial water treatment and oxidation applications.
• Ozone-based disinfection and sanitation processes.

Benefits of on-site oxygen supply for ozone generation

• Stable, continuous oxygen feed gas availability for ozone generators.
• Reduced dependency on delivered oxygen (cylinders or LOX) and associated logistics.
• Project-specific system design for required flow, pressure, purity and operating hours.
• Integrated concept combining compressors, dryers, oxygen generation and storage from a single supplier.
• Commissioning, service and long-term support by BERG Kompressoren.

FAQ (selected)

• Why oxygen for ozone generation? — Oxygen feed often enables higher ozone concentrations and more efficient ozone production depending on generator design and operating conditions.
• Can oxygen be generated on-site? — Yes. PSA technology can provide continuous on-site feed gas sized to plant requirements.
• Which oxygen purity is required? — Purity is defined by the ozone generator manufacturer; BERG configures systems to meet project specifications.
• How is system size calculated? — Sizing considers ozone feed requirement, oxygen flow, pressure, purity, load profile, redundancy, ambient conditions and compressed air quality.
