LP2LP™ Oxygen Enrichment
Advantages and Benefits
Revolutionizing Wastewater Treatment
To meet rising demands for energy-efficient and cost-effective wastewater treatment, PCI Gases has launched the pioneering LP2LP (low pressure to low pressure) oxygen enrichment system. Utilizing PCI’s advanced VSA DOCS (Deployable Oxygen Concentration Systems) units to concentrate oxygen from the atmosphere, then at low pressure, employing market-leading venturi injector and nozzle components to enrich and mix the aeration basin of a water treatment plant. By integrating this system, these treatment facilities can achieve a 30-70% reduction in aeration power compared to conventional aeration methods.
Additionally, the enhanced oxygen availability has the potential to increase the plant treatment capacity by up to 50%. All of this while reducing the CAPEX by almost 30% when comparing other super oxygenation systems. This innovative approach highlights the potential to enhance operational efficiency while lowering costs in modern wastewater treatment facilities.

DOCS Vacuum Swing Adsorption Technology
PCI Gases’ state-of-the-art VSA (Vacuum Swing Adsorption) eliminates many of the design problems associated with traditional PSA (pressure swing adsorption) systems. A single oil-free blower is used for both oxygen production, and waste gas removal from a single adsorption bed. Operating at a lower pressure ensures that the system is not affected by environmental humidity, and the adsorption bed lasts longer. Supplying oxygen at lower pressure also ensures a power saving over other oxygen production systems. PCI’s Deployable Oxygen Concentration Systems (DOCS) reduce both capital and operational costs when compared to conventional systems.
Monitoring and Control
LP2LP™ Operation
The intelligent design of the process allows for accurate monitoring and control. PCI Gases’ DOCS Units are fitted with a mass flow controller that will only supply the oxygen that is needed by the plant. Control is done with a Dissolved Oxygen sensor in the aeration basin. With a high turndown ability, load following capabilities ensure that only the oxygen that is needed is produced, even putting the DOCS into a sleep mode if demand is reduced for an extended period. Remote monitoring allows the operator to keep a close eye on the system, even off-site.
This flexibility in oxygen supply assists with plant operation by being able to adjust to meet variability in incoming effluent qualities and volumes. This ensures a smooth operation of the treatment plant even through peak and off-peak changes.

Total Cost of Ownership
Improve Plant Capacity and Reduce Total Cost of Ownership
By combining the low-pressure oxygen stream from PCI Gases’ DOCS units with the low-pressure demand of the venturi injectors and optimizing the recirculation pump sizing to ensure sufficient mixing energy, the LP2LP enrichment system ensures the lowest-cost oxygen dissolved in the water. The CAPEX of the system is minimised because there are no complex installation requirements, nor any high-pressure system requirements. This enables the wastewater works to save on energy costs, while improving plant capacity and improving effluent discharge quality. The result is the lowest Total Cost of Ownership (TCO), efficient, autonomous supply that is reliable and easy to use.

Common questions about oxygen enrichment for wastewater
Can I increase treatment capacity without building new tanks?
Yes. The enhanced oxygen availability has the potential to increase plant treatment capacity by up to 50% — an increase in capacity of an existing footprint, without adding tanks or reactors.
How much energy does this save over conventional aeration?
LP2LP delivers a 30-70% reduction in aeration power compared to conventional aeration methods, and an extra 15% reduction in power demand over conventional VSA by eliminating the final compression stage.
What does LP2LP stand for?
Low pressure to low pressure. Oxygen is generated at low pressure by a DOCS unit and delivered at the low pressure the venturi injectors need, which removes the final compression stage altogether.
