Halia® Modular Aeration System

Pure oxygen injection for aerobic biological processes

The Air Products' Halia® modular aeration system consists in the combination of a VSA (Vacuum Swing Adsorption) oxygen generator integrated with a low energy mixer aerator. The mixer is mast-mounted allowing easy installation and access. The VSA is based on robust rotary-lobe blower technology. Together they form a novel, efficient, yet easily maintained package capable of delivering dissolved oxygen to any wastewater basin or oxidation tank.

How Can Halia® Modular Aeration System Improve Your Wastewater Treatment?​

Low Emissions

99% of gas leaving the surface of the basin is reduced, and so the VOC and odour levels in the basin are reduced

0884-ruler
High Resistance

Treatments with oxygen generally give higher levels of biomass solids, and avoid typical process failures of air systems

High Efficiency

Specific oxygen transfer rates up to 2kg/kWh can be achieved under operating conditions in the basin environment
