Halia® Aeration Systems for Wastewater

Pure oxygen injection for aerobic biological processes

With Air Products Halia® aeration system wastewater is pumped from the aeration basin through a venturi where pure oxygen gas is injected. The oxygen rich stream is returned to the basin using unique liquid-liquid injectors that maximise the gas dissolution and ensure homogeneous distribution of the oxygen and mixing energy throughout the basin.

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

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

High Treatment Rates

Up to 10kg COD/m3/day can be achieved with oxygen-enhanced systems

Easy Installation

The submerged mixer can be mounted onto a guide rail and installed without draining the aeration basin
