Air Products’ Halia® aeration systems use oxygen rather than air as the aeration gas and can be utilized to reduce odor complaints associated with activated sludge basins. Use of oxygen reduces the total gas flow to the basin by 80% while retaining the same level of oxygen supply required to sustain the biological process. In air systems, the nitrogen present in the air passes through the basin in the gas phase and strips organic compounds from the basin which can contribute to odor issues.
