Aerosols/Emission Reduction

Air Products’ Halia® aeration systems can reduce aerosol formation and VOC emissions by greater than 90% compared to conventional air systems. Our systems decrease the cost of aerosols / emissions reduction by avoiding the need for covered basins and off-gas treatment, lowering the power consumption, increasing treatment capacity within the existing basin volume and optimising the oxygen injection rate via DO control.
