Sludge Treatment

Air Products’ Halia® sludge treatment offerings provide options to reduce the amount of sludge (biosolids) requiring disposal from your biological wastewater treatment process. The Halia oxygen sludge digestion adds oxygen to an existing aerobic digester increasing the rate of digestion and reducing sludge by 30-60%. The Halia ozone sludge disintegration utilizes ozone to kill the bacteria converting their weight into COD which are then consumed in the biological treatment process thereby reducing the total sludge production by up to 80%.
