Degassing tower is a device by the water, fillers, fan and water tank composed of equipment, water equipment commonly used base manifold water distribution, material selection according to different needs, depending on the filler used multi-faceted hollow ball, can be selected according to different water quality ceramic or plastic, he is mainly play a larger surface area of the water, the better carbon dioxide was blown off, the fan is to provide air source, and thus the carbon dioxide stripping the water, the water tank so that the treated water is stored , can be hit by subsequent booster device, in addition to the carbon is working, the water entering from the upper, the leaching water distribution system, through the filler layer from the lower into the water tank, and to provide the wind turbine is the reverse of the , the blow-off from the bottom up, through the filler layer was discharged from the top. The principle so when in addition to carbon is blown into the air flow and in contact with water, in addition to carbon, the water will be the air flow CO2 out.
