Unformatted text preview: characteristics, including air flow rate, bubble size, temperature and mixing intensity, on gas transfer. Aeration Systems There are various types of aeration systems. The most common types used are mechanical aerators and diffused air systems. Mechanical aerators apply energy to the water causing splashing and turbulence to the surface, which increases the gas transfer rate. Diffused air aeration systems bubble air or oxygen through the wastewater, which rise from the floor of the aeration tank and provide the mass transfer of oxygen to the water. The temperature of the water, the size of the bubble, and the rate at which air is added to the water and mixing intensity will all have an effect on the gas transfer efficiency....
