Air pollution effect on living things. The main component due to which air pollution is increasing are carbon- dioxide, which is get exposed from vehicles and other harmful gases which is comes out from the big factories, electric power, generation plants, big industries etc. So it is important to solve these problems by taking serious steps. Aqua silencer is the one of the step taken in reduce the air pollution. It is fitted to exhaust pipe of engine. These silencer are used to reduce the noise and control the emission of harmful gases. The aqua silencer reduces emission noise because, the sound produced in aqua silencer under water having less amplitude than the sound produced in open atmosphere. This is happen because of in water molecules there are small sprockets which lowers amplitude of emission gases and lower the level of sound. The layer of charcoal which is pasted over perforated tube can control the emission by using the activated charcoal and highly porous extra free valences because these layer having high absorption capacity.
