Wet filters
Washers and scrubbers different kind of widely used in all industries, mainly for the adsorption of the dissolved gases. They are not very widely used for air cleaning from solid particles of a dust. Efficiency washer to remove the dust depends on the wettability of the dust and water. This function surface tension of the water while it is in contact with a solid part. Different surface tension force, as a rule, for different materials. Thus, the water finds it very difficult to wet oily materials, but pretty easy to wet lean materials. Examples of fatty materials are atmospheric pollutants present in the urban and industrial environment; thus, washing air is not a very effective way to clean it from dust is usually present. Spray washers should not be considered as filters.
As noted above, air conditioning, washing machine, are an effective way to deal with unwanted atmospheric gases such as sulphur dioxide, which can be taken in a solution of water. Washer water then becomes acidic water and processing and continuous blowdown are needed. Air conditioning, washing machine, are a potential source of bacteria that causes Legionnaires ' disease. This implies that they pose a threat to the hygiene and unwanted in the air conditioning...
