In the case of the dust treating apparatus, dust is adsorbed and removed by using water .

Conventional fluid treatment plants using the above-described methods have appropriate reaction efficiencies to meet their respective purposes. However, since the reaction efficiency is low in actual sites, excessive use of chemicals, increase in power ratio due to extension of equipment operation time, There was a real problem being raised. For example, in the case of a conventional aeration apparatus, although the high pressure compressed air or oxygen is directly injected into the liquid phase, the solubility of oxygen is low. In the case of the degassing apparatus, the efficiency of degassing is low due to low reactivity with air and substances requiring degassing. Even in the case of the malodor processing apparatus and the dust processing apparatus using the oxidation, reduction, and neutralization reactions, the reactivity is low and the overall performance and efficiency are low.

In addition, due to various reasons as described above, the conventional fluid treatment equipment has a low reaction efficiency, resulting in deterioration of performance and efficiency. As a result, The maintenance cost such as the processing cost, the equipment cost and the electric power cost increases, and the processing time is increased, and the productivity is lowered.
