Sufficient dissolution efficiency can be obtained even at a relatively low pressure of 2-3 kg / cm 2 . That is, since gas-liquid dissolution can be performed at the above low pressure, the same power consumption results in 5 kg / cm 2 ··· 50 l / min with a 2.2 kW pump and 2 kg / cm 2 ··· 150 l / min. In addition, it is possible to greatly reduce the power consumption with respect to the discharge amount.
