Basic requirements and adsorption of dissolved gas release

The dissolved gas release device is a core device of the air floatation method to a certain extent. When it is used, its main function is to release the gas in the dissolved gas water in the form of fine bubbles to adhere to the suspended impurities in the sewage to be treated. good. The dissolved gas releaser has the largest energy dissipation value. The energy dissipation value refers to the difference between the dissolved energy and the low energy value of the dissolved equilibrium energy, which is close to the normal pressure. The energy dissipation value of the high efficiency dissolved gas releaser should be above 95%, and the highest can reach 99.9%. .

After the two identically sized bubbles of the dissolved gas release are combined, the de-surface energy will be reduced by 20.62%. In order to avoid the merger of microbubbles, the fastest energy dissipation rate, or the shortest energy dissipation time, must be obtained on the premise of obtaining the maximum energy dissipation value. The energy dissipation time of the high-efficiency dissolved gas release device should be below 0.3s, and the optimal one can reach 0.03~O.Ols.

A better-performance releaser can release about 99 010 of dissolved gas at a lower pressure (about 0.2 MPa), that is, almost all dissolved gas is released to ensure a good water purification effect. Less energy consumption. According to the adsorption value theory, only bubbles smaller than the suspended particles can effectively adsorb with the suspended particles. The particle size of suspended particles that are difficult to precipitate or float in a short time in sewage is usually below 50rnn, and the particle size of the main particles of the emulsion is 0.25~2.51um; although the particle size of suspended particles in water can be determined after the addition of coagulant Become bigger. http://www.shallowairfloatation.com/
