Abstract:

The definitions of bubble size ranges in different kinds of literature are summarized and classified according to their characteristics. The application characteristics of micro-nano bubbles in the air-floating process are summarized, and the influence of micro-bubble particle size distribution and surface charge on the air-floating process is introduced. Based on the size distribution, rising speed, gas holdup, Zeta potential and other characteristic parameters of micro-nano bubbles, various characterization detection techniques of micro-nano bubbles are summarized. The application status, existing problems and prospects of micro-nano bubbles in air-floating technology are summarized, and the development and application of micro-nano bubbles in air-floating technology are prospected.

Key words: micro-nano bubble, air floatation, gas-liquid separation
