Pay attention to the treatment of printing and dyeing dye wastewater by air flotation machine

Due to its good effect, low investment and convenient operation and management, the air flotation machine has been more and more widely used in the treatment of printing and dyeing dye wastewater. The air flotation method is to generate a large number of micro-bubbles through the device, and add a flocculant at the same time to make the fine particles in the sewage flocculate and adhere to the micro-bubbles, rely on buoyancy to float up and then remove them by a slag scraper to achieve solid-liquid separation and sewage purification.
Bubbles and flocs have a certain degree of hydrophobicity, and they tend to adsorb each other to reduce their surface energy. Under certain hydraulic conditions, micro-bubbles with kinetic energy collide softly with flocs. When particles with hydrophobic groups are adhered by van der Waals force, the more collisions, the stronger the adhesion.
