DAF Unit (Dissolved Air Flotation Unit):A DAF (Dissolved Air Flotation) unit is a water treatment device that achieves solid-liquid separation by generating a large number of micro-bubbles in the water through the air dissolution system. The air is attached to suspended particles in the form of highly dispersed micro-bubbles, causing the particles to become less dense than water and float to the surface by buoyancy, where they can be removed.
DAF units are available in several types, including super-efficient shallow-layer DAF, cavitation air flotation, and horizontal-flow DAF. They are currently widely used in water supply treatment, industrial wastewater treatment, and municipal wastewater treatment.
The advantages of DAF units include low capital investment, minimal footprint, a high degree of automation, and ease of operation and maintenance.
A DAF unit is a machine that uses fine or micro-bubbles to float impurities out of the water medium. It is particularly suitable for treating water containing fine particles with a specific gravity close to that of water, which are difficult to settle or float by gravity alone.
