Product Description

In the waste water treatment, solid-liquid separation is a very important process. Dissolved air flotation is one of the most effective methods. GDXF Multiphase Mixture type DAF, as new type flotation equipment, with an excellent sewage treatment technology to remove grease, gelatinous substance and suspended matters easily.

Working Theory

The air and water are inhaled by the multiphase mixture pump at the same time, and the air is dissolved into the water by high speed rotating impeller, then the gas-liquid mixture proportion is adjusted according to the site circumstance to achieve plenty of micro bubbles, which are enough to float the suspended matters. The gas proportion in the gas-liquid equilibrium vessel can reach up to 30% at the best state. The micro bubbles from the air releaser is less than 30um, they stick to the suspended solids and float the surface and then scrapped by the skimmer.

Application
DAF System, as one waste water treatment process, it is widely used in sewage purification engineering. It can be used for these industries:1. Paper industry -- pulp recycle in white water and clean water recycled for use.2. Textile, printing and dyeing industry -- color chromaticity reduction and SS removal3. Slaughterhouse and food industry4. Petro-chemical industry -- oil-water separation
