It is mainly used for the separation and removal of fine suspended particles with a specific gravity of nearly 1.0. Airflow method (DAF) is a water purifier by making impurity particles adhering on a large number of fine bubbles to form their overall density of <1 state, so the bubble will take the impurities suspend solid rise on the surface to realize solid and liquid separation.
The main design parameters of the DAF process includes residence time, flocculation time, surface loading rate, reflux ratio, dissolved air pressure etc. The hydraulic retention time of the flotation tank is about 5 ~ 35 min with the surface loading rate as 2.5 ~ 8m / (m.h). Optimizing the dissolved air pressure and the reflux ratio can effectively reduce the operation and maintenance costs of the water plant. In addition, due to the short stay time, the cost of floating pond infrastructure costs less than that of sedimentation tank but can get better treatment results.

4. Structure and Working Principle
LIRD-XXX DAF is composed of floating pool body, dissolved air system, dissolved air return pipeline, dissolved air water release device, skimmer ( can be optional for combination style , Driving style or Chain plate style as per requirement )according to user needs can be combined, driving and chain plate) and electric control cabinet And other components.
DAF mainly help with solid-liquid separation (meantime also reducing COD, BOD, color, etc.). In the raw water by adding flocculant PAC or PAM, after effective flocculation reaction (time, dosage and flocculation effect to be determined by the experiment), the raw water then enters into DAF’s contact area. In the contact area, the micro-bubbles in the dissolved water and the flocs in the raw water are bonded to each other to enter the separation zone. Under the action of the buoyancy of the bubbles, the flocs rise to the liquid level with the bubbles to form scum. The scum is scraped to the sludge area via skimmer. The lower fresh water flows through the sump to the clear water tank. Part of the water will reflux for the use of dissolved air system, the other part is discharged.
