Dissolved Air Flotation System
Features
1. High air-liquid dissolving efficiency
Low voltage operation
Dissolve gas-water dissolving efficiency 80-100%
2. Large capacity, high efficiency and small occupying space.
3. Compact structure, easy operation and maintenance.
4. Silt expansion elimination.
5. Water aeration eliminates active agents and foul smells in water. Meanwhile, the increased dissolved oxygen provides a favorable condition for further processing.
6. This method is highly effective especially when using it with cold water or water with high algae content.
The dissolved air flotation (DAF) system provides effective separation of suspended solids, fats, oils and greases from liquids. Flotation of the solids is accomplished with the introduction of tiny air bubbles into the raw water. As the bubbles rise, suspended particles attach to the bubbles and are carried to the surface for removal.
1. 1---30 m3/hour capacity, the advantages:
1). No air compressor system
2). No air storage tank
3). No water pump
4). No less power consumption
5). Easier operation
6). Automatic operation
7). Low cost
8). Low environmental footprint
2. 30—300m3/hour
1. Design treatment capacity: 30-300 m3/h
3. There two kinds, one is horizontal DAF, the other is vertical DAF.
1. Horizontal DAF is easy to observe.
2. Vertical DAF allows for saving floor space.
3. The effect is the same.
